Download RenderMan for Maya: Enhance Your Animation Workflow

RenderMan is a powerful rendering software used in various industries, including film, television, and video games. The latest release of RenderMan, version 25.1, brings several improvements and bug fixes to the table. In this article, we will explore the key features and enhancements introduced in RenderMan 25.1, especially for Maya users.

Spherical Projection Dicing Oracle

One of the notable additions in RenderMan 25.1 is the spherical projection dicing oracle. This strategy can be used as a primary dicing method when rendering multiple instances of geometry with a camera flying through them. The oracle ignores offscreen dicing controls and does not change its behavior when an instance moves out of view. Additionally, it avoids overdicing geometry near the camera, resulting in more efficient rendering.

Geometry Improvements

Several improvements have been made to geometry processing in RenderMan 25.1. For instance, the curve minwidth feature can now expand curve widths without restriction to achieve the desired screen-space size. This enhancement ensures that curves are rendered accurately and consistently.

Another significant change is the restoration of the spherical projection dicing oracle after a long absence. This feature allows for more efficient rendering of complex scenes with multiple instances of geometry.

BxDFs Enhancements

The BxDFs (Bidirectional Distribution Function) in RenderMan 25.1 have also seen some improvements. An error in the followTopology values for PxrSurface diffusion subsurface scattering has been fixed, and LamaIridescence incidentAngle_Interpolation and targetHue_Interpolation can now be specified with a minimum of two knots or a constant value.

LamaSurface: Presence/Opacity Caching

The LamaSurface feature now includes an option to enable presence/opacity caching. This enhancement allows artists to optimize their scenes for better performance in Maya.

Other Enhancements and Bug Fixes

RenderMan 25.1 also includes several other enhancements and bug fixes. These include:

* Support for Python 3.10

* Improved built-in listeners for stats, which expand environment variables for file names found in the stats.ini configuration file

* Allow PxrPrimvar to better constant fold space transformations, giving better performance in RIS and better correctness in XPU

RenderMan 25.1 is a significant update that provides several improvements and bug fixes to the rendering software. With its enhanced geometry processing capabilities, BxDFs enhancements, and other features, this release promises to enhance your animation workflow, especially when used with Maya. If you're already using RenderMan, we recommend upgrading to the latest version for better performance, accuracy, and creative control.
