@mrwallace888 It's not about the trainer, it's the timecycle file. If you use a different timecycle for w_xmas.xml , then the fog will gone. Let me know if you find a modded w_xmas.xml with a beautiful volumetric fog like the original vanilla xmas.
@centralsink You will need to remove the car generators from the spots you want them gone. You can use CodeWalker to do that. You can get the latest version of CW from the CW discord since the one on gta5-mods is outdated.
