MDLVis : Yellow bones & Missing arms

[Koward]

[SOLVED]
Hi !

Let me explain the initial situation : I'm writing a little tool in Java and I want to import WoW models to mdx as proofs of concept and to learn a couple of things. Everything works pretty well.

I used MDLVis today with one of my models (human male) and I noticed arms were missing during animations. Funny.
Obviously I searched what mechanic in MDX could hide whole bones&meshes during animations.
When I view the bones (not in the "Anims" tab, in the "Bones" tab), and when I click on one, other bones around it become yellow. What does that mean ?

That fits perfectly to my missing arms.
So I'm looking for somethink like the GEOA chunk but for bones, or more "main" bones.
If you want the MDX (pretty heavy, 24 mb) : https://www.mediafire.com/?8d3i6e6f9c7n5hu

Any idea ?

Solved : it was a problem in the bones.
I added new "useless" values in Scale as vectors (0, 0, 0).
But that's wrong. It works for translation (because doing nothing in a translation equals to a (0,0,0) movement), but for scaling the default value is (1, 1, 1) (since scale is a multiplier).
