I want to make the edges rough, roughly similar to hair. This doesn't need to be particularly accurate, as the image will be displayed behind some cloth (Giving the impression of a shadow passing behind the cloth). The Roughen Edge effects would be fine if the layers where not animated, but the shimmering the effect causes doesn't look as good as I would like. I've tried using the CC Hair effect, but to no avail. Anyone have any ideas?
(The rig consisted of a skeleton rigged with DuIK, with Puppet Pined shape layers acting as musculature. I plan on using this "hair-effect" on each of the relevant muscle layers to create the idea of short hair.)
I just talked with a friend of mine, and he recommended I switch the order of effects to have the Roughen Edge" before the puppet pin. That works pretty well for most of it. He also pointed me to this: http://aescripts.com/smart-precomposer/ to precompose the shape layers.
