Improved Lighting by Shimrod101 at Mod The Sims

This mod improves the lighting primarily indoors, and alters outdoor lighting a bit also. Indoors will be brighter than the default overall and Ambient light is spread throughout so walls will not be as dark and sims facing away from the light source will not be as dark.
Sunlight entering through windows is greater than the default. Also the SS Ambient Occlusion is increased such that objects everywhere have a little more contrast and/or depth; the washed-out look of the entire game graphics is reduced a bit.
