This post is only showcasing materials work (Textures, Smart Materials, Grunges Maps, Stencils...).
The weapon wasn't modelled by me. It's the job of my good friend Javi. Please check his work here:

Materials showcased here: Wood. Layering of different library woods and different weapon metals, plastics, fine detailing plastics, grips, and many more. Smart materials also developed and materials tested in their blending interactions, with masks created and added to the library for this purpose.
