This modification replaces the default SCS weather definitions with reworked fog systems, enhanced atmospheric depth haze, refined colour balance, adjusted skybox colourways, and improved environmental lighting for a more immersive and natural driving experience.
Version 2.1 focuses on improving the existing Weather 2.0 base with better contrast balance, exposure fixes, world colourway changes, and improved rain intensity and atmosphere.
The skyboxes have not been redesigned, but professionally adjusted in colour balance, atmosphere blending, lighting behaviour, contrast, and exposure to improve environmental depth while staying within SCS engine limits.
