The Poser 5 page exists too !
Poser4 : Plenty of props (simples and smarts), some texture, characters (articulated props and clothes), poses (animated ones, body, hands, faces).... pictures, annimations and indeed everything in free downloads.
Be patients, as it's graphic world, it's rather slow...
Notice that in the pictures or animations shown, I never use background picture. That's 100% Poser.
(to download 421 animation (zip of .AVI(with sound)), click the picture)
Note : 421 is a 3 dices Pub game (and in French 3 dices has the same pronunciation as 3D)
