Could you add something like camos/paint, like in Battlefield 4? You have a certain amount of colors, say tan, brown, some yellowish colors, and have multiple textures to apply them. Like Default is the default texture of the gun when you first spawn it. Splinter is a camo made up of small differently-colored, sharp-edged shapes. Flat is one color from the "pallette" of colors for the camo type. Spray looks like it's spray painted on with 2 different colors, etc. You could spawn in the camos from the Entities tab, and give it its own section called "Camos" or "Paint". When you choose one, you can then press C and open the menu (when the gun is held), and instead of using [1], [2] and [3], you can use the mouse to choose from the camos (and possibl the attachments for the gun), just because clicking [4] (or whatever number it would have been) would be tedious for cycling through (if you have multiple camos).

Here's a link to BF4's variety of camos and colors: http://cdn.bf4central.com/wp-content/uploads/2013/08/battlefield-4-camos-4.jpg
You have 3-4 colors, and then a ton of different textures to apply them to. I know this will probably not happen, ever, but I would like to see some kind of camo system. Thanks.
