Anyone else have an issue with your mask not live updating when you make adjustments to it's shape? Of course, when I purge memory then it works but I'm not sure if I hit a hotkey that turned that off or what. I'm working in CC2015 but have experienced this in CC2014 as well.
Thanks in advance!
So, I have an update. Apparently in the current version of AE animating masks is impossible when you have other effects on a layer. So, you have to disable all of your effects then animate the mask. What the what??? Can someone at Adobe please explain this insanity? It also happens in CC2014.
I'm not experiencing the issues you're describing. There must be something different in your setup than mine. Your first issue sounds like you turned off the Live Preview functionality. Your second issue hasn't been described in enough detail for me to even guess at what the problem is.
