Ambient Bundle/Plugin idea(Weather effects)

Hi!

Would be great if we had an option to change/add weather effects, fog colours and swimming on/off per map!

Effects such as: rain, snow,  heavy snow, sandstorm, leaf fall, water/bubbles etc. 

Fog colours similar to glow.bmd where we could change colours of the fog per map and perhaps distance when zoomed out with the 3D cam to hide the pop in distance?

Void image addon for maps so we can have a reflection effect instead of the black void(Acheron - Nars map).

This would help for more customs to be made and create more freshness to the game.
