Reading the description, you typed "The Weapon dont have any animation because not have bones". I as far as I know, we are unable to extract weapon dummies from GTA 5. Also I assume that they have different names. Then for the first one, I believe GTA 5 has more dummies for weapons than GTA 4 does. I am unsure about the second one because it does not determine where the bullets shoot out from and ect.
I have tried two things in the Schematic Viewīoth ways have ended up with the same result. Whenever I shoot the weapon, the game crashes.
I am familiar with 3DS Max melee weapon modding, but modding the guns seems to have a problem.
