This aims to improve the detail of the body textures (in comparison to the cyberfaces), gear and the suits. To improve the body textures, I've adjusted the intensity of the arm/leg normal maps, and added a subtle skin overlay to each of their normal and AO maps.
Update V4: Added more detail to leg textures; toned down muscle effect on ripped leg texture variants. Accessories that were showing up gray when set to white color should now be much more white. Improved suit design, shading and specular textures. Pants now match suit jackets much more closely.
