Modern Physically-Based Rendering

RenderMan offers a combination of unbiased and biased rendering techniques which provide both accuracy and technical efficiency

State of the Art

RenderMan version 24 is a landmark release with innovation in look-development and industry collaborations, making it the most flexible, powerful, and reliable rendering engine for cinematic imagery.

The RIS technology in RenderMan has matured and evolved into a highly-optimized framework for production needs and RenderMan 24 expands this toolset even further with new Stylized Looks for non-photorealistic renders, a new layered material system developed at Industrial Light & Magic, and an all new live statistics system.

With the launch of Pixar's hybrid CPU + GPU renderer, RenderMan XPU™, artists can look-develop faster than ever, giving pipelines a suite of exceptional tools for advancing look-development workflows for feature film animation and VFX.

Artistic

RenderMan provides major upgrades to Look Development, with many tools that improve artist workflows and complement the creative process, including the highly anticipated RenderMan XPU™.

Today there are many options for integrating RenderMan into VFX pipelines, including solutions from Pixar for Autodesk Maya, The Foundry KATANA, SideFX Houdini/Solaris, and an all new plugin for Blender. For lighting and look development, RenderMan offers a state-of-the-art system for interactive rendering that is capable of dramatically increasing the throughput of production scenes while allowing artists to focus on their art.

This intuitive system for creating photoreal and stylized looks, allows artists to create the most versatile and unique imagery conceivable.


Production-Ready Light Transport

Uni-Directional Path Tracer

The most used integrator, ideal for outdoor lighting and large direct light sources, this industry standard unidirectional path tracer combines samples from materials at hit points with light samples to estimate direct lighting, then spawns additional rays to handle indirect lighting.

The path tracer ships with source code for further customization.

Bi-Directional Path Tracer

For scenes problematic for unidirectional path tracing, the bi-directional Path Tracer, also called VCM integrator, can save the day. In addition to tracing paths from the camera, bi-directional path tracing also sends rays from light sources and then connects them. VCM can resolve complicated indirect paths and caustic effects that may be prohibitively slow to converge with unidirectional path tracing. Ideal for rendering interiors.

Pixar Unified

Pixar Unified offers both unidirectional and bidirectional path tracing which can be controlled on a per-light basis, so you get the best of both. It also delivers state-of-the-art light path guiding based on work from Disney Research for computer learning. The Pixar Unified integrator also contains functionality for quickly resolving caustic paths, a technique called Manifold Next Event Estimation, allowing caustic paths to resolve much quicker.

"As we advance our animation pipeline, we look forward to using the new lookdev tools in RenderMan 24."

-Paul Baaske, Workflow Architect, DNEG Feature Animation

Custom Development

RenderMan's robust APIs provide all the necessary tools for studios to write their own integrators and materials, allowing development teams creative and non-destructive freedom to experiment with cutting-edge technology.

Out of This World Innovation

Developed specifically for animation and VFX, this release is continuing to raise the bar for look development and industry collaborations.

The Future is Here!

RenderMan features modernizations to the look development process featuring high-performance interactive rendering, along with updated bridges for Autodesk Maya, Foundry’s Katana, SideFX Houdini/Solaris, and an all new plugin for Blender.

RenderMan now provides even greater speed during the look-dev process thanks to XPU™ and expands it in RIS thanks to Lama, Stylized Looks, and many other innovations.

Open Standards

In 1988 RenderMan established an open standard to describe 3D data: the RenderMan Interface Specification (the RISpec). Since then, Pixar has continuously developed RenderMan to push the limits of the core technology while helping to adopt and promote new standards for the creation of high-end visual effects and animation. In today's continued efforts, RenderMan supports many open standards, among them: Alembic, OpenColorIO, OpenEXR, OpenSubdiv, OpenVDB, OSL, SeExpr, Ptex, UDIM, USD

Cross Platform

RenderMan and all its plug-ins are made for the three main operating systems: Linux, OSX, and Windows.
