In this blog, we’ll explore what MPFB 2 is all about — its key features, how to set it up, and why it could be a valuable addition to your rendering and character creation workflow in Blender. 

Let’s discover with iRender!

As we all know, Blender is a popular software in the 3D artist community. Blender is an open-source software developed to support the creation and processing of 3D graphics. 

MPFB stands for MakeHuman Plugin for Blender. This plugin supports the connection between MakeHuman (3D character modeling) and Blender (3D design and rendering software). MPFB helps users easily transfer models from MakeHuman to Blender for editing or animation.

Its features include:

• • • One-click-create a humanoid mesh
    • Parametric modeling of body features
    • Automatic rigging with a choice from several different rigs
    • Support for Rigify
    • Rigging with both IK and FK modes
    • Procedural skin material
    • Procedural eyes material
    • Asset library with support for clothes, body parts and materials

MPFB is developed by the MakeHuman Community, and it is fully compatible with all MakeHuman assets.

MPFB 2 is the latest version of the plugin that connects MakeHuman and Blender. It is completely rewritten compared to the old MPFB to bring a smoother experience. MPFB 2 is not just a tool to “import characters into Blender” but a complete set of tools for creating, editing, and rendering characters right in Blender.

Some highlights of MPFB 2:

• • • Quick Import: It allows you to create characters directly inside Blender without needing to export files from MakeHuman. You can generate a new character with just a few clicks using the “New Human” option in the MPFB interface. If you already have a MakeHuman (.mhm) file, you can open it directly in Blender—no need to export as .obj or .dae.
    • Preserves Rig (Bones): MPFB 2 supports automatic rigging with several options, including Rigify, Blender’s advanced rigging system. You can add a Rigify meta-rig and generate a full rig for your character. The rig supports both IK and FK, along with helpers for hands, feet, eyes, etc.
    • Advanced Materials and Textures: Including procedural materials for skin and eyes, MPFB 2 allows it to generate high-quality shaders compatible with both Eevee and Cycles. This saves a lot of time on material setup and gives realistic render results.
    • Edit Directly in Blender: MPFB 2 lets you edit body shape, clothing, hair, and other character features directly within Blender using parameter controls. Changes are applied in real-time, making it easy to customize your character without going back to MakeHuman.
    • Modular and Extendable: MPFB 2 is designed with a modular, open architecture, making it easy to integrate into larger pipelines or combine with other Blender plugins. It supports asset libraries for clothing, body parts, and materials, and can be extended further via its API.

One important thing to note is that MPFB 2 is compatible with Blender 4.2+. MPFB 2 is still under active development, so if you want access to the latest features (with the fewest bugs), it’s recommended to use the latest Blender version available and always update MPFB 2 from the official GitHub repository, as new releases often include bug fixes and compatibility improvements. If you’re using a Blender version lower than 4.2, MPFB 2 may not function properly or could cause errors.

Octane Render is one of the most powerful GPU-based rendering engines available today, enabling photorealistic rendering with incredible speed and efficiency. Therefore, having the best GPU for Octane Render can significantly impact your workflow and rendering times. In this blog, let’s explore the key factors to consider when selecting a GPU and provide the best GPU recommendations for different needs and budgets in 2025 with iRender!

OctaneRender® is the world’s first and fastest unbiased, spectrally correct GPU render engine, delivering quality and speed unrivaled by any production renderer on the market. Octane can be purchased separately (Octane Standalone) or as a plug-in for a number of DCC programs, including 3ds Max, Maya, and Cinema 4D. 

OctaneRender is a fully GPU-based rendering engine. This means that the video cards (or GPUs) in your system are what impact how long it takes renders to complete rather than the CPU.

A high-end CPU is not necessary for rendering but improves scene-loading times.

Octane Render is optimized for NVIDIA GPUs and relies on CUDA cores for processing. More CUDA cores translate to faster rendering speeds. RTX cores, available in modern NVIDIA GPUs, accelerate ray tracing, making lighting and reflections more realistic in real time. Because OctaneRender relies completely on the GPU for rendering and does not use the CPU (just for scene loading), a more powerful CUDA-enabled NVIDIA GPU (or multiple GPUs) is needed to increase OctaneRender’s rendering performance. Additionally, OctaneRender scales linearly with the CUDA core number within a given GPU architecture. For example, the GTX 690 (3072 CUDA cores) renders twice as fast in OctaneRender as the GTX 680 (1536 CUDA cores). That’s the first factor we need to consider to choose the right GPU for Octane Render. 

Besides, VRAM determines how complex your 3D scenes can be without slowing down performance. High-resolution textures, large-scale environments, and intricate animations demand more VRAM so it plays an indispensable role in rendering.  The minimum VRAM recommended for basic projects is 8GB, while 16GB-24GB is ideal for professionals. 

Octane supports multiple GPUs for even greater performance gains. If you require extreme performance, a multi-GPU setup is worth considering. Unlike most applications that utilize the GPU, OctaneRender scales almost perfectly with multiple cards. In other words, if you use two cards your renders will complete twice as fast as they would with just a single GPU. If you use four cards you will finish rendering four times faster! However, since Octane is using the cards for compute purposes, they do not need to be in SLI mode.

The NVIDIA RTX 5090 is the latest and most powerful GPU for OctaneRender in 2025. The RTX 5090 is perfect for high-end production studios and professionals working on complex 3D scenes, VFX, and 8K rendering, featuring a significant increase in CUDA cores, improved ray tracing capabilities, and enhanced AI-powered rendering.

One of its biggest advantages is its massive VRAM (32GB of GDDR7 VRAM), which allows for seamless handling of large textures, multiple light sources, and detailed geometries without performance drops. Early benchmarks show that it outperforms the RTX 4090 by 40%, making it the ultimate choice for those who demand unmatched speed and efficiency.

The next GPU you can consider is the NVIDIA Geforce RTX 4090. It remains one of the best GPUs for Octane Render even in 2025. With 16,384 CUDA cores and 24GB of GDDR6X VRAM, it provides outstanding performance for 3D artists and professionals. It also helps handle large, high-res textures and complex 3D models without memory issues. This GPU also features Tensor cores for AI acceleration, making AI denoising and upscaling faster, which is especially useful in OctaneRender’s path tracing and global illumination. 

With its solid performance and lower price compared to the RTX 5090, it remains an excellent choice for professionals who need top-tier rendering power but at a slightly lower cost.

The RTX 4080 is a fantastic mid-tier GPU that offers impressive CUDA core performance with less cost. It utilizes 16GB of GDDR6X VRAM, which is ample for most rendering tasks, but where it really shines is in its new architecture that features AI-driven enhancements like DLSS 3 (Deep Learning Super Sampling) for faster real-time rendering. For GPU-based rendering, AI technologies help reduce noise and improve clarity, which means smoother outputs without the need for extra passes. The RTX 4080 is highly optimized for efficient workflows—rendering large assets like environments, props, and complex lighting setups becomes significantly faster compared to older models.

The RTX 3090 is one of the best GPUs for Octane render. It’s still a powerhouse for OctaneRender with its 24GB VRAM, allowing users to handle massive textures and complex geometry. However, the RTX 3090 does not feature some of the AI-driven improvements of newer GPUs, meaning its performance in denoising and AI-based optimizations isn’t as fast as the RTX 4090 or 5090. Despite that, it remains a solid choice for multi-GPU setups, where adding additional RTX 3090s results in linear speedups for complex rendering tasks. 

Let’s see the bar chart below comparing the most popular GPUs.

It’s shown clearly in the chart above that RTX 4090 has the best performance, which is followed by RTX 4080. Moreover, the performance is better when you combine more than a single GPU. Let’s see, a dual RTX 4090/RTX 4080/RTX 3090 has a higher score than a single one. By the way, we can not find an official benchmark on RTX 5090 with Octane Render. However, because of the latest version that NVIDIA released, I believe RTX 5090 is a GPU worth considering for your project.

Also, Octane Render scales well with multiple GPUs, meaning you can combine different NVIDIA cards for faster performance. A dual RTX 4090 setup can outperform even a single high-end workstation GPU, making it a great investment for studios.

And please note that in a multi-GPU configuration, the VRAM doesn’t compound. This means that all GPUs in the setup must be able to hold the entire scene’s data in VRAM. If the scene is too large for the GPU with the least VRAM, it will not render correctly. For example, with an RTX 4080 (16GB VRAM) and RTX 4090 (24GB VRAM) in the same system, the scene must fit into 16GB of VRAM, which could be restrictive for large-scale, memory-intensive scenes.

As we see on the chart, at the peak, with 7 x RTX 4090s, we end up with a 6.9x higher performance than a single RTX 4090. It’s almost linear. That is about as good as you can ask for and really shows off how well OctaneRender can take advantage of multi-GPU configurations.

If you’re working with OctaneRender and looking to cut down your rendering time, iRender is the perfect solution. iRender is a high-performance cloud rendering platform optimized for GPU rendering. It allows artists and studios to harness the full power of multiple GPUs, significantly speeding up Octane rendering tasks.

With support for powerful GPU configurations (up to 8x RTX 4090), iRender gives you the flexibility to scale your workflow and handle even the most complex scenes with ease.

Maxon Redshift is a powerful GPU-accelerated renderer widely used in VFX, motion graphics, architecture, and product visualization. While it provides fast and high-quality rendering, achieving smooth performance requires proper setup and optimization.

Many users face slow renders, noisy outputs, or memory limitations, but these challenges can be overcome with the right techniques. This guide will cover essential tips to help you optimize performance, manage resources, and enhance workflow efficiency in Redshift. In this blog post, let’s explore with iRender.

Render settings play a crucial role in balancing quality and speed. Setting up Redshift correctly ensures you avoid unnecessary slowdowns while maintaining a high level of detail.

✅ Choose the Right Render Mode

Redshift provides two modes:

• Basic Mode: Ideal for beginners or quick renders with minimal customization.
  
• Advanced Mode: Gives full control over sampling, ray tracing, and optimization settings for professional work.

Tip: If you’re experiencing long render times, lower the sample values in basic mode first, then tweak the advanced settings as needed.

✅ Use Adaptive Sampling for Faster Renders

Adaptive sampling automatically reduces noise where needed instead of using a high, fixed sample count across the entire image. This speeds up rendering while maintaining quality in critical areas like shadows, reflections, and fine details.

Since Redshift is GPU-based, its performance depends largely on the graphics card’s memory, processing power, and system configuration.

✅ Utilize Multiple GPUs

If you have multiple GPUs, make sure Redshift is using them efficiently:

• Enable Multi-GPU Rendering in the Redshift settings.
  
• Avoid mixing different GPU models, as it may cause instability.
  
• Ensure adequate VRAM (8GB+ recommended for complex scenes).
  

✅ Optimize VRAM Usage

Large textures, displacement maps, and high-poly models can quickly eat up VRAM, slowing down performance.

• Use Mipmap Textures instead of full-resolution textures.
• Limit displacement subdivisions to essential areas only. 
• Use Proxy Objects (RS Proxies) for high-poly models.

Redshift’s shader system allows for complex material creation, but inefficient textures can significantly slow down renders.

✅ Use the Shader Node Editor for Efficient Material Management

Redshift’s Node Editor lets you build procedural materials, reducing the need for large image textures.

Tip: Instead of using high-resolution bitmaps, use procedural Noise and Gradient nodes to dynamically create textures.

✅ Reduce Texture File Size

Instead of using 4K or 8K textures for every object, downscale textures where possible:

• Diffuse maps: 2K–4K is often enough.
• Bump/Normal maps: Can be reduced to 1K without significant quality loss.
• Use JPG instead of PNG for non-transparent textures to save memory.

✅ Use Area Lights Instead of Point Lights

Point lights cast shadows in all directions, increasing render time. Instead, use area lights with controlled spread for better soft shadows and faster performance.

Tip: Use Portal Lights for interior scenes with windows to improve global illumination.

✅ Optimize Shadow Samples to Reduce Noise

Too many shadow samples increase render time, while too few create noise.

• Enable or disable shadow casting:

• Transparency:

This setting determines the transparency of shadows created by the light source. Lower values result in darker shadows, with a default setting of 0 producing entirely black shadows. Conversely, a value of 1 eliminates shadows.

The example below illustrates how the shadow transparency of a fully opaque sphere can be adjusted using this light parameter.

• Softness:

This setting controls the softness of shadow edges for non-area lights. A value of 0 results in sharp, well-defined shadows, while increasing the value creates progressively softer shadow edges.

By applying these essential Redshift optimization tips, you can improve render speed, reduce noise, and make better use of your hardware. The key to working smoothly with Redshift is balancing quality and performance, keeping your workflow efficient, and continuously learning from experts.

Whether you’re working on realistic VFX, architectural visualization, or motion graphics, mastering these techniques will boost your efficiency and rendering quality.

Realistic lighting is one of the most critical aspects of creating immersive and visually stunning 3D graphics. Achieving a realistic interplay of light and shadow can distinguish a picture from being genuine in video games, computer-generated imagery (CGI) movies, and architectural visualization. Ambient Occlusion (AO) and Global Illumination (GI) are two crucial methods that support this realism.

In this article, we’ll explore how GI and AO work, their differences, and how they complement each other in 3D rendering. Let’s dive deeper into it with iRender!

A basic lighting approach called Global Illumination replicates how light interacts with real-world things in a digital setting.  In order to produce more lifelike virtual environments, global illumination (GI) enables light to bounce, refract, and diffuse across a scene. 

• • • When light hits a surface, part of it is absorbed while the rest is reflected, illuminating nearby surfaces.
    • This process creates effects like color bleeding (where colors from one object reflect onto another) and soft shadows (caused by indirect lighting).

• Sunlight in a Room: When sunlight enters through a window, it doesn’t just light up the floor directly; it also bounces off walls, furniture, and other surfaces, softly illuminating the entire room.
• Color Reflection on Walls: If you place a red object near a white wall, you might notice a faint red tint on the wall. This happens because light bounces off the red object and carries some of its color.
• Soft Shadows Under a Tree: On a sunny day, the shadows under a tree aren’t completely black. Light bounces off the ground, leaves, and sky, filling in some of the darkness with soft, natural lighting.

• Radiosity: Computes diffuse interreflections by dividing a scene into smaller elements and distributing light energy.
• Photon Mapping: This method simulates the journey of photons (light particles) through a scene. Emitted from light sources, photons bounce around and interact with surfaces.
• Ray Tracing (Path Tracing): Shoots rays from the camera to simulate light bouncing in a realistic way.

Ambient Occlusion (AO) is a shading technique that enhances contrast and depth by darkening areas where ambient light is blocked, such as crevices and object intersections. Unlike GI, AO does not simulate real light behavior but helps create a more realistic perception of depth.

• AO calculates how much ambient light reaches a surface. Areas in tight spaces receive less light and appear darker.
• This effect improves realism by adding subtle shadows in occluded areas.

• Corners of a Room: In a naturally lit room, the corners where two walls meet often appear darker than the middle of the walls because less indirect light reaches these areas.
• Underneath Furniture: The area under a table or sofa is usually darker than the surroundings, even in a well-lit room.
• Folds in Fabric & Clothing: In real life, the creases in a shirt or folds in curtains appear darker because they trap ambient light. AO enhances these small details in character models and fabric simulations.

• Screen Space Ambient Occlusion (SSAO): Uses depth buffer data to approximate AO in real-time.
• Ray-Traced Ambient Occlusion (RTAO): Uses ray tracing for more accurate AO calculations.

• Both of these techniques are used to enhance realism and create the natural feeling of lighting in a 3D scene. Without AO or GI, the scene would look flat and lack depth.
• Both affect shadows. AO helps darken occluded areas to create soft local shadows, and GI allows handling indirect lighting, creating more natural soft shadows.
• Combine them for better effects. AO does not replace GI but can be used as a supplement to enhance contrast.

Although they both improve realism in 3D graphics, Ambient Occlusion (AO) and Global Illumination (GI) have different uses.  By calculating indirect light bounces, GI replicates real-world lighting, producing accurate color bleeding and soft, lifelike shadows.  AO, on the other hand, improves shading by darkening regions like corners and creases where light is obstructed, rather than mimicking real light.  

While AO is lightweight and frequently used in games and lightweight 3D models to provide depth without incurring excessive computational costs, GI’s complexity has a significant performance impact, making it perfect for movies, architectural visualization, and AAA games.

Global Illumination (GI) simulates how light bounces off surfaces, creating soft, natural lighting that reacts dynamically with the environment. This technique enhances realism by capturing the indirect light that illuminates shadowed areas, much like how light behaves in the real world.

On the other hand, Ambient Occlusion (AO) is a shading method that darkens areas where light struggles to reach, such as corners, crevices, and under objects. While it doesn’t simulate light bouncing, AO helps to enhance depth perception by emphasizing soft shadows in occluded areas.

Both Global Illumination and Ambient Occlusion play crucial roles in creating realistic 3D scenes. While GI is essential for simulating light behavior, AO is a valuable addition for enhancing shadows and depth. The combination of both techniques—especially with modern GPU acceleration—allows for highly immersive visuals in games and CGI.

Both Global Illumination (GI) and Ambient Occlusion (AO) play an important role in creating realistic images in 3D graphics. Despite their differences in functionality, these two techniques are often used together to optimize image quality while ensuring performance.

However, calculating GI and AO, especially when using Path Tracing or Ray-Traced AO, requires powerful hardware with high processing performance. This is where iRender becomes an ideal solution. With a powerful GPU system on the cloud computing platform, iRender helps 3D artists, architects and game developers render faster, optimizing time and costs.

Most of the 3D graphics software today support AO and GI, such as Blender, Maya, 3ds Max, Cinema 4D, Unreal Engine… iRender offers the most powerful RTX 4090 configuration packages on the market, all equipped with AMD RyzenTM ThreadripperTM PRO 3955WX @ 3.9 – 4.2GHz and AMD Ryzen™ Threadripper™ PRO 5975WX @ 3.6 – 4.5GHz processors, 256GB RAM and 2TB NVMe SSD storage.

iRender – Happy Rendering!

There are a lot of reasons why your Redshift can render so slow, slower than you expected. It could come from your low-end hardware, the scene optimization, the effects or sometimes render settings. The reasons are various and it’s no end if we talk about them. Let’s talk about something more helpful, such as how to troubleshoot Redshift rendering slow. This article collects some common solutions we have used to help our users on iRender render farm.

NVIDIA Studio Drivers undergo extensive testing against multi-app creator workflows and multiple revisions of the top creative applications, which help you to achieve the best performance and reliability when working with those apps.

Sometimes, slow render in Redshift is caused by old studio driver, and updating to a latest version will help.

On iRender remote machine, we always update to the latest driver version. However, if we haven’t updated on time, you can always come to X drive of the remote machine > 11.NVIDIA RTX 4090 DRIVER > Studio > take the latest driver to the remote desktop and install.

It will take some minutes to restart the machine, and then you can connect again. Don’t shutdown the machine while it’s updating. After it’s done, you can start the render again.

You should always remember to work/install/set output path on the iRender remote desktop or C drive, not inside Z/Y drives.

Z/Y drives are network drives for transferring files only. Working there is not stable and could cause slow rendering or even crashing.

Sometimes turning on/off hardware acceleration on the remote machine can help you render faster. To do so, follow these instructions:

On Windows 10, you download the .rdp file to your local PC > right-click the .rdp file and choose Edit > on the Remote Desktop Connection tab, choose Display > drag the slider to the left and to the right to change the hardware acceleration > click Connect. The password for .rdp file is your iRender account password.

On Windows 11, you right-click the desktop > Display Settings > Graphics > Change default graphics settings > click the toggle switch below “Hardware-accelerated GPU scheduling.” Then you start your render again to see if it works.

To optimize rendering speed, please configure the render setting as follows:

• • • • Increase Bucket size to the max
      • If the Irradiance Point Cloud Screen Radius is used, increase it to maximum.

Hybrid Rendering uses both the CPU and GPU to render a scene. You can enable or disable Hybrid Rendering in the Redshift settings here:

Hybrid Rendering does not always cause slower rendering. For simple scenes, this setting may work well, depending on CPU performance. However, older or less powerful CPUs may render more slowly than expected.

For more complex scenes that require more power, the CPU can become a bottleneck. In such cases, the GPU may finish its tasks quickly, but the render will be delayed while waiting for the CPU to complete its portion. If this happens, it is best to disable Hybrid Rendering for better performance.

Redshift or any 3D software requires strong hardware. Maybe your hardware or the remote machine you use on iRender render farm is not strong enough. You can always check another server package and try rendering to see if it’s faster.

To do so, without losing your installed software and data, you can shutdown the remote machine > choose “change package” feature. All your software and data will remain. Remember that your machine must finish shutting down, then you can choose “change package”.
