However, I must point out that we were very impressed with the rendering
part once everything is working. Behavior outputs a file with all the
bone rotations for the characters. This file is then read by a geometry
shader that recreates the envelope operator from XSI. mental ray can
then render thousands of characters in seconds (yes... that can be under
a minute).
The fact that you need a mr standalone license for it and it doesn't
come with Behavior is somewhat surprising, to stay polite.

Francois is absolutely right on both these points.
In fact, the scripting of the crowd motion was for me not that hard. The
really tough bit, though, was getting a reasonable pipeline for the
process
you go through for putting together the XSI and the Behaviour bit and the
rendering thereof. The way it's handled now is kludgy to the point of
being
almost pointless. If you find yourself going through a dev loop, which you
will do, either creative or technical you'll find this a major problem it
being both slow and error-prone. If you're working with a client think of
good explanations when he asks you why he has to wait a day or more to see
small changes and why sometimes there's nothing for him to see because it
broke. A simple 'it's the software's fault' doesn't work; you, after all,
chose to use it. :-)
