Keyframe Mental Ray Opacity

_Swerve_ · May 2014

When every I try and key even a single frame on a Mental Ray material in Maya 2012 it turns solid black. All I need is a very simple fade out over a few frames.

Does anyone know if I am doing something wrong? Or a good work around?

Pretty sure you can keyframe the 'visibility' channel on an object, you could try animating that from 1 to 0 over time.
