**Note:**
|
|
This plugin is not representative of actual workflows in the application. The
|
|
intended use is for quick comparisons with Renderman's interpolation settings.
|
|
|
|
Usage
|
|
=====
|
|
|
|
Once the plugin is loaded in Maya:
|
|
- Select a poly mesh
|
|
- Polygons -> Edit Mesh -> OSD Subdivide Meshes
