I did a bit of hunting but so far have not found any camera mods for Two Worlds. Specifically, I'm finding I get vertigo with the close-in camera and would love to have a camera unlock that would allow me to move my point of view to, say, 10-20 feet (3-7 m) above and behind the PC. Otherwise I can't play for more than 20 minutes or so without having to take a break to reset my eyes and stomach. Anyone know of such an animal?

I don't have the game installed right now, so I cant double check for you, but I thought that that feature was built into the game. I remember there being controls that would zoom the camera in and out. You could just zoom way out and play like that. I have found that I do remember a lot of stuff that isn't true though.

You can zoom with the tab key and you can also zoom with the mouse whell unless you have set it to control the spell selection.
But maybe the OP want to zoom farther away.

Yes, I am looking for something that allows a farther zoom out than the built-in mouse wheel control. The maximum zoom built in still isn't quite enough to eliminate the vertigo---crossing hillsides really makes it set in because the camera wants to tilt erratically at times because of the terrain. If I could get it out to about twice the max distance I think it would solve the problem. Still enjoying the game, I just have to play in short segments.
