Hi : ) I'll get this out of the way first. I'm using a Mac with Maya 2012 x64 SP2 with V-Ray 3.1
This is the problem:
Using Light cache as 2nd GI + Motion blur + Use retrace threshold + light colored material on any deforming mesh = Some frame renders of this animation will crash.
This is what happens when I try to render an animation with a moving character. I've been testing for over a week now. Trying all kinds of different render and material settings, on different meshes, lights and a new cameras. And in the end I tested with hiding everything in the scene except a mesh that seems to cause Maya to crash during the render process of some of the frames. It's not the mesh either that is causing this because any light colored material on different deforming meshes seem to be able to make it crash. But these specific frame renders keep crashing with motion blur on (physical camera node), BF + 2nd GI engine Light cache (advanced: retrace: on) and a deforming mesh with material being too light. A light colored material on a deforming mesh that is above 80% white will already cause these frames to crash during a render. The funny thing is the same situation in the other frames of this animation (with just a little different deformation or movement), will render just fine.
It will render fine as well if I change just one of these (even just using a darker texture). But I sort of need motion blur, retrace threshold, and the light colored materials here. I'd be happy to know if these problems seem familiar to someone and if so if there is a solution to it.
Or what I've been looking into just now as alternative, maybe there is an effective way to render it without using Light cache? Only Brute force seems to slow, but is it useful to use it as 2nd Engine with Irradiance map maybe? I'd like to know because these engines have not been causing any crashes.
Edit 1: I'm thinking about just leaving retrace threshold off now. In some frames it looks actually better.
Edit 2: Actually I'm still having problems without retrace, so if there are any clues to solving this please let me know, it would help a lot.
