What I want to do is to emit particles so that they stick to the surface of an object. The problem is, this object has displacement, so the geometry that is used as an obstacle to my particles is not the same as the geometry that is rendered. So I was wondering if somebody knew how to obtain actual editable geometry from a displacement map in XSI, or know of another way to do what I want to do. (The best idea I had was to use the object as an emitter, and the siplacement map as a texturemap that drives the speed of my particles, and then have the particle move for a second, say, and then stop. This might work, but it'd be a lot of messing around, so I'm hoping somebody might have a simpler solution)
Thank you!
