Hm... I've tried the exporter. ContentManager can't import it.
It just gives me this error: http://puu.sh/txVAK/bbdd6a7492.png
What's funny though is, this imports the model and the armature, but not the animations. The default Blender importer imports the animation, but neither of the other ones.
It's alright, really. I'd prefer to use Blender's default exporter if possible, and I don't really have a need for an importer at this time. I've already kind of planned my game around avoiding scaling bones, so this not working isn't the end of the world, but it would be a good thing to figure out for others.
