derive/mo_name/master_mo/ mo_name is type character, required.
master_mo is type character, default is -cmo-
Uses Mesh Object, master_mo, as the template for deriving Mesh Object, mo_name. Mesh Object, mo_name, will be an image of master_mo but will contain no data. The output Mesh Object, mo_name, will become the Current Mesh Object. If mo_name is the same as master_mo nothing happens. If mo_name exists it is over written.
