Ok (merci !!) thanks dave_baer I start the tute Dog and after that i uninstall MaYa. it's a great and wonderfull program but i don't have money to buy a license so i uninstall it and i return on gMax software after have finished the dog. But i stay on this forum and admire all artist here, just for look. for an obvious raison my english is a disaster (i'm french lol). so i'll be very unassuming. (its hard for me , i don't find the word lol "discret" in french) thank a lot bye
