Hello,
I need your help, because I get weird issue when rendering with path tracer 
The textures will not display correctly, as you can see on a brick wall (or any other type of texture)
and the result with Path tracer
It’s all back in order, I’ve broken down the groups of my model in sketchup and I’ve chosen to export it from sketchup in FBX, and reimport it in TM, which solves the problems most of the time.
Have you tried using DOF in camera, this worked for me…
