Mudbox does not support file, attribute, or directory paths that use double-byte characters in the names (such as found in Japanese, Korean, Chinese languages). Text strings should be restricted to single byte characters only (Latin alphabet). Using text strings that contain double-byte (extended ASCII) characters may result in an error or data loss.
The .obj format supports polygon mesh data and can be useful for importing and exporting polygon models to and from other 3D applications.
The .mud format is the Mudbox proprietary file format. Unlike an .obj format file, it can contain multiple subdivision levels, sculpt and paint layers, lights, materials, cameras, and reference painted textures.
The .fbx format can be used between 3D applications that support this file format. A subset of the Mudbox entities is supported. It can be useful for importing and exporting data between 3D applications such as Autodesk® Maya® and 3ds Max® . For more information, see Export using FBX.
