dude just pm makman, cuz hes very busy. i was doing the same thing you were at one time. got some advice from him and everything. if i still had the files and the colors and textures id give them to you. i had seperate files for the medaterain and the atlantic north and south and i was going to make it to where during the seasons it would change but i got as far as the colors of the skies and then real life bit me in the butt and i had to get rid of my computer. good luck though man, makman probably will include it but thats not for me to decide. just contact him.
