ok now i'm literally fucked up the bo3 weapons just tried every scale and it didn't even fit to player viewhands :

here's an image if you didn't see it well.

Thanks in advance !

That doesn't look like anything to do with the scale of the gun, its just the anims are off.

It's not the scale, it's the bindings. Rebind the weapon to the weapon rig the anim is using.

Thx for all the replies . Me and tito are fixing it now .

+1. for ya
