Vray 3.6 + motion blur + forest pack - 'tearing' mesh

[busseynova]

I wondered if anyone's seem this before, and knows where I might be best starting my troubleshooting? Namely the holes within the mesh on the faster moving body parts.

I'm using Forest Pack Pro to scatter 3D animated characters over a scene. I'm using Vray 3.6, physical camera, LC & BF, 3DS 2019. The material is a Vray material with Forest Colour maps for the diffuse (and a few other things)

Any pointers appreciated!

Best you send the scene to support@chaosgroup.com so we can take a more in-depth look. Mention this thread as well.

I think it was a result of FP not being compatible with motion blur. when I changed them to instances problem solved.
