Maybe it’s easier to just explain what I’m trying to do. I want a movie (texture) to be projected thru a thin transparent rectangular box (not just a plane, it needs to have depth). The box is transparent and has the movie texture applied to it. I want to shine a spotlight thru it so fog or volumetric light would give the beautiful “stained glass window” effect on the fog and the ground, just with a movie instead of a still.
This is what I have so far. It’s not right, but gives the idea. The fog is just barely starting to show the movie on it, but I think that’s from the environment, rather than the volumetric light.
I’m wondering if I even need a frame, or if the alpha channel from the movie could act as the “lead” areas. And I suspect it may get tricky projecting thru both sides of a transparent object, rather than just a plane. Any thoughts are appreciated.
Thanks,
Jim
