A various mix of textures (both hand-drawn and made in Substance Designer) created for use in Team Fortress 2. Otherwise known as "War Paints", these textures plaster existing in-game weapons to make them look unique. Usually submitted to Valve's Workshop for their approval.
Team Fortress 2 uses a single alpha channel for various in-game parameters like specularity, reflectivity, and illusion of depth! So in the texture showcases, I included both the diffuse and alpha, in that order.
