Enabling the Lighting System in Untold Engine

The Lighting System lets you add illumination to your scenes using common real-time light types. Under the hood it wires up the required ECS components, provides an editor-friendly visual handle, and tags the light so the renderer can pick it up.

Creating Each Light Type

Directional Light

Use for sunlight or distant key lights. Orientation (rotation) defines its direction.

let sun = createEntity()
createDirLight(entityId: sun)

Point Light

Omni light that radiates equally in all directions from a position.

let bulb = createEntity()
createPointLight(entityId: bulb)

Spot Light

Cone-shaped light with a position and direction.

let spot = createEntity()
createSpotLight(entityId: spot)

Area Light

Rect/area emitter used to mimic panels/windows; position and orientation matter.

let panel = createEntity()
createAreaLight(entityId: panel)
