Keyshot 2024 - a new version of 3D rendering software

KeyShot is a popular real-time and ray-tracing renderer compatible with various 3D software for rendering, creating animations, and other pictures. It supports more 3D file formats than any other rendering software, with over 25 different file types. KeyShot is known for its user-friendly workflow, which allows professional artists to create photorealistic renders, texture mapping, and simple animation. Luxion recently released its latest update, Keyshot 2024, which includes many new improvements that allow users to focus on performance and workflow updates. This is extremely helpful to 3D artists, allowing them to render more quickly and easily. Let’s learn more in today’s iRender blog!

Overview of Keyshot

Essentially, Keyshot is a visual ray tracing renderer for visualization and portfolio work.

KeyShot is CPU and GPU independent with integrated plugins for many popular DCC and CAD applications. It has an intuitive workflow, intended to enable non-professional artists to create photorealistic renderings of 3D models and increase the capabilities of simple technical animation.

Keyshot 2024 improves image sharpness

Image Source: Keyshot

KeyShot 2024 also provides sharper images when editing your projects, thanks to user interface updates that improve responsiveness. This new functionality allows you to edit directly during the rendering process. Keyshot 2024 adds a new feature called Image Sharpening. This function enables you to take images with outstanding detail. The Image Sharpening tool allows you to modify the intensity, making dark edges darker and bright edges brighter, as well as the Radius, which is the distance outside the sharpened edges that the effect is applied. Your sharper images will also be transferred to KeyShot Web Viewer.

Keyshot 2024 has better GPU rendering performance

The developer highlights that the GPU Mode in the new version of KeyShot uses NVIDIA’s OptiX 8, the latest version of the GPU ray tracing API. Based on internal testing, this increases performance by up to 25%, with a median render speed improvement in GPU Mode of “around 12%”. 

Keyshot also has a number of other small improvements, such as added support for Rhino 8, several CAD versions, and various bug fixes.

Keyshot Web: an incredibly popular add-on

KeyShot Web, which saves you time and is primarily focused on sharing your work outside of KeyShot for collaboration and marketing, has also received an update. For previous versions, the web viewer responded slowly and sometimes artists spent a lot of time waiting. The web viewer in KeyShot 2024 is now more responsive and performs better, as well as having the option to include a 3D scene to perform uploads.

Price and system requirements

KeyShot 2024.1 is available for Windows 10+ and macOS 11.7+. Integration plugins are available for a range of DCC and CAD tools, including 3ds Max, Blender, Cinema 4D, and Maya.

Understanding Physical Lights in KeyShot with iRender

Lights in KeyShot are pretty straightforward. You’ll create better images in no time if you have an in-depth knowledge of the several types of light you can access, how to produce, move, and change them, and when to use each type.

There are two options for lighting your scene with KeyShot. The standard method is HDRIs, however, physical lights can also be used. It also works well to combine physical illumination with HDRI. Simply drag and drop a light material from the KeyShot Library onto a piece of geometry in your scene to add a physical light. KeyShot has five different light material types that each behave differently and offer a variety of purposes for lighting your environment. It would be easier for you to select the best light for your specific situation if you are aware of the many KeyShot light material types. 

In this article today, we will learn about Physical Lights in KeyShot to help you create quality images.

The Different Types of Lighting in KeyShot

In KeyShot, there are actually two different “kinds” of light. HDRIs, which are light from images. Additionally, there are physical lights, which are lights made of materials (called Physical Lights).

Image-based Lighting

High Dynamic Range Images, or HDRIs, include brightness information in addition to color. Using this information, we can illuminate a rendering. Most people find that using high-quality HDRIs makes producing realistic lighting easier and faster. This is partially due to the fact that they were taken with a camera and included a variety of information about the scene. The materials in your rendering look better as a result of these reflections.  

Physical Lights

You can use physical lights to illuminate an object. This transforms the item into a source of light. The scene is lit up by light beams that are projected from the source. Compared to an HDRI, the light behaves considerably more like a real-world light source. The lighting configuration used by a photographer is typically more accurately imitated by employing physical lights. 

How to create Physical Lights in Keyshot

Simply drag and drop a light material from the KeyShot Library onto a piece of geometry in your scene to add a physical light. KeyShot has five different light material types, each of which runs differently and offers a variety of purposes for illuminating your scene.

Area Light Diffuse

Image Source: Keyshot Blog
  • Each surface of the geometry it is applied to emits light, maintaining the geometry’s visibility.
  • Use for shadows and soft lighting
  • Area Each triangle on a surface emits light in a normal direction; if you’re not familiar with triangles, check tessellation.
  • Used most effectively for local illumination
  • To optimize efficiency, only enable the Apply to Front of Geometry or Back of Geometry checkboxes as necessary.

Point Light Diffuse

Image Source: Keyshot Blog
  • A single point at the center of the geometry is applied to emit light.
  • When a point light material is used, the geometry disappears.
  • Use for sharper shadows and highlights
  • Point lights are omnidirectional, they emit light from a single point in all directions.
  • Best for lighting up an entire scene (think of a mini-sun)

Point Light IES Profile

Image Source: Keyshot Blog
  • Because light emits only from a single point in the geometry it is applied to, it is extremely efficient.
  • The geometry disappears and is replaced with an IES cage
  • Since IES Profiles are directed, they can be pointed by turning the geometry they are applied. IES Profiles are pre-made, standard light files with accurate color, shape, and intensity information.
  • Useful for most effectively imitating manufactured light bulbs
  • Adjust the multiplier to change the brightness

Spotlight

  • You can imagine a spotlight as a point of light whose output is cut and whose light is reflected in a cone.
  • The light’s hue may be changed, and you can even control the light’s form and color by putting a stencil texture in front of it.
  • This slider controls the size of a virtual stencil disc that always fits the beam if you apply a texture on the spotlight.
  • When adjusting the light beam’s angle, use the Constant Light Output function for ease. To calculate the size, you can adjust the beam’s angle.

Emissive Light

Image Source: Keyshot Blog
  • Not suitable for lighting a scene
  • Good for low-intensity lighting
  • Each surface of the geometry it is applied to emits light. Comparable to “Area Light Diffuse”
  • used for light-emitting materials such as bioluminescent materials, illuminated displays, and small lights (such as those found in phones, tablets, computers, glow-in-the-dark televisions, and LEDs).
  • Each triangle on a surface is illuminated by emissive lights in the normal direction.
  • Only as needed, apply to the front of geometry or the back of geometry; don’t enable both checkboxes to increase efficiency.
  • Adjust the intensity to change the brightness.

Pros and Cons of Physical Lights in KeyShot

Image Source: Will Gibbons

While it is hard to say that one type of light in KeyShot is inherently superior to another, we can compare their advantages and disadvantages. As mentioned above, HDRIs typically make it simpler for a newbie to get pleasing results rapidly. On the other hand, professionals may frequently achieve a higher level of realism by using physical lights.

Placement of Physical lights in KeyShot

You can put physical lights anywhere in your scene. The exact location of a light source significantly affects how the scene looks. The separation between each HDRI’s “light source” and the object cannot be altered. That’s because each of them is represented by a separate image. This picture encircles the setting like a beach ball. As a result, the distance between each light source and the scene’s center is equal.

The best way to avoid limiting creative direction is to have control over the actual location of the light. The overall appearance of an image can be achieved by strategically placing lighting.

Physical Lights Can Look Boring

The lack of detail while using actual lighting in KeyShot could be a drawback. A plane or a sphere will typically be the only simple shapes used for lights in KeyShot. A viewer can see the light source when it reflects off of bright objects like glass, metal, or glossy plastic.

However, the level of detail in the image is a benefit of HDRIs. A window, for instance, might appear as a light source in an HDRI. A window’s frame, mullion, window sill, curtains, and whatever is outside the window will all be present in this window. All of these particulars add depth, realism, and recognizably reflective surfaces.

Physical Lights in KeyShot Can Add to Render Time

Unfortunately, more realism and complexity also mean longer render times. This is accurate for physical lights. Physical lights allow for better realism while HDRIs simplify the process at the expense of efficiency and render time.

More accurate ray (light) tracing is needed when using physical light sources. This takes longer. with most circumstances, adding real lighting to a scene with KeyShot will make it slower. The likelihood of fireflies will also rise in a scenario with physical lights. This effect can be diminished by increasing the material samples on the light source.

Physical Lights and Shadow Control

One of the main advantages of physical lighting is that it makes it easier to manage shadows. The realism and impact of an image are greatly influenced by the use of shadows. You may make sharper shadows by scaling down a light source. You can soften the shadows in your scene by increasing them. 

You can control scale and hue using physical lighting, which can make your settings come to life. You have control over the shadows’ level of clarity and appearance.

Conclusion

In conclusion, Physical Lights offers a comprehensive lighting toolkit for photorealistic rendering and unlimited control. Fast setup of amazingly realistic lighting is made possible by the accurate simulation of real-world lighting behavior, advanced parameters, and integrated physically-based presets. Physical lights provide the strength and flexibility to realize any lighting concept, whether it’s to replicate a photograph, design a product, or create an imaginary environment.

Speed up Keyshot for Zbrush rendering with Multi-GPU

KeyShot render is an expert in daylighting (atmospheric scattering), light scattering by materials (BRDF and BSSRDF models), light transport algorithms like photon mapping, and real-time rendering technology. Luxion’s KeyShot is an interactive raytracing and global illumination program for both PC and Mac that simplifies the process of creating photographic images from 3D models. KeyShot is simple to use and allows anyone working with 3D data to create photographic-quality images in minutes, regardless of the size of the digital model. This article will learn more about Keyshot for Zbrush.

ZBrush and KeyShot integrate seamlessly.

KeyShot Pro (in conjunction with the ZBrush to KeyShot Bridge) enables you to paint, light, and view your models in real-time, as well as send all model changes back to KeyShot for an unrivaled workflow in creating concepts and product visuals.

KeyShot Pro can be used in conjunction with the ZBrush to KeyShot Bridge on Windows or macOS to enable real-time rendering of your model inside KeyShot. Using the BPR button, you can instantly send all SubTools, including Polypaint and MatCaps, to KeyShot and gain access to hundreds of material and lighting presets, allowing you to create look dev, pre-viz concepts, promo art, and production visuals faster than ever before.

The ZBrush to KeyShot Bridge is a plugin that allows you to send your model to KeyShot with a single click of the BPR button, transferring all SubTools, Polypaint, and textures. Model updates can be sent over via the LiveLinking connection with KeyShot with no need to reapply materials, with all changes appearing instantly in real time.

Basic Workflow from ZBrush to KeyShot

The process of rendering your ZBrush models or scenes in KeyShot is simple and is primarily determined by the materials used in ZBrush.

1. Switching Rendering Engines

To use KeyShot instead of the ZBrush BPR, go to Render >> Ex­ternal Renderer and click the KeyShot button to make it the default rendering engine for ZBrush.

2. Configuring the Bridge Options

Change the various options in the External Renderer sub-palette before sending your data to KeyShot.

The most important setting to take into account is the Auto Merge mode, which we recommend leaving enabled. Please see the AutoMerge function description at the end of this chapter for more information.

3. Data Transfer from ZBrush to KeyShot

With the above settings in place, pressing the BPR button (located in the Render >> BPR Render Pass menu or on the right Shelf in the main ZBrush interface) or the Shift+R hotkey will send your current model to KeyShot, launching it if necessary. If KeyShot is already running, it will use the current instance.

You can have the following scenarios inside KeyShot depending on what you have in ZBrush:

If you have an empty KeyShot scene, the Bridge will build it using the information from ZBrush.

If you already have a model loaded in KeyShot that is made up of one or more Sub­Tools and the same model in ZBrush, the KeyShot scene will be updated to reflect the current ZBrush state. Modified SubTools, as well as new and removed SubTools, will be properly updated in KeyShot.

Note: Even if they haven’t been edited, all visible SubTools are always sent to KeyShot.

If you change the Tool or Project in ZBrush, whatever is currently in the Key­Shot scene will be replaced by what is now in ZBrush. This is analogous to creating a new scene.

It is important to note that the Bridge will not save your KeyShot renders automatically. If you like a render, save it before starting another! Otherwise, the new render will overwrite the old one. The Bridge actions are irreversible.

GPU-accelerated Keyshot for Zbrush

KeyShot has the ability to harness the full GPU-accelerated ray tracing power of NVIDIA RTX with OptiX. Available for both real-time rendering and local render output, KeyShot’s GPU Mode allows GPU resources to be accessed with one-click to take advantage of multi-GPU performance scaling and the dedicated ray tracing acceleration hardware in NVIDIA RTX-capable GPUs. You may toggle between GPU and CPU as needed.

As we all know, ZBrush and ZBrushCore are CPU-based software, meaning that a special video card is not required to get the best results, but when combined with Keyshot, you can save render time when Keyshot use multiple GPUs.

iRender - The Best Cloud Rendering Solution for Keyshot

While Keyshot for Zbrush can take advantage of Multi GPU to speed up render time, iRender is proud to be a professional GPU Accelerated Cloud Rendering Service provider for 3D Render, CGI, and VFX tasks with more than 30,000 clients.

Volumetric Lighting: Create Light Rays in KeyShot https://irendering.net/volumetric-lighting-create-light-rays-in-keyshot/ Thu, 19 Aug 2021 06:00:33 +0000 http://irendering.net/?p=11432 Whether it’s rays of light passing through an exposed window, a stray beam illuminating a neglected furniture piece, or fast-moving vehicles headlights piercing the darkness of night, volumetric lighting can produce incredibly dramatic effects that help better tell the story of your scene. To get started creating volumetric lighting in KeyShot, you’ll first want to consider the composition of your scene - the subject to highlight, where the rays are coming from, how noticeable you want the rays to be. To demonstrate this, let’s use a Spotlight to give a basic understanding of the process, then two ways to use this same concept to create more complex scenes will be shown.

Volumetric Lighting: Create Light Rays in KeyShot

KeyShot has an array of lighting capabilities from simple drag-and-drop HDRI lighting to physical lights, along with lighting presets to get you started and a Light Manager to make controlling your scene lighting easy. KeyShot also has rich volumetric lighting capabilities that allow you to create light rays (god rays) or lights shining through a hazy scene. Today, we’ll show how it’s done using KeyShot’s Scattering Medium and Spotlights.

Whether it’s rays of light passing through an exposed window, a stray beam illuminating a neglected furniture piece, or fast-moving vehicles headlights piercing the darkness of night, volumetric lighting can produce incredibly dramatic effects that help better tell the story of your scene. To get started creating volumetric lighting in KeyShot, you’ll first want to consider the composition of your scene – the subject to highlight, where the rays are coming from, how noticeable you want the rays to be. To demonstrate this, let’s use a Spotlight to give a basic understanding of the process, then two ways to use this same concept to create more complex scenes will be shown.

1. Isolate the Model

In the example scene, the house plant is isolated and prominent with no other details in the background. This is a great method for creating hero shots that illuminate your subject and call attention to details such as surface texture or material properties.

To create this type of composition, you’ll first want to place your subject in the center of your scene and add a Ground Plane (Edit, Add Geometry, Add Ground Plane or Ctrl+G) to give your subject a surface to sit on.

2. Add Spotlight

Next, add a Spotlight (Edit, Add Light, Spotlight or Shift+4) and move it above your object. Adjust the Spotlight parameters to your needs. (Note: If using KeyShot 9 or prior, you will need to first add a piece of geometry to your scene and then apply a Spotlight material from the Materials tab to create a physical spotlight.)

3. Add the Volume

With the light set, go to the Library window, Models tab and add a piece of geometry (like a Sphere or Cube) by double clicking on it. Then, scale the geometry up or down to encompass the entirety of the camera’s view as necessary.

4. Apply the Scattering Medium

Now, switch to the Materials tab and drag and drop a Scattering Medium Fog material. Another quick way to apply the Scattering Medium is to double-click the geometry, which puts you into the Project window, Material tab, and change the material Type to Scattering Medium. The difference is that the Library material is a preset with Transmission Color set to a neutral grey, while changing the material Type to Scattering Medium will set the Transmission Color to the geometry color.

5. Make It Your Own

With your Scattering Medium now applied and your physical light in place, you’re now ready to finalize your composition. At this point, it’s all about adjusting both your Scattering Medium and Spotlight to create the look you’ve envisioned.

You can create stylized effects by adjusting the Spotlight or Scattering Medium’s Color and you can adjust the intensity of your fog-like effect by adjusting both the Scattering Medium Transparency Distance and Density. This stage of your scene building comes down to creative expression and preference, so play with these settings until you’ve dialed in the appearance that best fits your needs.

Some other Pro Tips:

Enable Multiple Scattering: In the Material Properties for the Scattering Medium, you can also enable Multiple Scattering for a more realistic light scattering effect within the medium, while the Advanced options provide more advanced colorization and lighting control, including how the light particles reflect or absorb your medium’s light using Albedo and Scattering Directionality.

Dim the Lights: And lastly, to accentuate the light rays and better isolate objects in your scene, ensure your environment is set to pure black, so that the only illuminated element within the scene is the subject under the spotlight. Do this by going to the Project window, Environment tab and setting Brightness to 0.

Advanced Application for Volumetric Lighting

In this scene, the same concept of spotlighting through scattering medium has been used to call attention to the motorcycle’s headlights and taillights, while at the same time giving the scene context in terms of the environment it might currently be in. Not only does it create a dramatic composition, but it evokes a feeling that we are currently viewing the bike in a dark, hazy environment, perhaps a city street, or parked in some dark back alley, illuminated by a nearby light. 

This interior scene demonstrates a more subtle effect. It uses a physical light to cast light through an open window creating a sunlit effect, while the Scattering Medium helps add a moodier undertone to the composition. In both, the volumetric lighting helps to elevate the story and mood of what would otherwise be a relatively plain scene, while allowing the viewer’s imagination to engage more deeply with the visual they’re looking at.

Conclusion

Hope that with these above instructions, designers could have more understanding about Volumetric Lighting in Keyshot and could give more realism into your scene to feast customers’ eyes. And if you are having troubles in selecting a render farm for Keyshot? And you don’t know what the best cloud render farm for your needs, don’t worry.  iRender provide various multi-GPU-servers (  1/2/4RTX 3090 and 4 RTX 3080) which are the most effective for Keyshot rendering in GPU, coming with the following specifications:

Using Keyshot Mesh Simplification Tool

KeyShot is a stand-alone, real-time ray tracing and global illumination program used to create 3D renderings, animations and interactive visuals. With its CPU-based architecture, photo realistic real-time rendering can be achieved on both Mac and PC, even on laptops, without the need for high-end graphics cards. KeyShot supports more 3D file formats than any other rendering software, importing over 25 different file types. It has a simple user interface with drag-n-drop material and environment presets, interactive labeling, texture mapping, physical lighting, animation, etc.

Though KeyShot is able to import and work with very large, very detailed data sets with very complex geometry and textures, there times when you may want to simplify the geometry of the model. Here, we’ll take a look at how to access the Mesh Simplification tool and how to use it along with some tips on how to control the mesh quality.

What is Mesh Simplification in KeyShot

The Mesh Simplification tool in KeyShot Pro allows you to quickly reduce the triangle counts of your mesh-based models. This is useful for reducing the file size or complexity of a model for use with KeyVR or for other web and AR applications, or may be applied to more creative uses, such as creating low-poly versions of objects.

1. Activate Mesh Simplification Tool

Access the Mesh Simplification tool from the Tool icon on the KeyShot Ribbon or right-click on the individual part of the model you would like to simplify and select Mesh Simplification from the pop-up menu. The Mesh Simplification window appears and displays your selected geometry’s mesh as a grey wireframe. In the left pane, you’ll see the Mesh Quality parameter, which can be controlled via the slider or by inputting a value between 0 (fewer faces/lower quality) and 1 (more faces/higher quality).

2. Preview the Simplified Mesh

To preview changes before applying them, choose the desired value and select the Simplify button located above the slider. The viewer displays the updated wireframe with the selected mesh quality. At the bottom left of the window, the Nr of faces displays the updated triangle count.

3. Apply the Simplified Mesh

Once you’re satisfied with the mesh quality, hit Apply at the bottom right to update your geometry in the Real-time View. With a lower polycount, you may notice some areas on the surface where your model does not look as smooth as it previously did. If you’re not comfortable with the appearance of the new surface, you can always use Ctrl-Z (Windows)/Option-Z (macOS) to undo the mesh quality adjustments, then re-open the Mesh Simplification window to apply a new setting.

4. Controlling the Mesh with the Edit Normals Tool

Another way to control the mesh quality is to first re-calculate the vertex normals of the geometry with the Edit Normals tool, accessed from the same Tools or right-click menu. Once open, simply select Calculate Vertex Normals in the left pane then the Apply button to the lower right. This will improve the appearance of an object’s low-poly surface while not adding to the model’s triangle count. You can then repeat this step for any surface or part you would like to improve.

Hope that with these above instructions, designers could have more understanding about Mesh Simplication tool in Keyshot and could give more realism into your scene to feast customers’ eyes. And if you are having troubles in selecting a render farm for Keyshot? And you don’t know what the best cloud render farm for your needs, don’t worry.  iRender provide various multi-GPU-servers (  1/2/4RTX 3090 and RTX 3080) which are the most effective for Keyshot rendering in GPU, coming with the following specifications:

Adding textures and materials to labels in Keyshot

KeyShot is well-known as one of the best 3d rendering software to create amazing visuals. It is a real-time ray-tracing and global illumination program that displays results instantly and reduces the time to create realistic product visuals. Keyshot is gradually becoming one of the most favorite and popular 3D software chosen from artists all over the world with its amazing features. It supports importing the greatest number of 3D file formats out of any rendering software, and has an incredibly simple user interface with drag-n-drop material and environment presets, interactive labeling, texture mapping, physical lighting, animation and much more. Additionally, the software includes native support for over 30 leading 3D file formats, allows to keep the design in-sync across applications, reduce time for loading and increase time for creating. KeyShot allows you to more accurately communicate the physical properties of your labels by applying materials and textures to them. Of course, you can simply add a label to a surface and run with the default settings but you can push the realism even further with simple adjustments to material and texture.Let’s figure out how to do it now!

KeyShot allows you to more accurately communicate the physical properties of your labels by applying materials and textures to them. Of course, you can simply add a label to a surface and run with the default settings but you can push the realism even further with simple adjustments to material and texture.Let’s figure out how to do it now!

KeyShot Materials & Labels

In KeyShot, labels may be applied as an image, video, or material. When a label is added to a surface, it appears in the Project, Material, Labels tab. When a label is selected from this list, you can view it’s Type, Properties, Textures, and Mapping parameters. Let’s take a closer look at what happens after you apply a label.

Label Type

By default, the Label Type is set to Plastic. To change this, select a different material from the Label Type dropdown or drag and drop a material from the Materials Library onto the label in the list.  The associated Label Properties and Label Textures will update according to the type selected. You can adjust your parameters here In the Label Properties tab just like you would for any other material.

Label Position

To quickly make changes to the position of your label, go to the Label Textures tab and  select Move Texture from the mapping controls. Make sure you use a Mapping Type that correlates to the surface the label is applied to (e.g. Planar for a flat surface, Cylinder for a cylindrical surface, etc.).

Label Color Variations

If you need to create multiple color variations for your label, apply a white version of your label and use the Blend with Color checkbox in the Color properties. Simply, duplicate the label and change the Blend with Color selection as many times as you’d like to populate the list with different color variations.

Add Texture to Labels

Assigning textures to labels is just as easy. Simply select the Label Textures tab, then drag and drop a texture onto the Bump channel. From the Texture dropdown, you can select a different type of texture or, if the parent material has a texture, you can incorporate the texture by selecting the From Parent option.

Apply Parent Texture to Labels

If you want the parent texture to apply to multiple labels, go to the parent material’s Texture tab, select the Bump channel, and enable Apply Bump to Labels. This also provides the benefit of freeing up the label’s Bump channel when you would like to add additional bump texture maps. For example, you could hold the Alt-key, then drag and copy the label to the Bump channel to give the label some thickness.

Texture Sync

When mapping textures, it’s always important to be aware of the Sync option. When Sync is enabled it will match the size and position across the texture channels. But, for example, if you have an opacity map applied to a label and want to adjust its scale independent of the label scale, you should first disable Sync to do so.

As you can see there’s a lot of flexibility with labels. So to more accurately visualize and communicate your designs check out these material and textures options, and learn more about Labels in the KeyShot Manual.

Conclusion

Hope that with these above instructions, designers could have more understanding about adding textures and materials  in Keyshot and could give more realism into your scene to feast customers’ eyes.

WHAT’S NEW IN KEYSHOT 10.2?

As we all know, KeyShot is a stand-alone, real-time ray tracing and global illumination program used to create 3D renderings, animations and interactive visuals. With its CPU-based architecture, photo realistic real-time rendering can be achieved on both Mac and PC, even on laptops, without the need for high-end graphics cards. KeyShot supports more 3D file formats than any other rendering software, importing over 25 different file types. It has a simple user interface with drag-n-drop material and environment presets, interactive labeling, texture mapping, physical lighting, animation, etc.

On June 2nd, 2021 Luxion announced to officially release KeyShot 10.2 with many new features and improvements in the areas of materials, geometry, and workflow. Let’s check out the captivating visuals and top features to see what’s new in Keyshot 10.2 now!

Leading the new features are major improvements for caustics, a revamped Materials Library, a new touch-friendly Configurator style, and a new Mesh Simplification Tool, along with new import options and many other improvements across materials, user interface, and workflow capabilities.

KeyShot 10.2 Feature Highlights

The following highlights the top features in KeyShot 10.2. More details and examples of the new capabilities across KeyShot 10 are available at keyshot.com/whats-new/. The entire list of features and improvements in KeyShot 10, along with information on how each feature works, is available in the KeyShot 10 What’s New Guide. Key new features include:

Caustics

A new caustic algorithm was developed for KeyShot 10 with additional refinement and speed improvements made in KeyShot 10.2. The new algorithm can handle thousands of lights, runs blazingly fast on the new NVIDIA RTX Ampere GPUs, and allows details and fine structures in the caustics to be seen in a fraction of the time, both up close and at a distance. Additionally, caustics have been improved for smooth environment lighting and more consistent brightness. Read more about Rendering Caustics in KeyShot on the GPU.

Axalta Paints

The KeyShot exclusive set of Axalta paint materials now offer the possibility of adding metal flakes to the paint with new options for Flake Size and Flake Density. Additionally, the metal flakes are randomly distributed and will match the specular reflection and color of the underlying Axalta paint material.

Materials Library

The KeyShot Materials Library has been completely re-done with new material-specific thumbnails to visualize material appearance and properties more accurately. With this, users now have the option to select the thumbnail style from among seven different models for preset, downloaded, or newly created materials. Along with this, the library will now load resources dynamically, no longer locking the library while loading. Note: it is recommended to use the full installer to load this new functionality.

Touch-Friendly Configurator

Touch-Friendly is a new Layout Style available in the Configurator Wizard that provides a minimal, touch-friendly interface for Presentation mode. The new style provides customization options specific to the interface elements including options for size, color, styling, and icons. Previous configurators may be updated to use the new style by choosing the Touch-Friendly in the Layout Style options.

Mesh Simplification Tool

Mesh Simplification is a new Geometry Tool that allows a user to reduce the number of triangles in a mesh while keeping the overall shape. This is useful to simplify geometry for later use in KeyVR or other AR applications where performance relies on the number of triangles in the model. This tool is similar to the Re-Tessellate tool that requires NURBS to calculate the new mesh. For models that do not have any NURBS, the new Mesh Simplification tool prevents the need to reduce the quality in the modeling software only to re-import it into KeyShot. Learn more about Mesh Simplification.

Additional Features

Other updates users will find in KeyShot 10.2 include:

Link Duplicate Materials: allows users to easily locate and link scene materials that are the same.

Metallic Paint: improved visual appearance of metallic paints with clear coat roughness

Split Object Surfaces: Split Object Surfaces Tool has a new brush select option

Export/Import: improved materials for USD/glTF export plus new glTF Import and Draco compression for Export; improved FBX import; updated support for Creo View, CATIA V5, Jt (up to 10.6), Parasolid (up to 33.1); support for Maya 2022, SketchUp 2021

Headless version: improved to provide more functions and separate executable

Conclusion

Hope that with these above information, 3D artists could have more understanding about Keyshot 10.2 and could make use of its great features to feast customers’ eyes.

Additionally, the software includes native support for over 30 leading 3D file formats, allows keeping the design in sync across applications, reduces the time for loading, and increases time for creating. 

And one of the quickest and easiest ways to give your product or vehicle renderings more realism is to add presence in your scenes by setting them on a surface and adding a nice shadow or ground reflection. You may have used KeyShot geometry, a table or podium model, or even a duplicate of the object itself to showcase the product on what appears like a real-world surface. But hands down, the easiest way to achieve that effect is to add a Ground Planes in Keyshot. Let’s take a look at how to do so and how to work with them. 

Add a Ground Planes in Keyshot

To add a ground planes in Keyshot to your scene, simply click on the Edit  on the main menu, select Add Geometry and choose Add Ground Plane from the menu, or use the Ctrl+G hotkey to add it quickly.

Add Models with a Hotkey (and Customize it!)

If there are Library Models you add to your scene regularly, you can assign a hotkey to add them more quickly. You can update the hotkeys under Edit, Preferences, Hotkeys or, in the Library, Models tab, right-click on the model, select Assign Hotkey, and choose the one you would like to use.

Once selected, the ground planes in Keyshot will be added to your scene. You may not see it but, don’t worry, it’s there. In the Project window, select the Scene tab, then select the Ground Plane under the Model Sets. You’ll see an orange outline appear around the edge of the ground plane in the Real-time View.At this point, you may also notice that shadows and ground reflections appear no different than before adding the geometry. Let’s look at two ways to change that.

Add a Material to a Ground Plane in Keyshot

A common method is to apply a material that has the qualities you’d like for a ground surface. For instance, when you add a rough black metal material you’ll see a nice, diffused reflection on a neutral-colored surface. From this point, adjust the ground material as you would any other material in KeyShot.

Depending on your camera angle, this can create a horizon line in your scene which may or may not be desired. If you prefer a seamless ground plane you can adjust the camera angle, increase the size of the ground plane, or adjust the ground plane material settings.

Adjust Material Properties of a Ground Plane

For this method, double-click the ground plan in the Real-time View to view the Material properties in the Project window.

Adjust Specular Color: Click the Specular color and change it from black to white. You should see a reflection of your model appear on the ground plane’s surface. Next, adjust the Reflection Contrast slider from 0 (a very faint reflection) to 1 (a very defined reflection).

Adjust Roughness: Once you have a desired appearance, adjust the Roughness slider to diffuse the model’s reflection, if desired. Generally, even highly reflective surfaces have a little texture, so unless you’re trying to make your object look like it is sitting on top of a mirrored surface, it’s a good idea to give the ground surface a small amount of roughness. On the other hand, if your goal is to create a more emphasized shadow, you can crank up the roughness to diffuse the reflection to a point where it is unrecognizable and appears more shadow-like.

Adjust Refractive Index: You can also adjust the Refractive Index to increase or decrease the amount highlights/colors are picked up in the ground’s reflection. Increasing this will make the colors more pronounced.

Clip geometry below ground: The Clip geometry below ground option will ensure any geometry below the ground plane is not visible. While this is generally not needed for most product renders, this is often used on automotive images to clip the tires and provide a more realistic appearance of tire compression. Without this, you would see a portion of the tires below the ground plane.

Activate Ground Illumination: It’s also good practice to activate Ground Illumination so light is reflected off the ground back onto your model in a more natural way. To do so, simply click the checkbox.

Bonus tips

At this point, your scene should have a ground shadow and/or reflection that makes your model pop, but there are a couple more tips to share.

One advantage of the second method above is the ability to seamlessly blend a background. Whether you use an HDRI, a solid background color, or a backplate image, this method allows you to quickly and easily make your models fit naturally into any environment of your choosing. Then, you can add multiple environments to explore your model under different lighting and background conditions.

Lastly, if you use KeyShot Pro, you have the ability to jump into the Material Graph and add textures to the ground plane as you would any other material. Give it a try to explore some of the different texture options within the graph and add some interesting effects or a bit more realism to your scenes.

Conclusion

Hope that with these above instructions, designers could have more understanding about ground planes in Keyshot and could give more realism into your scene to feast customers’ eyes. And if you are having troubles in selecting a render farm for Keyshot? And you don’t know what the best cloud render farm for your needs, don’t worry.  iRender provide 3 types of multi-GPU-servers (6x GeForce RTX 2080 Ti / 6x RTX 3080/ 6x RTX 3090) which are the most effective for Keyshot rendering in GPU, coming with the following specifications:

These servers are the ultimate online solution for KeyShot rendering allowing up to multiple, powerful 6x GeForce RTX 2080 Ti / 6x RTX 3080/ 6x RTX 3090 GPU. And, you can control the power and performance for the highest level customization and configuration in application resource usage. These servers are the premier solutions to maximize your advantage when you need it most – to win the project, to meet the impossible deadline, or pivot your visual direction with unparalleled speed.

Rendering Caustics in Keyshot on the GPU

Caustics in Keyshot are among the most beautiful lighting phenomena in nature. Caustics are formed as light refracts through or reflects off specular surfaces. Examples include the light focusing through a glass of cognac, the shimmering light at the bottom of a swimming pool, and even the beams of light from windows into a dusty environment.

1. Introduction about Caustics in Keyshot.

Photon mapping works by tracing photons from the light sources into the scene and storing these photons as they interact with the surfaces or volumes in the scene. The second step is rendering the scene using a ray tracing (or path tracing) algorithm that uses the photons to compute caustics and other lighting elements. The original photon mapping algorithm can render beautiful caustics and global illumination, but it is limited to the number of photons that can be used to render a given scene.

Progressive photon mapping is the first algorithm capable of rendering global illumination and caustics in general scenes. To illustrate this figure 3 shows a simple reflective cube on a diffuse plane illuminated by a point light source. If this cube is rendered using path tracing it completely lacks the caustics due to light reflected off the cube onto the diffuse plane. More advanced algorithms such as bidirectional path tracing, metropolis light transport can render the caustics on the diffuse plane, but none of these methods can render the reflection in the cube of this caustics (what is known as a specular-diffuse-specular interaction). Several current “physically based renderers” can only render the caustics shown in the middle image and lack the ability to render the reflection of caustics. Progressive photon mapping renders everything including the reflection as shown in the right image in figure 3. The progressive photon mapping algorithm is illustrated in figure 4.

KeyShot has been using progressive photon mapping since its inception, and KeyShot has been able to render caustics with a single click since the first release. KeyShot is using a newer development of adaptive progressive photon mapping to compute both caustics on complex indirect illumination. This algorithm is quite complex and it requires complex data structures to keep track of the photons and it runs only on the CPU.

2. Blazingly fast caustics on the GPU.

KeyShot 9 was the first version of KeyShot that took full advantage of the GPU. The RTX technology coupled with the mature CUDA programming framework made it possible to get everything ray tracing, photon mapping, shading etc. running on the GPU. The end result is a caustics algorithm that can handle thousands of lights, quickly render highly detailed caustics up close, and runs blazingly fast on the new NVIDIA RTX Ampere GPUs.

The new RTX GPU-based caustics in KeyShot 10 is a tool for anyone working with transparent or reflective products like perfumes, jewelry, lighting designers and more. Arguably this is the best algorithm out there for displaying caustics on GPU or CPU. GPU rendering in KeyShot is a feature available for both real-time rendering and local rendering. It features a one-click GPU render mode to leverage the performance of multiple GPUs and dedicated ray tracing hardware acceleration in NVIDIA RTX-enabled GPUs. You can change between GPU and CPU if needed or even use one for rendering and one for working which opens up huge performance improvements and gives more flexibility to your scene setup, workflow, and output.

Keyshot can use the computer’s central processing unit (CPU) or graphics card (GPU) to render. CPUs and GPUs are essentially the same in terms of how they are handled. CPU and GPU Rendering usage depends on usage needs. Specifically, with the architecture industry, most architects tend to render via CPU rather than GPU, although it takes more time but will produce higher quality images.

In contrast, industries specifically designed to manage complex, graphics-intensive, virtual reality and artificial intelligence (AI) innovations such as filmmaking, animation, and product design can benefit more from GPU rendering. Because GPUs are much more powerful and, unlike CPU technology, they can process instructions of multiple cores from start to finish at the same time. This will allow your render times to be at least 10 times faster.

To reduce rendering time, you might consider investing in a multi-core CPU processor (e.g. Dual Xeon) and a GPU with a high CUDA core count because GPU rendering allows you to speed up rendering. according to the number of graphics cards in your computer.
