Making my way through some decently complicated masks/rotos.
I've hit a snag where Ae simply stops working after trying to view the masks in Ae after pasting them on to a layer (not using Ae masks, but rather pasting directly on to a layer to get the soft edges). CPU is at 100%, and the preview monitor is simply frozen.
I can scrub, open new panels, move things around, but the preview is locking up Ae something awful.
I tried deleting memory/image cache.
I can't quit Ae, unless I force quit. If I force quit and open back up, I can work for a few frames until something locks up the display.
I tried reducing the project to just the precomp, nothing helps.
