Re: Can you make objects bounce off other objects in AE?

You can also bounce particles off from up to 2 surfaces using Trapcode Particular. Mentioning this in case you already have it. Newton sounds like a better choice in this instance, but I haven't used it. I believe there are also some very complicated ways to do this using the built in particle plugins, but involves lots messing around with displacement layers shaded to bounce from (see some of the Foam tutorials).
