I've looked around and I haven't quite seen this question asked so please don't kill me :)
I've created a simple stroke in AE and I'm compositing it with live footage. All I want to do is mask out parts of the stroke using another mask. I thought this would be simple by letting the stroke animate on mask 1 and then creating a second mask to cover up parts of the effect. However this isn't working. I think I'm missing something because it shouldn't be this hard.
