The models and Base textures for this set are free. You can find them by searching through my models.
A set of seven sculpted rocks. The rocks all share the same 2k texture and have two 1k ground textures. The textures are in .png format for the rocks and .jpeg for the floor and include Diffuse, Specular, Normal, Emission, and Height.
I made the rocks in Sculptris and used Blender to export them to other formats. Previews were rendered in Anim8or using a Raytracer.
