how good quality is subjective

- i'd suggest trying the above d/l as a quick way to look.
Basically it has potential- when it gets 'finished' in BO? (the sequel whatever it's to be called) -and it no longer causes frame rates to fall through the floor
atm it only draws out a certain distance from player's plane so that it works quite well with a small height difference. However if you are at 20,000 feet and the clouds are at 2000 feet then it looks like a patch of cloud following you.
There is also some flickering of cloud textures at times.
Like I said in previous post this is not a supported feature,
While we're talking weather there is also wind to consider:- found in 'mission parameters' Flow tab(s)- you can create your own with different winds at different heights.
Just to be difficult the orientation isn't logical- ) deg=west and + degrees is anticlockwise

This is apparently on a list of things to be corrected at some point by the devs.
Oh yeah, AI can see through clouds
