viscose, I'm not sure if this is what you're getting at, but if you have points projected on a surface you can still use the <Surface Closest Point> component.
This distance will be zero (approximately) and it will give you the surface UV coordinates. Does that help? taz On Nov 9, 5:50 am, visose <[EMAIL PROTECTED]> wrote: > In fact, driving geometry is much simpler than coloring a mesh.
