instance models and animation clips 2005-02-21 - By Alan Jones

hmmmmm - interesting idea. Though I'm not sure how much benefit you'd
get. Would need some more thinking. Though you could speed up
performance in XSI by using a geoshader in combination with a .mi file
sequence. Might give some pluses on the mr side too seeing they'd only
be loaded in when the bounding box was hit.
Cheers,
Alan.
