You can export your work from Mudbox and quickly import it into Maya, 3ds Max or Softimage using File > Send to [Autodesk product]. Send to exports from Mudbox using the Autodesk® FBX® file format. See also Export using FBX.
The Send to options are designed support a common, iterative, round-tripping workflow that lets a production start with a scene in a content creation application (Maya, 3ds Max, or Softimage), export the content to Mudbox for added paint or sculpting detail, then merge back to the original scene.
In this workflow, you can continually refine content in Mudbox as needed. In particular, you can incorporate topology changes midstream in the sculpting or painting process, updating the active object in Mudbox when topology is modified in the content creation application (for example, to provide greater resolution in one specific area, or to support better deformation by the rig). See also Import topology changes.
To export to Maya, 3ds Max, or Softimage
Sends only selected objects to the other application. (If nothing is selected, Mudbox sends the entire scene.)
Adds or updates paint or sculpt layers to an object in the other application.
Updates only the textures of an object in the other application.
Adds a selected object to an existing scene in the other application.
Depending on which option you select, Mudbox launches your other Autodesk product and imports the file. If your other product is already running, a prompt asks whether to save your scene before importing the Mudbox file. If your other product does not launch, see Troubleshoot file import and export.
