I highly suggest you write a mini tutorial.
Took me a few minutes to figure that out when I first tried it.
Good idea, later I'll write up a short walkthrough with screenshots.
I figured it out right way. However, there are a few oddities I noticed where the animations make the model twist itself oddly at times. That's due to the interpolation, though.
I have noticed this. It seems to make everyone move like Voldo, which is decidedly a bug and not a feature. I'll have to experiment later, with getting the interpolation to behave. Perhaps I could add an option to insert more keyframes for more better interpolation, or figure out how to animate on Location, Rotation, and Scale rather than matricies.
(I've never used COLLADA-anything before this weekend. That spec is pretty
obtuse.)
