Hi I had some posts before about it
we made sky color really desaturated and dark to keep shadow color less blue because for animation we cannot use diffuse it is too slow and still too noisy after 4000 samples per frame therefore we use AO only
We can get AO look almost like diffuse except for the sky color
please please add a separate sky color option that for color only and not shadow. Main one will affect shadow darkness and color and the other one you can just turn on and affects sky color only so we can make it more blue and pleasant looking but it will not affect shadow. Thank you
