You must authorize character studio 3 before you can use it to create character animations. The first time you create a biped, a crowd, or apply Physique to a skin, the software displays an authorization dialog.
Instructions for authorizing your copy of the software are on the registration card included in the product package.
Note: Your copy of character studio is tied to the 3D Studio MAX lock you use during the authorization process. Be sure to authorize character studio on the 3D Studio MAX installation where you plan to use the product. If you change or replace locks, you will need a new authorization code.
