Hello! I'm running the latest build of V-ray 5 for Houdini 18.5.408 on a Windows 10 computer with an RTX 2070 Super graphics card.
I'm rendering a very simple/light scene featuring particles that were cached to/are being read from disk--not many, only about 800K of them. When rendering using RTX mode, the particles will disappear on the occasional frame, but reappear on the next frame. The frames where they disappear are consistent, so re-rendering that frame doesn't kick it back into action. However, if I render using CPU the particles are visible in those frames. Is this just a shortcoming of GPU rendering, and for particles it's best to stick with CPU? (If it is relevant, while it's rendering I will, after a while, get the "num of samples per thread reduced" message, with the number getting smaller for each frame, and it tends to stop rendering after 80 frames. I'd call that a crash, except that restarting the render starting at frame 81 works just fine.) I have a basic V-ray material applied to them (not the point particle).
Thanks for any guidance!
