And experiment with apply modes of the projected video eg:hard light,overlay ect.If you can take a copy of the room video track make it grayscale and use it with a displacement filter as the pixel chooser track you might be able to get the appearance of wrapping the projected video around 3d objects. I think I’ve seen a tutorial for After Effects that does something similar with using a grayscale image to control the distortion of a displacement map- not 100% sure though.
