that's what I suspected, but the lack of psk SkeletalMesh is exactly the issue I am concerned with. Still in this other post
http://www.gildor.org/smf/index.php/topic,87.0.html I read (without understanding it completely) that md5anim could contain hierarchy information. Isn't then possible to extract the base frame as skeleton hierarchy? I suppose that even if the resulting skeleton wouldn't be in the reference pose, the subsequent animation import could animate it correctly. Do you think is a viable solution?
Sorry about the wrong forum section...
