    Set Matte not working

    rmaytee Level 1

      I have a composition consisting of background aerial video footage, 3d rendered frames that overlay the video.  I have key framed a png of a tree that moves and scales with an existing tree.  I want to use the png tree as an object to subtract (erase) from the 3d rendered footage and expose the original tree that is in the aerial video.  I have added the set matte effect to the 3d rendered layer, and selected the png tree as the "take matte from layer" object, but it is not working.  I have tried every option in the effect, and nothing seems to be working.  Any suggestions?
