At the moment there are 14 free and premium materials but I have already created over 50 materials that can be purchased from Unity asset store in one bundle : http://u3d.as/gq7
Any feedback and suggestion will be much appreciated. I will introduce very competitive subscription payment in the future and more free stuff as well as full projects.
Some finished examples:
- simple low poly cylinder with cobble material (4 textures - diffuse, occlusion, normal and height)
- Plane with window blocks material
- Plane with Destroyed concrete bunker material
