In 2012 I had modeled this Barret M95 at the insistence of my son who was in love with this rifle playing Battlefiel. At the time I did not know a lot of nodes, remember I posted this work in a forum of blender but the textures were obviously negative comments on the lack of dirt. It 'the first time I use multiple uv and multiple textures, I tried to keep the light scratches in the metal and dark in the plastic. I'm not happy with the result in the plastic but the texture that I found were very dirty, hard to find a texture 4 with scratches. However I think it is better than the previous result.
