I must confess… I was never a big fan of shape layers… we just didn’t get along. I was used to using masks but suddenly (around AE CS3) the same mask tool began creating Red vector shapes.
At first, they seemed cool enough but after accidentally adding shape layers to my comps, instead of masks, I lashed out! I even made a few jokes at the expense of them. It was wrong and I apologize
Since working on a few space movies, I really took the time to learn the tools better and began to realize how cool and powerful they are.
There are some extremely cool things that can be done with layering and ways to randomize path position with a wiggle settings and other cool things that would be impossible to do with masks.
I’m nearly finished with with an unrelated tutorial (See below) but I’m looking forward to incorporating some interesting tips about shape layer creation!
