Rendering Objects with wrong facenormals

V-Ray V-Ray for Maya Issues
1

Hey…
happy new year to everyone… :slight_smile:
I have a problem, because I use a lot of imported CAD-data where sometimes the normals of the polys show in the wrong direction. When I render it in maya or mentalray they worked fine, but with vray they are totally black. Now when I reverse them they also don’t look right (sometimes they do, sometimes not). Is there a button in the materials or renderglobals that ignors the normals?

Thanks a lot,
Michael

I dunno where the button is in maya, in max it’s in the VRaymaterial as “reflect on backside” and “2-sided”.

Mind you you will still face issues with passes that rely on normals, like AO, Normalpasses etc.

There is a known issue currently, which should be fixed for the next official build.

Great, thanks. Can’t wait for the next build, will GPU-rendering be included…? :wink:

It will not go into V-Ray for Maya just yet.
