  Slicing a spherical imagemap (Message 1 to 3 of 3)

I have an image of a sphere I'm trying to render, but the outer surface 
of the sphere is an image map (tiff), and the scene calls to cut the 
sphere to show a cutaway. Now, I'd like the cut edge to show the same 
color as the surface of the sphere along the same radius as the point 
(just like rendering a sphere of a smaller diameter with the same 
texture map). But when I difference{} the sphere with a box, the cut 
edge is opaque black (which looks really odd, since the sphere has a 
slight transmit/filter texture). Is there a way to get the image map to 
be not just a 'skin' on the surface of the sphere when cut, but to 
penetrate down into it?

Put the pigment (or texture) with the image_map into the difference 
statement instead of only the sphere and it will appear all the way to 
center.

Ooo, thanks; that worked!
