I’ve been going crazy the last 2 days trying to figure out how to fix this.
I basically rotoscoped and tracked the mountain so that I could overlay it onto my CGI elements but for some odd reason, the edges show through even without any feather. I even tried just creating a mask for Ae and using that but it is even more pronounced. The only thing i noticed is that inside Mocha, the edges are set to 3 and even if I select the point and set 0 Edge width, it turns back to the default 3.
What is going on? I basically need the bottom edge of the mask to be invisible and the top one to feather a bit.
Here are all the screenshots:
