it happens for a long time now... after some work in maya (2012 X64) material previews start to corrupt.


p.s. - this is AGS material...

i occasionally get the same, but running the rhino plugIn.

however it only happens with the default preview scene, others are not affected.
i get some strange blue shine all over with more noise.

have you tried another simple preview scene, like "stage 2"?

I like the default sphere

I like the default sphere

no doubt, the default sphere should be working fine.
i am simply wondering if it is the preview scene itself that is causing the problems.

I find it hard to believe that there's a small timer in the scene that counts down to corruption .... this bug will be hard to detect.
