my C++ is as clear as muddy water. Although I plan on changing that
sooner than later.
I should have thought it would have been something as simple as what you
said. Which sounds like what Kim was explaining as well. Just that most
of my scripts I use OM scripting, so I don't access the hairs in that
fashion unfortunately. but thats a whole other gripe of mine regarding
hair geometry in Soft. Ah well, thanks everyone for the quick replies.
I'll give everything a looksie!
