Sky & sun

The sky

The background sky has two modes:

• Solid — a single flat colour. The default is a soft, neutral grey.
• Gradient — a two-colour blend from top to bottom.

The sun

Every scene starts with a sun — a directional key light, so nothing is ever unlit. The sun is a normal light you can select, drag with the gizmo and adjust in the inspector: its colour, intensity and direction, and whether it casts shadows. It cannot be deleted, so your scene always has a light to build from.

An ambient light fills the shadows; control its intensity (0–4) and colour separately from the sun.
