View Full Version : Rendering vray displacement

so when I render displacement through vray, I get some weird white artifacts (sort of like nan boxes with mental ray, but they are white.) I also get some greenish hues on the fringes of the model (even though the diffuse and spec are black and white respectively)

any ideas?

A picture of the problem might help us help you. I've used displacement without too many problems.

Artifacts can happen where the displacement pulls the surface apart at sharp edges (like the edges of an unbevelled cube for example). You can check the "Keep continuity" option to try and minimize this, but sometimes it is better to actually add a bevel to round off the problem edge and make it easier to displace in a continuous fashion.
