Would like to ask what about bone scaling, espacially for customizing characters using to change size of bones in local directions...

I think you all know what i mean ^^ Can't find anything in the documentation to this

Greets

PS: is it this in EE::SkelBone ? OrientP & operator*= (const Vec &v)

You can manually adjust scale and other parameters while animating bones, using CSkelBone::members
