Well for the wunderwaffe, camo works for viewmodel, but not worldmodel. The PAP'd raygun viewmodel is now invisible for some reason.
EDIT: The PAP'd raygun isn't invisible anymore since I compiled my map. But it is now the same as the wunderwaffe. I made copies of the original ray gun and wunderwaffe xmodels and it still doesn't work. I made sure to check the weapon files's viewmodel and worldmodel. I even put the xmodels in the mod.csv and put the weapon files in my weapons/sp folder in my map folder. I also tried compiling my map, but the same issue persists.
