Actually, if you want to take the time to relight the ojaroad map, it looks quite nice.
Running PlaneShift normally, travel to the ojaroad map, then quit. Open up a command prompt, change to the directory containing the PlaneShift binaries, and enter the command psclient -relight (or whatever the equivalent for your operating system is). Log in.
Go eat a meal or something (on a 3GHz machine, it took about 14 minutes to complete; on a 1.8GHz box, 33 minutes).
Once it\'s finished, exit and run PlaneShift normally (otherwise you\'ll have to wait for a relight every time you cross into a different map).
