Experimenting with front projection roto to make a ghost. I am not sure why the sky came out white, this is default chor. It looks kind of cool tho.
definitely looks cool - neat idea. Poor thom.
the sky/background is white because I am assuming your roto is white (the .mov was not included with project) - rotoscopes in the chor are used to fill up any areas that aren't filled by any of the models, in this case the sky. The roto is also used for the image of which to project onto models which have the front projection option ON.
If you want the background image to be different from the front projection image - you might try having fog ON with a fog image (with the image different than the camera rotoscope). Have the start end distances for fog be farther away than the front projected models.
Then you can have a different image to use for front projection as well as for background.
Not quite sure why you had to front project Tom (why not make it a whitish/transparentish model?) - love the glow effect around him
For something even more strange try making tom ghost also flat shaded as well as front projected - with white roto - you might get a melty look - depending on the lighting.
