its suppoesed to be 500,- Euro, thats actually cheap in the realms of professional applications. If it does what they say, then bigger studios won´t wait a second and even smaller ones will consider to buy.
I have Bodypaint integrated in Cinema4D, so for now I am fine. But I too will have a look at Mari. The minimum I hope is, that Maxon tries to keep on one level. Bodypaint has been the door opener to bigger studios for Maxon, so I guess they will have a close look.
