Hornet and I tried to look into these objects with upspring but results were inconclusive. For Hornet the rocks show different textures when loaded subsequently. For me they show nothing at all until filled by my selections.

objects3d/rocks30/rocks30_map_XX.s3o was designed so that a mapper could place their texture in the map file and then use the rocks. They dont work without the mapper supplying the needed textures.
