Maya Particles.. My thoughts. 2005-05-06 - By Vince Fortin

Ouch really?
By the way Aloys (and others), sorry for the basic question but how do
you guys work with compiled ops ? I mean, does the operator runs
through indexes or does it allow access to per-particle data like Ids?
Can you provide examples of custom ops you have developed?
I've always been under the impression that parsing cloud vertexes is a
bad workflow because of the indexes being re-injected into the
simulation making them kind of hard to track...
Personally pEvents fill my needs, maybe somebody needs to open my eyes =p
