So, let's say I create a bezier mask and animate the control points to make it grow or change shape etc. I've noticed that when I go into the keyframe editor and move the keys I've created, nothing changes. I can move the endpoint closer to the start to speed up or vice versa, and the timing stays the same. I can't figure out what I'm missing or if it's a bug. The only key parameter on the mask layer that it says I'm animating is "shape animation", so that's the one I tweak, but nothing moves.
