Shrinking Bits in MdlVis

[GhostThruster]

I am trying to animate a model in MdlVis, and I've assigned all the bones to it already. But when I rotate a bone, the vertices attached to the parent bone and all children bones shrinks. What am I doing wrong?

Nevermind, I found out the problem was that all the vertices were attached to bone_root.
