We got buckets in DR mode on materials that uses interpolation for reflection. We got around it in simply disable interpolation mode.
GI=Irrmap, Vray1.5sp3, 32bit WinXP, 4 Quadcore Clients
As you can see on the image, every other mats with/without reflections make no problems.
I’ve been getting this also on occasion, but only on my workstation, not my coworkers, i haven’t had a chance to debug whats going on yet though. I did note that it happens when using DR, and it is my personal machine that is causing the artifacts, but does NOT happen when i render locally without using DR.
I’m on max 2009 x64 in xp64
And to make it even more fun to track down, it doesn’t appear to happen in all scenes!
