Known Limitations

RenderMan for Maya

• Deselecting "Receive Shadows" does not work.
• Light Linking volumes is not currently supported
• The Holdout shelf button fails to operate, use the shape node render stat setting Maya to create the holdout object.
• Creating a mesh light from existing geometry during IPR will duplicate the geometry in-render. Restart the render to remove the duplicate.

• Xgen will not reflect changes in the Collection
