The Adobe After Effects CC feature
Composition -> Save Frame As -> Photoshop Layers does exactly what I want. However, it is very time consuming to do this for each frame (I am animating a game character in Adobe After Effects, and then using the
.psd files to create a sprite sheet).
Is there any way (perhaps a script) that can repeat this action for each frame, automatically numbering them, so it's one-click to export the entire sequence?
