I have tried everything, but nothing is handling the noise in the shadows.
I applied a material override so it isn’t materials. The back of the car looks fine and some of the geometry like the garage door is good. HELP!
It looks like double faces or duplicated geometry.
Double faces
Yep, that was it. I have no clue how that happened. The file was fine two days ago and I didn’t do anything to geometry. Oh’ well… at least it is fixed. Isn’t there a script running around that cleans up double geometry?
MoonDoggie’s script helps in some cases:

Or you can try to increase the secondary ray bias to something like 0.1.

Yeah it does help some of the time (if the objects are exactly identical), not just if two faces are overlapping. Good luck, it’s possible with a script to go through every object/every face, but frankly it’s too time consuming and the end-user wouldn’t wait for the execution time. :), to I usually just put a material override with a vraydirt in the diffuse slot, and self-illum to 100%, this reveals double faces quite well.
Good luck,
Colin
