Renders show black boxes randomly (empty buckets).
I've read many many posts (not only specific to Vray for Rhino) regarding the black squares appearing in the renderings and most of them seem to be related to Distributed rendering when slave machines can't find textures, etc. This is not my case as I use a single machine. Also I doubt that is a RAM problem, I increased the RAM allocated to Rhino to the max and Vray's "Dynamic memory limit" to 14400 (I have 16gb of ram).
After many hours of trying different settings, it seems to be a problem related to the GI primary rays method chosen:
It doesn't happen if I set the primary rays to brute force (with default of 8 subdivs and 3 bounces). With the other methods (irradiance map, Photon map or none the black squares appear. My preferred method would be irradiance map.
The secondary rays are set to light cache.
BTW disabling GI altogether solves the problem, so it's definitely GI related. (but crappy and shadowy lighting as a result, of course)
The rendering is relatively small 800x600 and not a particularely large scene.
Any help would be appreciated.
Thank you
