You're welcome. It's mentioned in the tutorial for creating splines, (or, at least it was in the C2 version.) but they do seem to have a problem with leaving some important points out of the refernce locations in the manual. :< I've been fighting with the particles for the last couple weeks! And the manual is NO help. When shading, there is the 'particle shader.' Is there ANYTHING in the manual about how to use this little gem? Huh? HUH? No. BUT, was there a listing on R'Osity about it a year or so ago? YES! Gotta love it when the customers help each other out more then the company that MAKES the stuff!
