CoD4 Camouflages

CoD4 has a wonderful asset manager, it's very easy to use indeed, but i'm trying to, right now, get camos looking nice on here, MW3 has the camouflage map Classic

looks nice and bright yes?
this is the best I can get it looking in CoD4:

I tried this with multiple other camouflage maps and it yielded the same result, my setting in asset manager is this, cosine, specular, normal, detail & col all set as they should

The K7 gun itself looks absolutely fine in game, i.e like CoD Ghosts, just, and this is for a lot of custom guns, when I try to apply a camo from one of those games, it's very dark/shadowy in game..

Is there a specific setting I should be doing in asset manager that i'm missing?
