When the value of Geometry samples is greater than 2 in the vray gpu mode, the moving object disappears

I uploaded the project. This problem will occur when rendering the animation, but it will not occur in a single frame, as shown in the picture

Hi @123456_1 , this seems to be bug on our side (which I logged for fixing as VC4D-1616). In the meantime, there are two workarounds you can use render the object:
1. You can try to use the bucket image sampler
2. You can try to force dynamic geometry usage (see the attached image)

Thank you for your solution
