Autodesk releases its first Hotfix for Maya 2011. Download it from the Autodesk website.
The Hotfix addresses these limitations:
- Maya crashes when navigating through menus on Mac 64?bit.
- Viewport renderer plugins do not work
- mental images Material no longer respects refraction limit
- mental images Material Ambient Occlusion color bleed stops Final Gather bounces
Autodesk is recommending an uninstall of Maya 2011 before installing the hotfix 1, and the installer is not a fix or a patch, it is 1.3gb – the entire application.
