As to why VRay GPU is not updating the tyFlow object properly on successive frames, unfortunately you'd have to contact Chaos Group about the issue. Perhaps something is being cached internally on their side and not updating properly within the memory they allocate. tyFlow updates fine for other renders so this seems to be a VRay issue.
I have the exact same problem: When rendering a sequence, the first frame renders fine, but from the second frame on Tyflow is invisible. I am pretty sure it's not vray, because when I switch to the 3ds max scanline renderer, the first frame renders fine and the second frame just crashes, so there is an issue apart from Vray. I am using a very simple birth surface/surface bind + TyMesher, so my setup is very different than the one from the original post here, but the problem while rendering is the same.
It stands out that any individually rendered frame works totally fine, only when rendering a sequence the problem occurs. So it makes me think it has something to do with how follow-up-frames receive the TyFlow data as opposed to a single frame.
Any ideas?
