Testing out vray.
Stumbled upon one nasty problem that turned the right part of the sofa black or white. I asked around some forums but they never came across that thing.
Posted the scene file and they couldn’t find out what was the problem.
It worked with standard rendering and in the viewport (and sometimes in the vrayrender with some fixing.. note only for a while and then it turned bad again)
Really odd
I finally found out by myself that the axis/normals somehow messed with the mesh and with vray
(don’t ask me what has happened)
but I could reset the systems axis in Cinema 4D and that worked.
* This was a bug and is fixed in newer versions of Vray
