So I found a tutorial on how to fix the crotch gun for CSS skins w_ models. It works fine in hands but its slightly fucked up.
Problem #1. The w_ models goes invisible when I’m away from the camera (see pics).
Pic1, near the camera
Pic2, away from the camera
Problem #2. Same as problem #1 but now, with the w_ model spawned on the ground.
Problem #3. The physbox is very fucked up (se pic).
