Rune's illusion.inc is *very* useful! I wonder if he knew how it would 
be used when he made it? I too tried to map an image to the viewing 
area, but failed miserably. Thank goodness he figured it out for us ;) 
He should get some sort of award for that file!

The camera pigment takes render options from the whole scene file. I 
suppose you could place a copy of the mesh in an ambient cube with 
radiosity applied, but you would have to use radiosity for the final 
image. But with MegaPOV, can't you turn radiosity off for certain 
objects? If so, you can probably do it without having to use radiosity 
for the final output.

I recommend that you don't give up on learning Blender. While looking at 
tutorials, keep your eye on the keyboard shortcuts, as they make the 
program much easier to use.

But you can't use the proximity macro for mesh objects :( If POV 
supported calling inside() for mesh objects, it would work. I wish 
somebody would figure out a way to get inside() working with meshes!
