Not bad mod. 2 years ago, suffering in the hot days of may, i made a winter mod for LFS 0.2. Then i thought about making it for all the S1, but gave up. At the first attempt I made background walls of trees just black&white. That looked poorly, because at the track colors were shifted in many places, so there were green and orange walls of wood. At the second attempt I tried to put there pine-trees wall instead of broad-leaved trees (because it's winter, yes?
), but the problems with colors were even worse, the wall looked unnatural and worse than in the old NFS1 or maybe Doom-1. Wish you success. But don't make everything more gray/white.
Here is my old movie with LFS 0.2 and winter textures.
