# Error: [driver_exr] defaultArnoldDriver@cameraMapperOutput: can't create file

I'm trying to Render Selection To Texture and keep getting this error even after full restart. It was working just fine a minute ago.

# Error: [driver_exr] defaultArnoldDriver@cameraMapperOutput: can't create file "C:/file.exr": OpenEXR exception: Invalid argument.

I figured it out. The object shared a name with another object in the same scene but were in different groups. When I delete or rename either objects it renders perfectly. This is a bug, which extends to the newest version of MTOA as well.
