Matte from Geo intersection
Can anyone offer a suggestion how to achieve this? Just a simple matte on an object where another one is intersecting, so the surface inside the volume is white, outside is black. The volume itself would be hidden. The geo isn't very dense, someone here suggested generating a wieghtmap via ICE, but it won't have enough resolution.

There is a handy booltrace shader by Alan Jones on http://rray.de/xsi/ That maybe sounds similar to what you are looking for Jeff From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Eric Lampi Sent: Thursday, January 23, 2014 10:55 AM To: softimage@listproc.autodesk.com Subject: Matte from Geo intersection Can anyone offer a suggestion how to achieve this?

Re: Matte from Geo intersection
on the material you want to have generate the matte, use a rayswitch to make refraction and transparency rays white, all others black (or a different color for each, whatever you need). Then make the other object 100% transparent with a refractive index of 1, and turn off its shadow-casting abilities.

Ahh thanks Ed, that's exactly what I was looking for.
