I tried render diagnostics, it came up with many things that have keyed visibility.
I don't know if that's the problem, though! Some of my lights also have keyed visibility, but is that really the issue?
Every time I go to batch render, it says "Rendering..." then it tells me "Render completed". I turn off motion blur and it's fine. What do I do? Is keyed visibility really the problem, or is something else at play, and why?
I'm using Mental Ray for Maya 2009.
