This release provides you with bug fixes and minor enhancements. Shaders are discoverable if they are found in a search path and (for non-OSL shaders) have an associated Args file. RenderMan version 25.1 builds on RenderMan 25.0, which provided major upgrades to look development and batch rendering, with many tools that improve artist workflows and complement the creative process. Shader Discoveryĭuring startup RenderMan for Katana will automatically load all "discoverable" shaders. The challenges were to create custom procedural shading solutions for their environments, so they wouldnt have to manually model & texture everything. You can direct the render log output to another location if necessary using the following environment variable: RFK_REDIRECT_OUTPUT You can also use RFK_OVERRIDE_RENDER_ACTION When set, this overrides the default processing for render outputs to always render directly to the renderLocation specified in the RenderOutputDefine node without any copying or processing from Katana.

These environment variables replace rather than append to the default paths, so you will need to include the default paths as well. In order to use the PrmanRender node, you need to have Pixars PhotoRealistic RenderMan Pro Server 20, or earlier, installed and licensed on your machine.
If additional search paths are needed then you will need to set up the RMAN_SHADERPATH and/or RMAN_RIXPLUGINPATH environment variables to include your specific paths. Default shader search paths for RenderMan match the default paths in the rendermn.ini file. With latlong texture maps the environment sphere is mapped to a the texture with the maps S coordinate representing longitude (from 0 to 360 degrees) and the T.
