Why is my alpha layer showing so much noise in the shadow catcher? When I want to composite this into Photoshop, I see the noise very faintly.
Could this be indirect shadows? As far as I know, shadow catchers now take them into account. You may need to either change some sections of the catcher to holdout instead, or maybe denoise the shadow pass.
So turns out it was that I had the shadow catcher render layer samples set really low.
