hello for 1: open Planeshift.cfg in planshift folder, change settings there.
2: sorry not shore. look in tech help thread there about it.
3: try this, start game when in game and you can move quit: then in terminal type: CD space followed by dropping planeshift folder in terminal window push return. then type:
./psclient.app/Contents/MacOS/psclient -relight push return.
This starts game when in game, quit close terminal, and restart game should have relight map of area you are in. (this may take some time depends on size of map to load)
This if needed will work for each area you find dark, temp work around till pssetup works.
Or if you still have .dmg 0.3.11 drag over and replace pssetup and pssetup .cfg they still work, with new set up.
Hope this helps, good luck.
