You
            can add one or more models to your current scene or layer using
            the Import and Import
               as Layer features. Importing a scene loads an existing scene
            from disk and adds it to the contents of the current scene.
         
         Import as Layer loads
            a saved model into the scene and stores it as a layer on the active
            object. For more information on supported model file formats, see 
                     Model file formats.
         
         Import as layer makes
            the following workflows possible:
         
         
            - Allows multiple sculptors to work on
               separate versions of the same model then combine their work by importing
               the separate models into one scene as separate layers.
            
- Blend between different design iterations.
               For example, you can import two different versions of the same model
               as layers and then mask out areas on each to produce a result that
               is a hybrid of the two original models.
            
- For facial animation purposes, import
               variations of the same model for facial targets. You can then use
               the opacity sliders for each layer to blend between the various
               facial targets.
            
- Update the pose or proportions of a model
               when changes have occurred in the original 3D modeling application
               or by another sculptor in Mudbox.
            
- Update a model in the original 3D modeling
               application, load it into Mudbox, then import your high resolution
               version of the model as a layer to update the new version with your
               sculpted detail.
            
NoteMudbox 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.
            
         Import an existing scene
               into the current scene
            
            
               - From the main menu, select File
                     > Import. In the browser window that appears, navigate
                  to and select the file you want to import.
                  The model loads in the 3D
                        View.
                   NoteTo sculpt on the
                        mesh, ensure it is first selected in the Object View.
                      
Import an existing model
               into a layer
            
            
               - From the main menu, select File
                     > Import As Layer.
               
-  In the file browser window that appears,
                  select the file(s) you want to import, then click OK.
                  Two import options are
                     possible:
                   
                     -  Vertex IDs -
                        Use this setting when the imported model is topologically identical
                        to the active object.
                     
- UV Position -
                        Use this setting when there have been updates to the imported mesh
                        that have changed the model’s topology or any situation that would
                        otherwise not allow for a Vertex ID correspondence.
                     
 NoteYou can select multiple
                        files for import when using the Import As Layer feature.
                        Each file is assigned to a separate layer.
                      
The scene is imported
                     into a new layer on the active object. The new layer is automatically
                     selected for sculpting.
