Ok, I am going to post of few ideas I have had because I wasn't sure how stupid they were, but I have reached to the conclusion to just screw it and let you guys decide.
Lets begin with my superior artwork!

When doing outdoor scenes, how about having a point follow you character around. This point would then cast out rays which could help tell where to place shadows and reflections.
The point position would of course depend on the time of day. But the interesting part of this is shadows could fade by using eigenvector decomposition. So if you are standing on a cliff there wouldn't be a huge dark shadow all the way down. Plus if it were dusk and street lights were just coming on, you could use point ray casting on the street lights and do basic ray interference calculations to project 3 shadows.
Oh and you could put cubes around your points. And when two cubes intersect thats when you would start doing the ray calculations. Kind of like how collision detection is done.
