True. Without access to the original 3D project, does anyone know of a sneaky way to do something similar without any UV data? Only the original rendered video?
It may only be possible to do it manually. Either way, thanks for the responses everyone.
Did you buy the project? http://videohive.net/item/transforming-cube/2618153?ref=donvaldone
If you have a pre-rendered 3D object then you can try plainer tracking in Mocha and using corner pinning to add a texture to the surface. Without seeing the project timeline I can't give you a better idea than that.
Not yet and I've tried to contact the author multiple times. I assume just the AE source, but I could buy it and request a refund if the C4D files aren't included.
I will look into plainer tracking. Also, I could always just study the motion of the original animation and recreate it myself in Cinema 4D -- just wanted to avoid the hassle if I could spend a few bucks on videohive.
