Fog, low visibility,haze and clouds level.

[SIMBIOX]

Please, let us add a fog effect, Short range haze to simulate low visibility conditions in BOS mission editor. 
Before this new cloud system we faked this effect lowering the clouds base level to the GND level, but now it does't work.
Enhaced haze parameter whith near-to-plane low visibility could be great.
THANKS?
