ICE - create weightmap on intersection

[Rob Wuijster]

I'm pretty sure I've seen an ICE setup that did the above, but cannot 
seem to find it....

Think of sphere intersecting a plane, and on the outline of the sphere 
the weightmap is created for the plane. I want to use the WM to drive a 
RT setup.

cheers for any tips/links.
