NVIDIA Iray is a powerful, unbiased GPU-based render engine available in Daz Studio, alongside the original 3Delight renderer. In this guide, we’ll explore the best settings for iRay in Daz3D to help you achieve high-quality renders efficiently.

Before fine-tuning render settings, it’s important to configure your General settings properly. Set a clear save location and make sure your output resolution is correct.

You can choose from several built-in resolution presets like VGA or Panorama. For custom sizes, select Custom and enter your preferred pixel dimensions and aspect ratio.

Recommendation: Use double your desired resolution for rendering, then downscale in an image editor (e.g., Photoshop) for better results.

There are 3 options:

• Still Image (Current Frame) – for a single render
• Image Series – for animations, one frame at a time
• Movie – exports a full animation in one file

Recommendation: It’s safer to use Image Series for animations. That way, if rendering gets interrupted, you can resume from the last saved frame instead of starting over.

Decide whether your render opens in a new window or saves directly to the file.

Specify a file name and choose where it should be saved.

Recommendation: If you’re using iRender’s servers, save to any folder on the Desktop to avoid potential errors or crashes.

The headlamp is useful during scene setup for visibility if no lights are present. 

Recommendation: For final rendering, it’s usually best to turn it off to avoid unwanted lighting.

Here, you’ll choose between:

• Photoreal – the highest quality option, ideal for realism
• Interactive – faster previews with lower accuracy

Since Iray is known for its physically accurate results, we’ll focus on the best settings for iRay in Daz3D using the Photoreal mode.

Note: Some render settings may differ slightly depending on the mode selected.

To get the best balance between speed and quality in Iray rendering, it’s essential to understand how progressive rendering works. These settings affect how the image updates while rendering and when rendering stops.

These settings determine how frequently the image updates during the rendering process:

• Min Update Samples: Sets the minimum number of samples per pixel required before the image refreshes on screen. A higher value means less frequent updates, but potentially cleaner previews.
• Update Interval: Defines the time (in seconds) between updates, regardless of how many samples have been calculated.

Recommendation: Most Daz3D users leave Min Update Samples at 1 and keep the Update Interval at its default value for smoother visual feedback during rendering.

Min Samples and Max Samples determine the range of samples per pixel that Iray needs to calculate before finishing the render. Max Time limits how long Iray will spend rendering. All three settings can work together, which means the rendering whill stop when any one of them is reached.

Recommendations:

• Min Samples: Often left at 0
• Max Samples: Increased for higher detail — portraits may go up to 15,000–40,000
• Max Time: Can be left at 0 (no time limit), or set based on how long you’re willing to wait
• Leave Min Samples at 0 and raise the Max Samples and Max Time values to improve image quality, accepting longer render times as a trade-off.

• Rendering Quality (default = 1): Controls final image accuracy. Doubling this value roughly doubles the render time.
• Converged Ratio (default = 95%): Specifies when Iray considers the image “complete.” Raising this may improve quality, but also significantly increases render time.

Recommendation: Keep the default unless you absolutely need cleaner results. Adjust with care.

The Alpha settings affect how transparency is handled in renders. The only adjustable option here is Default Alpha LPE (Light Path Expressions).

Recommendation: Unless you’re having issues with transparency or rendering alpha maps, it’s best to leave this setting at “specular transmission objects.”

Focus on these two key options for optimization:

Caustics are the light patterns formed when light is refracted (through glass) or reflected (off shiny surfaces). These effects can add realism but significantly increase render time.

Recommendation: Enable Caustic Sampler only if you’re rendering glass, water, or reflective materials and want physically accurate lighting.

Guided Sampling helps speed up Iray rendering and reduce noise, especially when used alongside the Firefly Filter. It may increase the memory usage, but the visual payoff is worth it for complex lighting.

Recommendation: Turn on Guided Sampling if your scene includes:

• Large soft shadows (from big area lights)
• Volumetric effects (e.g., fog)
• Occluded or indirect light sources
• Moderate caustics (but not full caustic rendering)

In the latest version of Daz Studio, the Filtering tab becomes visible once you click the Render button. 

During rendering, it’s common to encounter small, overly bright white pixels scattered throughout your image, often referred to as “fireflies.” These occur in areas where lighting is difficult to calculate accurately. The Firefly Filter is designed to automatically eliminate these spots and improve image quality. 

Recommendation: It’s highly recommended to keep this filter enabled in all your renders. For better results, especially in challenging scenes, it’s also advised to use it in combination with Guided Sampling.

This filter helps reduce overall noise in your image without sacrificing too much detail. You can adjust this filter on a scale from 1 to 5. Lower values like 1 to 3 offer a more conservative approach, focusing on reducing noise in difficult parts of the scene while maintaining sharpness. 

Note: Firefly Filter and Noise Degraining Filter are not supported in Interactive rendering mode.

It is especially useful in scenes with complex lighting and shadows. This tool enhances the image after rendering has reached a certain stage, helping to clean up remaining visual imperfections. However, because it uses additional memory and can affect performance, it’s important to use it wisely. Make sure both the “Available” and “Enabled” options are active if you decide to use it. 

Post Denoiser Start Iteration determines how soon in the render process the denoiser begins its work. If it starts too early—like at the default setting of 8 iterations—it can result in longer render times and a blurrier image. A better approach is to delay the denoiser until the final few hundred iterations. For example, if you’re rendering 500 total iterations, starting the denoiser around iteration 250 to 350 will save memory and produce a sharper, cleaner result.

Post Denoiser Denoise Alpha is useful if your render includes transparent elements and you want to reduce noise in the alpha channel. Just be aware that enabling this option can potentially double denoising time. Still, it’s worth using if you notice transparency-related noise in your final image.

Spectral Rendering is a specialized feature that simulates light and color based on real-world wavelengths rather than relying solely on the RGB color model. This method provides more physically accurate color interactions, which can make a noticeable difference when rendering materials like glass, liquids, or skin. 

In most cases, especially for casual or intermediate users, it’s recommended to leave Spectral Rendering disabled unless you’re aiming for highly realistic lighting effects and are comfortable adjusting your workflow to match. While the feature can produce stunning results, it also increases render time and can complicate color management if you’re not familiar with the underlying color theory.

When White Mode is enabled, Iray Interactive applies a plain white diffuse material to all objects in the scene. This mode helps evaluate lighting and shadows without the distraction of surface textures or colors.

Section Objects allow you to visually “cut” through a 3D model or scene, exposing the interior without altering the geometry. You can add an Iray Section Plane via the Create dropdown in Daz Studio. 

Enabling Section Caps fills in the cut surfaces with a solid material or color, instead of leaving the openings hollow or transparent.

In newer versions of Daz3D, the Tone Mapping tab will appear after clicking the Render button.

This feature controls how lighting and color are balanced in the final image (similar to camera exposure settings). Adjusting tone mapping can help fine-tune brightness, contrast, and overall mood of your renders. 

Most users are fine with the default settings, but if you’re curious, I recommend a tutorial video like “Daz Studio: Using Tone Mapping – NotFromThisWorld”.

Found under the Environment tab (after hitting Render), this section lets you define the lighting and ambiance of your scene. The core setting here is the Dome, which controls lighting direction, reflections, and general atmosphere. For example, a dome with a sunny forest scene will reflect that environment’s light and mood.

You can choose from several Environment Modes:

• Dome and Scene: Combines dome lighting with your scene’s lights (e.g., spotlights) 
• Dome Only: Ignores any lights in your scene and uses only the dome.
• Sun-Sky Only: Uses only the simulated sun and sky from the dome.
• Scene Only: Uses just the lights you’ve placed in the scene, ignoring the dome.

Recommendation: Stick with “Dome and Scene” if you want flexibility and better lighting control for most renders.

Finally, when discussing the best settings for iRay in Daz3D, it’s essential to consider the Hardware section. Here, you can select whether to use one or more GPUs, the CPU, or a combination of both for rendering. GPUs offer a significant performance advantage, especially for complex scenes, and can dramatically reduce your Iray render times. While combining CPU and GPU is an option, it doesn’t always lead to better results and may actually slow things down in some cases.

For the most efficient rendering, it’s generally recommended to rely on GPU-only rendering, particularly if you have access to multiple GPUs, as this can greatly boost both speed and quality.

Daz Studio is a computer graphics program for creating highly configurable 3D scenes, from scratch or from pre-imported models. It’s a very famous tool for 3D artists and creators, with robust and vast variety support of different tools and assets (such as posing, wardrobe, hairstyle, background, etc.). With its easy-to-use workflow and free subscription, Daz Studio is preferred by many. The rendering tool often come free with Daz is iRay by Nvidia.

In this article, iRender guides you on the system requirements and the best cloud rendering service for Daz Studio and iRay.

In this section, we will introduce and suggest a system requirement for Daz Studio 4.21:

• • • • Operating system: 64-bit operating system
      • Processor: Intel Xeon/Core 2 Duo or Quad /Core i7 or AMD Opteron/Phenom processor
      • Memory: 2 GB RAM min (3GB+ RAM recommended)
      • Disk space: 1GB free hard drive space for installation
      • Graphics card: Nvidia RTX 2060 or above

However, these hardware are outdated and we will need to deep dive into what is recommended for Daz and iRay.

• • • • Processor: this is not an important factor when you work with Daz Studio and iRay. However, of course you will need an strong enough processor to handle the GPU.
      • Memory: minimum RAM should be 32GB. Or you can base on the VRAM of your GPU to decide how many RAM you will need. According to Daz users experience, RAM should be 3x more than VRAM to make sure your scene will not run out of system memory.
      • Disk space: there’s no recommended space, but you will need large hard drives because Daz’s library is often large.
      • Graphics card: Nvidia RTX 2060 or above is okay for a good start.

iRender provide to you high performance and configurable server system for 3D rendering, AI Training, VR & AR, simulation, etc. We believe that design and creative activities are private and personal that only you artists will know what you want with your animation. That’s the reason why we provide remote servers so that you can install any software you need, and do whatever you like with your project.

You will only need to install your software for the first time, and next time you connect to the computer everything is ready for use.

Because Daz studio and iRay can utilize the power of GPU rendering, we have established some of the fastest server packages with RTX4090 and RTX3090.

One of the best cloud rendering service for Daz Studio

Regarding the most important factor: Graphics card (GPU). Because Daz and iRay recommends powerful cards (especially Nvidia one), we will check the render times of famous GeForce GPUs like RTX 3090 and RTX 4090. All of them render the RayDAnt_DS_Iray_Benchmark_2019A_r4.duf from Daz3d.com’s forum.

The first benchmark is Daz 3D:

In this table of render times for Daz, RTX 4090 is the fastest card, only takes 1 minutes and 4.23 seconds to render the file. When you stack more GPU, the render time will reduce to 25.81 seconds. However, it’s not linear, as 3 x RTX4090 is only 2.5 times faster than 1 x RTX4090.

RTX 3090 renders the scene in 2 minutes 7.21 seconds, about two time slower than one RTX 4090. So it actually follows the trend of Nvidia of making new generation doubles the performance of old generation.

The second benchmark is iRay, same scene:

With iRay, RTX 4090 still shows its superior, with render time is 62.449 seconds. RTX 3090 render time is, once again, about 2 times slower than one RTX 4090.

However, when we see iRay performance on multiple RTX 4090s, the speed is better than Daz test. Here 3x RTX 4090s is about 2.9 times faster than one RTX 4090, so it’s kinda linear when it’s come to speed.

So in general, we can see that RTX 4090 is about 2 times faster than RTX 3090. Multiple RTX 4090s is faster than single RTX 4090, but it’s not a perfectly linear reduction in render time.

iRender provide you RTX 4090 and RTX 3090 server, both of the graphics cards have 24 GB VRAM. The RAM is 256GB, about 10.7 times more than VRAM, so you will not have to worry about the case of running out of RAM when rendering your scene. Storage is NVMe SSD with 2TB for your library content. Processor is an AMD Ryzen Threadripper processor. With those configs, you can be assured that your scene will load faster, more stable when running with multiple applications.

At iRender, we provide you more support than just those config.

iRender offers a powerful and free file transfer tool: iRender drive for macOS and Linux user. With fast file transfer speed, large data capacity, and completely free. You can transfer all the necessary data into our iRender drive tool at any time without connecting to the server. The data will be automatically synchronized in the Z drive inside the server, ready for you to use.

The tool is also integrated into iRender GPU app, an all in one application where you can free your workflow from accessing iRender website, and just have to work on the iRender GPU app.

Beside hourly rental, you can always save from 10% to 20% with our Fixed Rental feature. For those who’s in need of a server for more than a day, or have extremely large projects, we advise to choose a daily/ weekly/monthly rental package. The discount is attractive (up to 10% for daily packages, 20% on weekly and monthly packages), and you don’t have to worry about over-charging if you forget to shutdown the server.

With us, it does not matter where you are present – as long as you are connected to the internet, you can access and enjoy the 24/7 rendering services that we provide, and if you meet any issue, our real human 24/7 support team is always ready to support you.

When you use iRender, you can free your computer during the hardest and most arduous part – rendering. That is also the reason that Render Farm service is becoming more and more popular and essential. However, as far as we know, iRender is proud to be one of the very few rendering service that support powerful RTX4090 and RTX3090 for Daz Studio and iRay with relatively reasonable price.

With the above advantages and the machine configuration package that iRender has just released, we believe that Daz Studio and iRay users will have the most comfortable, quickest, and most effective rendering time.
