(www.mediafire.com/view/lgrrwtmump1dwz3/EXAMPLE.jpg) - EXAMPLE / DESERT EAGLE MOD REPLACER FIXED
So lets say you download weapon mod replacer and you find out, after NPC or Player dies/drop weapon, there is only magazine floating in air, instead of a pickable weapon and mod author not respond/dont care/dont know etc. how to fix it. Or maybe you are mod author and wanna fix it
Well i have fix - tutorial for that (actually tested on 8+ different weapon mods and worked flawlessly).
Some models that i fixed this way and i really like (check comments)
Reason is that modded weapon missing .bound file, which somehow gives weapon "ragdoll/collision", so we just need add .bound file from vanilla and add reference to this file also.
Anyway here is my folder with tutorial (screenshots 1-11.. if you actually download screenshots there is better quality. Mediafire gives shiat preview) .Im using Total Commander here, but i hope its understandable even with that. I will not make tutorial how to work with OpenIV and its basics

If you cant export .ydr to .odr (openformat), because "model protected", you need to contact mod author i guess, so he can fix it himself..
