Hey guys, I know some other people have been having this problem and wonder if anyone's found a solution. It seems the pen tool is trying to "intelligently" decide whether I'd like to start a new mask, or add a vertex, and I'd rather it didn't. Given that my layer is very small, what happens is that it assumes that I ALWAYS want to add a vertex. This is a problem that's been a minor irritation before, but now is making my work nearly impossible.
is there any way to force AE not to switch to "add vertex"?
Nope, I would suggest using a composition zoom factor of 200 or 400%. It just takes a while to learn how to use the pen tool.
workaround: You could go into the previous mask properties and LOCK them.
Thanks, that'll help with half the problem. Of course when I want to draw a mask it's still a royal pain in the a**. It's not a bug, per-se but it's certainly not the way they intended it to work.
