# Editing cel attributes

This section discusses how to edit the attributes of a 3DO cel using the Attributes editor from the Window dialog. The Attributes editor lets you set certain Cel Control Block (CCB) flags for a cel. The Attributes are discussed in detail in 3DO PostPro Reference.

For background information on CCBs see see Introduction to 3DO Graphics.

To display the attributes dialog and edit its options, follow these steps:

1. Launch 3DO PostPro.

2. From the File menu, choose Open; then select the cel you want to work with from the Open dialog. The Document window appears (see Figure 1).

4. Double-click on the Attributes category listing in the Document window. The Attributes editor appear (see Figure 2).

5. Change the attributes using the options on the pulldown menus. As you make changes, you can view the effects immediately on the Workbench and on the television display monitor.

6. When you are satisfied with your changes, save the file. Choose Save to save under the same name as the original cel, or Save As to save it under a new name.
