Yeti

Guerilla Render can render the Yeti's procedural geometries.

Installation

Linux

Guerilla uses the pgYetiPrmanRender DSO and the pgYetiCacheInfo application. The Yeti bin directory should be added to the LD_LIBRARY_PATH variable before running "guerilla" or "render".

Windows

Guerilla uses the pgYetiPrmanRender DLL and the pgYetiCacheInfo application. The Yeti bin directory should be added to the PATH variable before running "guerilla" or "render". It should be the case on a standard Yeti installation.

Export from Maya in a Yeti node (default)

In this mode, the Yeti fur files must be cached. A Yeti node will be created in Guerilla, referencing your Yeti cache, with controls on density, width and length. No RIB files are needed in this mode.

To use this mode, make sure the Yeti Nodes as RibBox checkbox is turned off in the Guerilla > Export project settings. Using the Yeti node, you have to set GuerillaNode/Shutter Open and GuerillaNode/Shutter Close to 0.0,0.5.

Export from Maya in RibBox

During the GuerillaExport command, the Guerilla plug-in will write ".rib" files in a folder named "projectname.rib" side by side with the Guerilla project. Those rib files contain the procedural rendering commands that reference the .fur files. The exported Guerilla project includes a RibBox node for every Yeti object that renders those rib files.

Without Yeti cache

During the GuerillaExport command, the Guerilla plug-in will generate the Yeti ".fur" files. Those fur files will be referenced by Guerilla.

With Yeti cache

The fur files are not generated. The previously cached fur files will be referenced in Guerilla.

To use this mode, turn on the Yeti Nodes as RibBox checkbox in the Guerilla > Export project settings. Using Yeti cache, you have to set GuerillaNode/Shutter Open and GuerillaNode/Shutter Close to 0.0,0.5.

Yeti Shader Attributes

The curve shader is fully functional with the Yeti curves. The surface texture coordinates "st", the curve ids and the surface normal are handled like any other curves in Guerilla.
