I want to be able to watch two Comp windows at once when I am animating. How tough is that to do?
I want to edit Comp #1's timeline. Comp #1 is nested in Comp #2. It is important to me to be able to see Comps #1 and #2 when I make changes.
There is some easy solution to this that I just can't see, right?
You can set up multiple Composition viewers in an edit-this-look-at-that (ETLAT) configuration. If you are viewing a composition in a hieararchy, lock the current Composition viewer, and then select another composition button upstream or downstream from it in either the Composition Navigator or Composition Mini-Flowchart.
