vray motion blur - jiriwolf - 09-21-2019

Hello i have some problem with Vray motion blur (maybe its not just vray) im using quite simple flow where i need to delete some older particle (but i did test without deleting them and its same) If i export to alembic there is no motion vectors so its not the way for me.

So here is single image with motion blur that works (it happend if i render just one image from timeline 1-500) it also works when i render animation then first frame from sequence works fine. Confused

here's example for the other images from sequence if i render animation (motion blur looks weird)

in the attachment is also MAX2019 scene for debugging (there is GPU vray settings now but i did test CPU too and it didnt work also)
Thank you for any help!

I've been having similar issues using vray gpu as well. Also rendering snow fall. Every hundred or so frames, everything glitches and appears as if vertices exploded.

I was able to fix the issue by raising motion blur samples and/or removing the camera cull node for affected frames.

Vray GPU is not a supported rendering mode, so you won't get proper motion blur unless your maintain the same verts/faces between frames.

Hi, is this still valid ?

I ask because this is an old thread and i found no article about incompatibility with Vray GPU but i'm faceing a lot of issues with motionblur.

I'm pretty new to ty flow and don't know if they are caused by tyflow or vray or some incompatibility or my fault.

Thanks
