Hi there! for this project I wanted to model a customized weapon so I contacted a concept artist whose name is skipper lee and here is the result. At the end of the page you can see the reference concept I used. This gun can be used for short and long range because it has 2 shooting modes. The gun is divided into 4 UV maps. Contact me if you want to know more details!
