Import using fbx
Mudbox supports the Autodesk® FBX® file format for data exchange between 3D applications.
FBX is a conversion technology that enables the acquisition and exchange of 3D models and related assets and media from a variety of sources more quickly and easily.
FBX supports a broader range of entities between Mudbox and other applications in many cases than the older OBJ file format. For a comparison of supported model file formats, see Model file formats.
FBX plug-ins are available for Autodesk® Maya® and Autodesk® 3ds Max® software, and is also supported by Autodesk® MotionBuilder®. Autodesk® Softimage® supports FBX through its Autodesk® Crosswalk plug-in features.
NoteTo import and export FBX files in other Autodesk 3D applications you must first install and then load the FBX plug-in appropriate to your application and version. To download the most current FBX plug-ins for your Autodesk application, see http://www.autodesk.com/fbx-downloads.
Open or import an FBX file
Select File > Open or File Import and set the Files of type to Autodesk Fbx, and select the file you want to import. For more import options, see Import a model.
For information on how entities appear in the 3D View after FBX import, refer to the table below.
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.
Grouping hierarchies — Model hierarchies that exist in a Maya or 3ds Max file are collapsed when the mesh is imported to Mudbox using FBX. Top level transformations and pivot points on the mesh are retained.
Mesh smoothing — Any edge smoothing (Maya) or smoothing group (3ds Max) information is not retained when the FBX file is imported to Mudbox.
UV texture coordinates
Only one UV set is supported for import by Mudbox; the first UV set.
Quick Select sets / Selection Sets
(Maya) Quick Select sets and Selection Sets appear in the Object List within Mudbox when the FBX file is imported to Mudbox.
(Max) Selection Sets appear in the Object List within Mudbox when the FBX file is imported to Mudbox.
(Mudbox) — After import to Mudbox, right-click the new camera that appears in the Object List and select Look Through. You can lock the imported cameras to prevent accidental dollying, tumbling, and so on.
(Maya) — FBX only exports the non-default cameras from Maya. The default persp, top, front, and side cameras are ignored. If you are exporting your Maya scene using FBX and want to retain the default camera related information when you import it to Mudbox, you must first select and duplicate the default Maya perspective (persp) camera (View > Select Camera, Edit > Duplicate), and then select the duplicated version prior to exporting your FBX file.
(Maya) — Maya cameras match better in Mudbox if the Fit Resolution Gate camera attribute is set to Vertical prior to exporting an FBX file from Maya.
(Mudbox) — Image planes are an attribute of cameras that get exported with the cameras when exporting an FBX file. After import to Mudbox, right-click the new cameras that appear in the Object List and select Look Through to view the image planes. You can lock the cameras associated with the image planes to prevent accidental misalignment.
