I've been trying to figure out a way to do the following, and short of painting in the frames by hand, I've been coming up empty.
What I want to do is similar to this: Say you have an image of a landscape, with some pronounced hills. I want to fly an object into the scene and have it cast realistic shadows. Ok, no problem...front projection mapping, throw some shadow-catching geometry in...that much works fine. However...here comes the catch that's got me puzzled: Say I need to have one of those hills deform....like maybe a giant boulder comes flying along and makes a huge dent in the side of one of them. I can't seem to figure out how to get the texture to stick on the deformed geometry. Sticky front projection only stays sticky if you move the camera...if you move or deform the object at all, the texture just slides right through it (or rather the object slides through the texture). I thought maybe surface baker would work, but no luck there...it just output a black frame.
Anyone have any ideas how I could make something like this work?
