When
            specifying, for instance, a render file name, there is an option
            for entering UDAs in the string. The UDAs may be scoped or not and
            can be selected from the default lists available or can be created
            by the user. See—
                     Creating UDAs.
         
         To add a UDA to a render file name:
         
         
            - Open the Project Preferences window by
               clicking on the project icon in the task bar then select the Render
               tab.
            
- Click open the Select UDA menu and select
               the UDA you want to add to the File Name string. In this example
               the scoped Project:Art Director UDA is selected, loaded and ready
               to insert into the string. 
            
- Place the cursor in the File Name string
               where you want the UDA to appear and select UDA.
               The UDA is added to the
                  string.
                
- Repeat steps 2 and 3 to add more UDAs
               to the string.
