RocksHD features 35 rock models including different geological types like sandstone, greystone, edged rocks, large formations and even dark lava rocks. It's aimed mainly at game-developers but also useable for all other people in the 3D field of course.
Each rock has been hand-crafted in Zbrush with also painted 2048px textures made from then high-poly bake including normals, AO and Cavity. The textures are seamless which means you can rotate each rock in any angle without looking at nasty edges or texture seams giving you all artistic freedom your project deserves.
Like usual lots of common model formats are supported: .max (2010), .fbx (2009), .obj, .3ds, .dae (OpenCollada) and .gmf (Leadwerks)
Also textures included in the .fbx for easy drag&drop functionality plus .dds 2048px normal,diffuse and specular setup.
