Typical Scottish summer time. My entire summer holiday from work resembled this.
I've come across a nice idea with TG clouds while playing with this. I'm WIP'ing my mammatus again, I'll post updates later...

Thanks for etc! ;)
I like it. You would feel right at home here in Binghamton NY. We have had the same summer. Since I do not like 80 degrees plus, it has been good.
looks nice, nice stormy weather. :)
the weather looks about the same down here.
nice sky Oo
Those clouds are truly awesome - hope you will give us some tips!
Very nice bud!
Nice sky! However I find it slightly depressing compared to the 85 degress it is outside where I am :P
Wow, the clouds and lighting in the sky is very very good! Looking forward to see your next iteration!

Thanks, folks. And yes, it is depressing. :(
There is also no GI at all in this image.
Dombib: A tip, of course... I checked 'flatter base', without ANY added 'base softness'. Raised coverage until no blue sky was visible. This should make a flatish base to the entire cloud layer.
The next part is the key to the lighting. By checking 'invert profile', you turn this very flat base towards the sun and the top of the cloud towards the ground.
The pretty much nice-and-flat 'surface' of the complete-cover cloud layer distributes the lighting really well.(it doesn't work as well for sparse cloud because you can obviously see the flat top of every cloud.
The deeper you now make the cloud - the closer to the ground the 'fingers' stretch. Mammatus pending... ;)
Fill lighting comes from 2 suns, 0.25 strength, behind the pov.
My camera always faces North, except tilt/height it really never moves from my default position, a few metres here and there. I build the scene around the POV, never the other way around so, a simple set of 3, no shadow, suns set at 0, 120 and 240 degrees fits any scene I make. I just disable/enable them to suit the scene when I can't afford the GI time.
So, you have your own default scene. I have tried fill lights, but they always seemed too bright. But then FrankB would like that. I think my aversion to bright scenes comes from working at night. Bright sun bothers my eyes now.
those clouds are awesome!
Very clever cloud set-up - thanks for sharing! As it happens, I'm working at the moment on a scene with no clouds, trying to get a realistic clear blue sky to mimic a photo. This is actually quite difficult, given the number of parameters that affect sky colour - e.g. I was surprised to find that the bluesky horizon colour actually has to be quite grey to match the photo. I was wondering if your 'double atmosphere' set-up, as in your pyramid image, might be useful, but I've no idea how to go about using such a set-up. Any suggestions?
The boiling look to these are really cool!!!
Thelby: I'd probably(if I needed to) create a second atmo node, plug it in between the first one and the planet and then disable the new one's bluesky/redsky density/decay(setting one of them to zero will disable the other, aswell). Then I'd just use the haze parameters to fill the original atmo with the desired colour.
In your height control tab, set the 'haze exp height' to a suitable height(my pyramids image second atmo has an exp height of about 2m, I think).
You shouldn't really need a second atmosphere to make an empty blue sky, though. I do see why you'd consider it, the linked parameters in the atmo node bother me aswell, I'd like to set the 'tweaks' colours independently, too.
The moon in my bedtime for birds image has another 2 haze-only atmospheres on it, making the glow, a pinkish one, and a fainter bluish one, too. Insane values for haze exp height make it spread across the sky. This just makes it appear to be lighting up the default atmosphere. I'd recommend setting the exp height to '100,000m' then adding an extra zero incrementally until you see it spread across the sky, it'll probably become far too big by '1000,000m' so then I'd adjust the '1000,000' to '500,000' etc. until I have it at the level I want.
Just play around! :)

Internally they are only one parameter, so that's not possible. In v0.9 they were separate because there was no direct control over horizon colour, and the horizon colour was implied by the relationship between the bluesky density and redsky decay colours. For TG2 I thought it was more useful to control the the horizon colour directly, but to add that control there has to be only one density or decay colour. There are still two degrees of freedom, just parametrised differently. I still allow you to see the density and decay colours and change them by editing one of them, but they have to be locked in a relationship so that horizon colour stays the same.
Internally linking all these parameters is already fairly complex because I've tried to make it as controllable as possible, so I'm afraid there's no possibility of making it optional which method you choose, or allowing you to change one of the density or decay colours and auto updating the horizon colour. Sorry about that.

Thanks for the post, Matt. There is still the option of disabling the red/blue sky colours so, it doesn't really put me up nor down. If I need to use 2 atmos with 2 different haze colours then so be it. That is great.
You can't add a double atmosphere in any other app I own or have used, TG still is King. It's just so pliable to any of my needs, almost. :)
