Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

I'm having a very tough time navigating in the city, within tall trees, or narrow dungeons with high walls.

Most of the time I have difficulty even seeing my character, I either see a wall, a tree, or etc.
I have tried different camera angles, but none seem to let me zoom out enough I can get above the walls of the city to see my PC.

Any advice appreciate!

Exploration Mode is the one you want to use.

There's a little check box hiding in the Options settings called "Object Fade". Find it, tick it, and love it as the game helpfully fades out any nearby object threatening to hide your character.
