hi
i use a mental ray 1.5 for maya 4.5
i have a problem whit shadow . in my sence when camera is moving shadows in some area become flicker . and another problem is that the final image have a effect like grain maybe its for the low sample in global illum and final gather .this are my seting for my scenes . can anyone tell me what do i must to do? thanks a lot
