The new tool with proper bone lengths applied from skeleton. You only need to rotate a few bones to make it into "I" position. This is shown on video: https://youtu.be/6Gq0rtpjEY0
Some reason it doesn't work. I get an error no matter what files I use, even the ones in your tutorial. Some nonsense about "Unable to read beyond the end of the stream."
Can you tell me how to extract non-broken files? I can't find a way to do so...
EDIT: Never mind, I figured out how, but now my problem is the SMD files, which, since I use 3DSmax, aren't going to be much help unless they're converted. For some reason though, noesis cannot convert the animation files properly. Is there a way to get these into 3DSmax effectively? I've tried Wall Worm, but for whatever reason it won't import geometry for a rigged mesh.
