>>714223347 (OP)While THAW's version of Minneapolis looks pretty good for a level from 1999. You can't possibly have that method of lighting work very well if you want to have dynamic lights from something like a car or a flash light on the skater or a day/night cycle.
That is kind of why objects and building textures abruptly load in and out in THUG1, THUG2, and THAW when the time of day changes. Although those levels are specifically meant to be viewed at different times of the day, while Minneapolis was always meant to be viewed at night.
