Sky

Time of day is the control you will reach for most. It moves the sun, and everything in the world relights with it.

The panel also shows a Date readout and carries Latitude and Longitude. Those matter because they decide where the sun actually sits: the same time of day looks different at different latitudes, and that is what makes a world read as somewhere rather than nowhere in particular.

Day length sets how long a full day takes. A Time runs toggle decides whether the clock advances at all.

Turn Time runs off and the sky holds still at whatever hour you set, which is what you want while you are building. Turn it on and your world gets a day-night cycle.

Two sliders cover the air itself: Cloudiness and Haze.

Haze is worth knowing about even when you are not thinking about weather. If a world looks washed out and you cannot see distant terrain, haze is usually the reason, and turning it down is the fix.
