So I'm trying to make an animation of a drawing. I scanned the drawing and put into Photoshop, I also used the lasso tool to cut out the parts I wanted to animate and made it into a separate layer. Once I finished I imported the file into After Effects. When I did, it didn't give me an option to edit the layers and I couldn't make the "Composition - Retain Layer Size". I can't animate my drawing because I can't edit my layers. I need help. Thank You.
