Hello.
So a short description of the problem. We have VDB files from Houdini smoke simulation, we put them into scene(quite simple few forestpacks one simple house, and terrain), if we render only this VDBs from VolumeGrid, everything is ok, but when we add some object we have rendered only 0-1 pass and then 3ds max just silently close. We noticed that VolumeGrid doesn't render with VrayLightMTL, this cause crashes, we have checked our scene no VrayLightMTL was there. So we move forward, I have tried with isolating just a few objects, anyway it cause the crash, materials on this objects was CoronaMTL, than we convert it to VrayMTL and it still just silently die. We have tried put override material, just gray VrayMTL, seems like it start rendering, but anyway a bit unstable, with override material off we are receiving constant crash. It was with Vray 4.20.01. So we have tried reinstall on the older version 4.20.00 seems like start working better, but anyway we have some random crashes, in this version of Vray some not good bags(in 4.20.01 they was fixed) like region rendering and saving in EXR does not saved whole VFB only region that was rendered. Please find attachment with one of the vraylog files that have some error messages, other vraylog files did not have any error messages in it.
