What kind of file is a .hmp?
.hmp is the 3D GameStudio terrain or heightmap format. Its binary header identifies a generation such as HMP4, HMP5, or HMP7; the header records grid dimensions, vertex counts, scale information, skins, and frame data. Terrain vertices store height and normal information, and the loader builds a regular triangle grid from them.1
This is a terrain format, not a general-purpose image heightmap. Textures and the original GameStudio project may be needed to reproduce the intended appearance.
How do I open a .hmp file?
Use 3D GameStudio's MED editor or a viewer that specifically lists HMP terrain support. Keep any skin files and project references beside the terrain. For a portable result, export a copy to glTF or OBJ and check scale, normals, and texture coordinates after export.
Poly support for .hmp
Poly previews recognized HMP terrain and indexes its filename and available metadata. It provides an optimized terrain rendition to the agent. The visible terrain is available for visual interaction; individual height samples and every metadata count are not exposed as separate search results.
History and alternatives
HMP belongs to Conitec's 3D GameStudio toolchain. Later terrain workflows often use engine-native terrain assets or common heightmap images plus a mesh export. Keep the original HMP when you need to reopen it in MED, since conversion can omit GameStudio-specific scale and skin conventions.
