I've tested the camera function a bit:
As I mentioned in the video description, there are clearly a few problems. As far as the game is concerned, the camera hasn't changed; this causes a discrepancy between what the game renders and what you actually see. This has confirmed some of my suspicions regarding the way the game's rendering engine works. The area models of the room you are in are always rendered, for the most part; however, any creatures, doors, or placeables that you are not looking at directly aren't rendered at all, and the other rooms seem similarly dependent on your player's perspective. You can trick the game into rendering more by messing with camerastyle.2da but even this is limited.
Still, what it can do is rather rather handy. And I'm sure by testing with it further, we can resolve some of these issues. Excellent find!
