I've only seen this happening when switching between passes that use different
renderers (e.g. from a Vray pas back to a MRay pass). It always works ok going
from MRay to Vray, but switching back to the pass using MRay gives me the
behavior you describe. Closing the RR, saving the scene, and reopening the RR
usually solves it for me in 80% of the cases.
There is a short thread about this on the Vray4Softimage forum:
http://www.chaosgroup.com/forums/vbulletin/showthread.php?70487-Some-build-22370-issues
The bottom line as described by Kamen Lilov:
"This is not really a VRay problem; we can - and do - handle the case where we become
the current pass renderer and force a repaint (by touching the scene). This is why the
somethingElse -> VRay direction works. Not sure how we can place a workaround for the
opposite direction though. Would be best if AD fixed this."
Every so often my render region just quits rendering. I can open and close
it or move the camera and it just keeps whatever pixels were last rendered.
The only fix is to restart the whole app. Does anyone else have this issue
or have a way to reboot the region?
