Well I can't be the only one that wants it, some of us have campaigns based in entirely different worlds and I (f. ex, amongst other things) need to have werewolves, or a giant starfish, or a nasty imp (familiar of a powerful lich mage) , just to name a few. So creating a system like this, saying that "you can do your own D&D campaigns in the divinity engine" and not giving tools to create a comfortable pipeline is just a bad move.
I'm with you. I would like to use creature coming from the D&D world and my first idea was to extract models/texture from NWN and NWN2 and import them in D:OS 2. I hope this will be somehow possible ( especially cause i'm bad at 3d modeling )
