RenderMan - User Interface and Experience
User Interface and Experience
The user interface and experience of RenderMan, developed by Pixar, are crafted with a strong focus on artist-centric tools and seamless integration with various 3D applications.
Integration and Compatibility
RenderMan Bridge Tools are custom-made for each supported 3D application, including Autodesk Maya, Foundry’s Katana, and SideFX Houdini. These tools are developed in collaboration with the application’s developers, ensuring they make the most efficient use of the application’s interface. This integration allows artists to work within their familiar workflows, enhancing productivity and creativity.
Interactive Rendering
One of the standout features of RenderMan is its capability for live rendering at every stage of the pipeline. This allows for immediate visual feedback as artists edit geometry, hair, simulations, animation, shaders, and lights. The interactive rendering feature enables quick adjustments, such as tweaking the thickness of a glass for perfect refraction or seeing how character wrinkles react to subsurface scattering in real-time. This real-time feedback significantly speeds up the decision-making process and improves overall workflow efficiency.
Preset Browser and Asset Sharing
RenderMan includes a Preset Browser that provides an extensive library of materials and lighting presets. This feature allows artists to access and share assets easily between different 3D content creation tools, streamlining the workflow and facilitating collaboration.
Artist Tools and Workflows
Each bridge product for different 3D applications has been rewritten to provide an optimal user experience for always-on live rendering. The Image Tool (IT) has been overhauled to deliver the fastest interactivity possible, and the time to the first pixel is much faster due to direct API calls into the render engine. This eliminates the need to export scene data to disk or wait for RIB generation, making the rendering process more fluid and interactive.
Stylized Looks and Customization
RenderMan offers a Stylized Looks framework that allows artists to create non-photorealistic renders, such as animatable pen and ink illustrations or toon shading. The latest versions of RenderMan, like version 25 and 26, have enhanced this feature with more creative controls, illustrative lighting, and a cleaner user interface. Additionally, RenderMan retains its traditional customizability, allowing experts to develop unique looks or pipelines using custom plug-ins or scriptable elements.

RenderMan supports the industry-standard ACES color management system, ensuring consistent and predictable color output. It also includes an interactive version of the advanced machine learning Denoiser from Disney Research, which helps artists see converged results more quickly during interactive renders.
Performance and Scalability
RenderMan is optimized for high-performance interactive rendering, leveraging Pixar’s next-generation renderer, RenderMan XPU, which uses GPU CPU hybrid technology for fast rendering speeds. The system is multi-threaded and GPU-ready, providing fast look-development workflows and scalability on machines with many cores.
Conclusion
In summary, RenderMan’s user interface is designed to be highly interactive, intuitive, and integrated with popular 3D applications. It offers a seamless and efficient workflow, immediate visual feedback, and extensive customization options, making it a powerful tool for artists and studios alike.
RenderMan - Key Features and Functionality
RenderMan Overview
RenderMan, developed by Pixar, is a versatile and powerful rendering engine that offers a wide range of features and functionalities, particularly enhanced by its integration of AI and advanced technologies. Here are the key features and how they work:
Physically-Based Rendering
RenderMan is optimized for physically-based rendering, which allows it to deliver highly realistic lighting and materials with minimal setup. This includes full support for multi-bounce ray-traced global illumination and ray-traced subsurface scattering, making it ideal for creating photorealistic images.
Interactive Denoiser
RenderMan features an advanced machine learning-powered denoiser, which was introduced in version 25 and further enhanced in version 26. This denoiser can be used interactively in certain applications like Katana and Blender, allowing artists to remove noise from the rendering process in real-time. While it’s not yet as effective as the full offline denoiser, it significantly aids in refining images during the testing and production stages.
Adaptive Sampling
RenderMan includes adaptive sampling, which directs samples to areas of the image where they are most needed. This not only improves the quality of the rendered image but can also speed up the rendering process by optimizing resource usage.
XPU Support
RenderMan XPU (eXtended Processing Unit) enhances performance by leveraging both CPU and GPU resources. This results in faster rendering times, especially when dealing with complex scenes involving many instances and textures. The XPU support also improves the efficiency of motion blur and depth-of-field effects.
Motion Blur and Depth-of-Field
RenderMan can realistically simulate the behavior of real-world cameras by incorporating motion blur and depth-of-field effects. Motion blur helps in creating a natural look for moving objects, while depth-of-field allows for control over the focal length, aperture diameter, and focal distance to achieve realistic blurring of backgrounds.
Checkpointing
Checkpointing is a feature that allows RenderMan to resume interrupted renders, which is particularly useful for refining images over multiple passes. This feature enables daily reviews and more iterations of animated sequences without having to wait for the final frame.
MaterialX and Pixar Surface
RenderMan includes MaterialX Lama, a state-of-the-art material layering system developed in collaboration with Industrial Light & Magic. This system, along with Pixar Surface, provides extensive creative options for shading artists to create a wide range of materials, from glass to subtle skin textures.
Secondary Passes and Compositing
RenderMan supports breaking down visual effects into secondary passes for compositing, including DeepEXR and Cryptomatte support. Artists can write various elements of a render (such as SSS, Diffuse, Shadows, Z-Depth, Object IDs, Per-Light AOVs) into multiple formats, making the compositing process more efficient and artist-friendly.
Stylized Looks
RenderMan version 26 introduces an expanded Stylized Control system, which enhances non-photorealistic stylized rendering. This includes new ways to express line work, hatching, and toon effects, making it a go-to tool for artists working in toon-style animation.
Integrators and Light Transport
RenderMan provides several integrators, including Pixar’s own integrator, Pixar Unified, which has been used in numerous Pixar productions. The integrator system allows for creative control over light transport and gives development teams the freedom to experiment with custom integrators and materials.
Network Rendering with Tractor
RenderMan comes with Tractor, a modern network rendering solution that is widely used in the VFX industry. Tractor allows for efficient distributed rendering, making it easier to manage and scale rendering tasks across multiple machines.
Extensive Plugin Support
RenderMan integrates seamlessly with various 3D applications such as Autodesk Maya, The Foundry Katana, SideFX Houdini/Solaris, and Blender. It also supports leading plugins like Xgen, Unreal Shave and Haircut, and Peregrine Labs’ Yeti, ensuring compatibility and flexibility in different production pipelines.
