So in Version 2 of Fixed Kanopy Killer Scattergun it includes 70 FOV Fixed Arms, improved smoothing, less clipping, a fixed world model, and new animations. I figured that I would completely redo it in 3ds max since blender broke the smoothing, I also fixed the reload animations to clip less with the gun. The world model problem was known for a while but I was waiting on the Scattergun to go cmodel but I don't think it will anytime soon.
Now that the scattergun is a c_model i've updated the mod but the clipping can't be helped much anymore. I've done my best to reduce most of the clipping but there's only so much I can do without replacing animations.
