Raytraced shadows and Vray

[jstrob2]

standard raytrace is not supported by vray. No matter if you use fumefx, you should not use it with vray. When i tried to use it I got darker and lighter shadow depending on the network render node.

Excerpt from vray help pages
Shadow types

Raytraced shadows

This shadow type does not work with V-Ray; using it is not recommended as it can lead to artifacts in the image. Use the specific VRayShadows instead.
