[HELP] Render to Texture with VRay errors

[-MerlyN-]

Hello all!

 

I am trying to bake some textures with 3ds Max 2012 and Vray 2.1. Unfortunately I get a few issues that so far I have been unable to resolve myself and found nothing on Google either.

 

So I hope someone here can point me in the right direction.

 

The first problem I face is, that Vray does only save blank files when rendering to texture. I have tried enabling and disabling the Rendered Frame Window and the VFB, but in all combinations only blank files are saved.

 

The second problem is that on some objects, I get the underlying triangle mesh as an overlay (see screenshot 1). When I render normally everything is fine (please dont be pricky about the lighting right now ). The material I use is a standard VRay Material with only a bump map.

 

This does only happen on some objects however, not all. In a desperate attempt to get rid of this I deleted the object and rebuilt it from scratch and first I was totally happy as the artifact was gone. Then I rendered the map again and the triangles were back.

Does anyone have any idea what might be causing this?

 

Any help is greatly appreciated as I am turning in circles right now and getting grey hair fast.

 

Thanks a lot!

I've found some workarounds.

 

The weird geometry shadowing vanished when I turned on "Store with irradiance map" in the Vray Light settings.

 

The VRay Complete Map was saved when I enabled "Apply Color Mapping" in the RTT settings.
