I have a video of a person that has fallen into a liquid shot from above. I'd like to have a ripple bump map to give the impression of said liquid being displaced. I thought 'wave world will do the trick'. However, it seems to only look at one frame of a precomp. When I move the layer along the timeline it gives me the result I want, which is a rippley bump map reacting the to movements of the actor. Am I missing something?
IS there away to get it to recgonise a full comp? Is there a way to animate a layer in the timeline?
