    Default Subtract a roto shape from another roto shape

    *EDIT* solved, it was Minus that I was looking for.

    How do I subtract a roto spline from another spline? For example, I have roto\'d a house with one spline, and I want to subtract the window with another spine.

    In AE I would just put the second mask on \"Subtract.\" Is it \"From\" or \"Minus\"? These don\'t seem to give me what I\'m looking for. Should I put them on separate nodes?



    Thanks!
    -Erik

    *edit* also, I have no idea where \'s are coming from : P

    I have the same problem. It is very easy in After Effects to mask off a bit of a key or other mask. but I can\'t get the same thing in Nuke. I also can\'t get the footage outside of a mask to dissapear.
    Did you solve one of these problems? Does anybody know how to do this??
