I have to animate a vacuum that travels over a carpet. As it travels over the carpet, it must reveal the layer beneath it - almost as if it is wiping it away or erasing it as it travels along the path. How do I do this? I have tried masking each "pass," but it is not working. I am new AE and have no idea how to accomplish this at all.
Does anyone have any suggestions? Is there a tutorial that may help?
