"Feel free to try it out -- a newer version with support for more
of 1.1 as soon as we have it. One thing that would be really useful is to
understand what people are using, and what they'd like to see added, so
please drop us a line and let us know"
The animation outputted seems to be only based on the animation curves.
If the maya scene contains constraints this kind of animation export will not work.
I think the 1.1 animation specification has too much overhead. Sure it is nice to have the ability to export hermite curves.
But for a painless game asset pipeline all you care about is sampling the animation, so it takes any constraints into account or other weird animation setup's into account.
So instead of making the artist bake his animations before export after complaining 3 times. It will just work and artists can use every single animation feature maya has.
