bigworld engine model (.visual .primitives)

[a723119159]

I've been working on this for a while.
I found netease games based on bigworld engine.
Now,I can get mesh easy.
But,I don't have anyways to export bone (.visual)
I can use uu3d but it need 56$.And I use Blender plugin to import it, have many mistake.
Any other ways to export bone?
Thanks!
