Model file formats

Mudbox currently supports the following file formats for storing and transferring model data.

File extension | File type | Entities supported/Uses
--- | --- | ---
.mud | Native Mudbox file format | All entities created in Mudbox are stored using this format with the exception of the bitmap files associated with paint layers which are stored separately in a -files directory using the file formats specified when you create a paint layer. For a list of supported image formats, see Paint file formats. Use this format when storing your normal Mudbox projects.
.fbx | Autodesk FBX | FBX supports a subset of entities created in Mudbox. Use this file format when you need to transfer models, UVs, simple shading information, sculpt layers, and paint layers between 3D applications that support FBX (Autodesk Maya, 3ds Max, Softimage, and so on) For a list of Mudbox entities currently supported by FBX, see Export using FBX.
.obj | Open geometry format | OBJ is a simple file format that represents 3D geometry only (no paint layers, shading materials, or lights) — the faces that make each polygon, the position of each vertex on a face, the UV texture coordinate associated with a vertex, and the normal at each vertex. Use this file format to import and export models and UV texture coordinates (and models into existing sculpt layers) when transferring between 3D applications that do not support FBX. OBJ also supports selection sets.
