Problem while animating HQ grass

(1/1)

JR4646:
Hi,

We have setup an architectural environment using Forest Pack HQ grass1. The render look just perfect in static using Vray. But the moment we trying animating the same, i mean just some camera movement, there seems to be some shadow on the grass and trees that seem flickering and thus messing up the output.

Could you please help us with some solution.  I have attached some sample TGAs for reference.

Thanks,

Anil

This is a common problem when rendering high detailed objects in VRay. Unfortunately it seems doesn't exist a simple fix, because there are multiple threads in the ChaosGroup forum regarding this issue.
