yeah i saw that but, i didnt make the original models i just edited them so they could be used in obsidian, so lol
also you may notice some times the custom models hold there guns in funny places now this i find doesnt have much to do with the model but rather the map :\
afterall in model viewer they are all held correctly lol iot is indeed a head scratcher =P but this was an old thing that was noticed awhile ago on the first player model pack

so yep...
and by all means if you want to fix the shine hehe go ahead ^_^ i wont mind
