Masking problems

Masking is an important part of the post production it allows backgrounds and overlapping animation to blocked out, they generally make the animation look more polished overall. The problem with the channel effects is they prohibit masking as they are already turning things to transparency. To get round this I needed to precomp all layers that required masking and make sure the effects where inside the precomp so they don't effect the mask. I'm glad this was a relatively quick fix.
