What do I need to do, to link mesh with a skeleton properly?
In editor I'm setting helmet in particular place (like in a screen), the mesh is automaticaly linked with skeleton (I suppose so) and then I draw it with:
It is drawn in a proper height, but it doesn't rotate in x axis.
Should I link it with specific bone? How to do it?

after linking with skeleton you need to set per-vertex skinning

Ok, sorry for lame question, but I have no idea, where to do it - didn't have to bother about models till now ;-) How should I set per-vertex skinning?

Neither can't find it in editor nor code...

there is video tutorial in model editor main website page (tab key, or through menu skeleton option)
