Contour render bug

[max_sterry]

I'm getting these weird rendering artifacts. The material is generic white with a contour. It renders normally when I turn off the contour. There's no duplicated geometry.

Any ideas how to fix this?

Thanks in advance.

EDIT: Don't know what caused the bug, but I found a solution. I reduced the normal and overlap threshold and that fixed it.

Render artefacts can be caused by a to large distance of the scene from the 0,0,0 origin. Moving the scene to 0,0,0 could help.

Hello max_sterry ,

I am able to reproduce the issue only with overlapping geometries.
Could you please send us the scene file or a selected part of it, which exhibits the issue? You can do this by packing your project from the Rhino menu > V-Ray > Pack Project and share the resulting archive through https://support.chaos.com/hc/en-us/requests/new (please make sure to mention the link to the Forum thread in the message).
Alternatively, if the .zip file is small enough you can share it directly in the forum thread or via forum private message.

Thank you in advance!

Kind regards,
Iva
