Alpha Blend

Posted in: NUKE from The Foundry
Hey, I’m working on a shot where I need to do a roto on some trees. I managed to pull a decent key on the tree, but the edging wasn’t what I wanted to I had to go in and hand roto it. The problem I have is that I’m getting a hard edge when I’m blending the two. How can I get the edge of the roto to soften, but only where it is overlaying the other alpha?
