- Tweak colors to be less saturated and more balanced (in terms of hue).
The cool blue sky is balanced by a warm brown ground,
which makes reflections look closer to how they'd look like when using
an HDRI panorama texture.
- Make the ground color dark on both ProceduralSkyMaterial and
PhysicalSkyMaterial to reduce indoor light leaking, especially
when using GI.
- Tweak the PhysicalSkyMaterial colors to be as close as possible
to ProceduralSkyMaterial (with the default sun orientation).
- Tweak editor environment defaults to be identical to the default
ProceduralSkyMaterial colors. Previously, the default editor sky
color was different from the colors of a newly created
ProceduralSkyMaterial resource.
Both new skies were tested without GI, with SDFGI and with VoxelGI.
They were tuned to look best when using ACES tonemapping with a
whitepoint set to 6, but they still look good with other
tonemapping operators.
