Hi, I have been trying to “render to texture” and keep getting this error. Can someone point me in the right direction? Thanks a lot.

Something may be wrong in your setup.  
Have you tried resetting the render settings?  
Does it render fine if you do not render a region?

Could it be that you used max default maps instead of the Vray ones. Like “Complete Map” instead of “VrayCompleteMap”. This usually causes unhandled exceptions when baking textures.

I do this mistake almost every time I need to bake textures (1-2 times per year ) it would be great if Vray can hide these incompatible maps .

Wanted to say thanks a lot for the advice. I didn’t have time to troubleshoot more but will get back to it.
