After Effects made my transparent background black, how do I make it transparent again?
I was making a graphic in after effects and I need my logo to be transparent. When I first put the logo in it was, but then I made it 3d and now it turned it black in the background. I tried turning on the transparency grip in the logo comp but it doesn't do anything. How do I make my background transparent again? I added a picture to show you what it is doing.
