Unhandled exception when Render to Texture

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.

Here is the Vraylog text file as well.

Thanks in advance

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.
