Thanks Skyth! I can finally export the skeleton. I was worried I had to do the rigging myself as I'm horrible at doing rigging, weight paint is a pain for me. I can finally work with these models. I also found that Buddy (Avatar) has some weird mouths that seem to be the same, if I remember they were "rb_mouth" and "mnq_mouth", also it was weird for me since the only species you can pick that I remember are wolf, cat, bear, dog, bird and hedgehog. Are those some "test models" or dumped ideas from SEGA? They look like hedgehog mouths, they might be from that, but I didn't really play with the hedgehog avatar, to be honest.
