god I wish I had a working computer I'd organize one of my maps... Its the one whereas the shadows being cast are aligned with the sun, and I also got alot of sun beams (Whenever you look up at the sun, sometimes you can see the circles and beams from the brightness)
so that way when you look at the sun its pretty bright, I set up 24 of them in this one map whereas where ever you walk it gets triggered on and then off then another on, that way it doesn't mater where your at, you look at the sun and its bright, very realistic, when I last was finishing it I was using the same concept of making a rainbow in a waterfall... It is still my favorite peice of work for realism.
