To be same as in multilight, one parameter for sun only secondary for sky only.
Now sun parameter inside Maxwell controls sky brightness too.

Hello AlexP and arch3d,

Yes, the brightness of the atmosphere is a consequence of the brightness of the Sun, obviously, as it should, and this is the way the Physical Sky model in Maxwell works.

BUT as we know you usually want to get different results, just simply enable MultiLight and you will get one separated slider for the Sun intensity and another independent slider for the Sky intensity, like you are asking.

You already have it!

Dario, we know!
Just suggesting to separate that slider to get consistent interface.

I don't get it. If it's already there what are you asking for? There are two sliders already.

[AlexP]

Fernando, in studio/plugin interface when you change sun value sky value changes too as dariolanza wrote. In multilight changing sun value changes only sun light, not sky (much better solution). We have now two sliders, but now to change sun value you have to e.g. increase sun value AND decrease sky value.

[Fernando Tella]

Oh, I get it. You can lower sky value, but if you lower sun, sky lowers too.

[dariolanza]

It is done this way because it is the only physically correct way to calculate the atmosphere.

An slider that could lower the Sun intensity while increate the Sky intensity before the render would break completely the Physical Sky model, as the atmosphere brightness is obviously a consequence of the Sun intensity.

The only think that we can allow while preserving the correctness of the model would be adjust it with the MultiLight sliders, so in post, after the contribution of those two buffers where calculated.

Believe me that although breaking the correctness of the sky model would sound nice here, it would generate further problems in other cases.
