oh, I didn't notice the replies. you *need* a shader for anim9 to work.

I also just stumbled upon coa_tools and it looks nice, even if I barely understand how it works. I think the main thing we are missing is not an importer but something that lets you work sensibly with this stuff once it is imported. Guess that would correspond to the "runtime".

I noticed that "Move or Die" did something similar, so maybe it's out there already.
