To test for transparency of my plane, I have a
background pic,
that my plane sits in front of. When I trace the picture,
the plane is
fully visible as a black square, with my figure pic in the
center. The
black areas are not clipped. It's as if the clip-map
effect HAS no
effect at all, since the picture renders identically
whether I have it
activated or not.
This process is such a snap in Imagine, I'm rather
surprised at
having so much trouble with it in this supposedly superior
program.
Again John and you others who responded, thanks,
for your
attention. I'm sure it's something obvious that I'm
failing to do.

To my understanding, it is always suggested to use a two
color, B&W image for clip mapping. It doesn't use
grayscale values as does diffusion mapping or transparency
mapping, with clipping mapping it's either "clipped" where
the image is white, or "not clipped" where the image is
black. Hope this helps.
Later,
