These are some of the Environment Textures I created for Rage 2.
As the only Texture Artist on the project, I was in charge of our Designer library, feedback and support for outsourcing and the rest of the environment team as well as the production of most of our materials.
All materials, except the first one where I used Zbrush to create the main veins, was created using Designer.
Most of them where created to be blended with other materials to break them up.
