No ICE huh...... I know! I know! Go to the grocery store. Buy a pack of lunch meat, the smelliest cheese you can find, and some monkey bread. Return to work and make your lunch from the ingredients. Whilst everyone is running away from the smell of the cheese, cheat and use ICE.
I know, I broke the spirit of the challenge. Guilty as charged. But I bet Ed liked the solution. :) -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) Mymic Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party. -----Original Message----- From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Matt Lind Sent: Tuesday, February 11, 2014 2:54 PM To: softimage@listproc.autodesk.com Subject: RE: Survey - how would you do this? Softimage doesn't have a particle system anymore. ICE replaced it. To answer your question - yes.

With those restrictions, get a super fast animator to animate them by hand. Eric T.
