Can you use Portal lights with the Physical Sky? (thinking Mental Ray like) I've tried but haven't seen any improvement.
You use light portals with a skydome light, so if you plug physical sky into the skydome color that should work, just like using any other texture.
Hey Stephen, thanks for the answer.
That's what I´m doing, but so far it doesn't seem to work, with a Skydome/HDRi light portals work normally, but with the physical sky, they don't, I even get more noise.
why would this happen? Am I doing something wrong?
The noise might be coming from the 'enable sun' in the physical sky. You can try turning it off and adding a directional light.
Yes, I think it's the Enable Sun. That appears to give Arnold problems when it comes to sampling the skydome
