i playing around with some video mapping with AE. I build a 3D cube in AE which consists out of 3 compositions.
i try to figure out how i can "map" a picture or video onto this comps, which will be not distorted
when you look at the cube from the right angel, like this:
i would like to have the parts of the picture in my three comps, already pre distorted, so that i can see the undistorted picture fom a specific angle. Is this possible ?
You cannot bake projections in AE. Use a 3D program.
There's a funky way around this demonstrated in a tutorial I did a long time ago for AE 5.5 (not CS5.5). You can find the tutorial here. What you are describing is in the section called fake 3D. Making it work in your case is a matter of blend modes and shadow catchers.
