    Alpha, blending modes and compositions


      Hello, I am an animator and have a problem with blending modes in a composition. Hopefully someone can help me.


      I use After Effects CS5 on Mac OS.


      Please take a look at this screenshot:


      I have several layers in a composition (trees and shadows). The trees are set to normal and the shadows are set to multiply. Outside of this composition there are other elements on layers.

      The problem is that I get this edge between shadows and trees where the multiply does not apply. I need it to be applyed to the "outside" layer too.

      Trying to look my problem up on the internet I found out that the blending mode "alpha add" could solve my problem but I need multiply and alpha add, if that makes sense.


      Can I somehow get rid of this edge?
