Lava Tubes 3D model

High poly sculpts I made in Sculptris of some lava tubes. All the tubes share the same textures, which are available in 2048x2048 jpegs, and include three color variations - Cold, Warm and Hot. The color options all have Diffuse, Normals and Specular maps. The Warm and Hot textures also have Emission maps. The zips contain the various models in the following three formats: obj, fbx and blend. Poly count varies from about 8000 to 40 000, depending on the model.
