How to setup pbr rendering?

How do I setup pbr? I can’t seem to find anything in the 1.9 docs. Any help is much appreciated.

Are you looking for this?

I’m getting an error when I run my script. It says that my Temp folder is not found though I set the path correctly. Anyone know what I’m doing wrong?

I haven’t experience with that kind of case because I’m newbie in this field
