You can select objects
            to include in your output by using the Object List or the Edit Output
            mode. Objects that are part of an output are displayed in the Object
            List. For each selected object, you can decide if you want it to
            be visible in the final render or not. Non-renderable objects, such
            as lights and cameras, are always included in outputs.
         
         TipWhen you create a
               new output in the Outputs list, it is empty by default. Enable All
               Objects in the Objects list to display all objects in the scene.
            
         To select an object:
         
         
            - In the Object List, click an object.
               Selected objects are
                  highlighted in the Object List, schematic, and image window. 
                
- To select additional objects, Ctrl-click another object.
               NoteWhen you select multiple
                     objects with different visibility settings (Visible or Occluded),
                     the visibility is indicated as Mixed.
                   
To output all objects:
         
         
            - In the Object List, enable All Objects.
               All objects in the scene,
                  as well as any object you subsequently create, are included in the
                  selected output.
                
To set the visibility of an object:
         
         
            - Select an object from the Object List.
            
- From the Object Options box, select one
               of the following:
               
               
               NoteWhen the Output type is set to Normal or
                     Z-Depth, the objects in Occlude Only mode are rendered normally;
                     it will be part of the Normal or Z-Depth output. The Visibility
                     mode is ignored.
                   
To add or remove an object from the Objects list:
         
         
            - From the Edit Mode box, select Edit Output
               or press Alt+E.
               NoteIn Edit Output mode,
                     All Objects in the Object List is disabled when you remove objects
                     from the selected output.
                   
- Add or remove objects from the output
               by doing one of the following in the schematic: 
               
                  - Click an object. The complete tree of
                     the object in the schematic must either be selected or grayed out
                     for it to be included or excluded from the output.
                  
- Press Ctrl and
                     drag in the schematic to add or remove multiple objects (or trees)
                     from the output. This acts as a toggle between selected or grayed
                     out (included or excluded from the output).
                  
 
To set all objects to Visible mode:
         
         
            - Click Reset All. 
               All objects in the selected
                  output are set to the Visible mode.
