Video
<videoflash>OmnfM9fJiXk</videoflash>
VIDEO ON RUSSIAN LANG ONLY. (sorry, but I dont english so well to record video with it).
It's some kinda long, but should show almost of parts (rip (model, texture, sounds)/rig (how to avoid future errors a d etc)/export/setup (soundaliases, weaponfiles, how it's connecting themselves)) and include explanation (which you probably cant understand :< )
Hope you'll enjoy it or it can help you somehow.
