Unused Collisions
From Splatoon Wiki - SDL Foundation
I guess there's also unused collision for some models in this game...
Obj_GeneralBox (1.0.0)
By accident, the developers made a collision with the name "Obj_GeneralBox.kcl" which is every collision in the file combined.
Obj_GeneralBoxNoPaint
By accident, once again with a different model, the developers made a collision with the name "Obj_GeneralBoxNoPaint.kcl" which is every collision in the file combined.
