Note to Self

I've noticed that map sizes significantly decrease in size if lightmapping was occupying a large portion of that size. My first try was a level that went from 68.9MB (uncooked) to 45.5MB(cooked). In the newest revision I decided to be more liberal with the lightmap sizes, and got a map that was originally 77.5MB(uncooked) to get down to 47.9MB(cooked). If you were wondering about the math behind that, it's:

45.5MB / 68.9MB = .66

47.9MB / 77.5MB = .62

.62 + .66 / 2 = .64

This means that the lightmap size after cooking decreases by roughly 34%. Pretty nifty, indeed. I will definitely be using this formula for my next map to calculate file size :).
