Note
Parametric Lights are available from Version 2023.2.
In addition to the default HDRI lights, version 2023.2 supports Parametric Lights. Parametric Lights provide the ability to create custom lights which improve the overall look of the render output. Using Parametric Lights reduces dependency on HDRI which requires more computing power for Unreal.
When using Parametric Lights, bear in mind that the direction of the light source is determined by setting the angle of the lights source. The following custom lights are supported:
Area light: The light source is projected in a specific direction, in a rectangular shape. This light source can be compared to a window where through which light shines in.
Spotlight: A light source projected in a specific direction, in a circular shape. This light source mimics the light in a studio or on a stage. The light source fades away at the edges.
Directional Light: A strong light source, like the sun. The light source is from a specific direction and angle, without a specific shape and projects light endlessly in all directions.
Point Light: Similar to a regular light bulb, this light source has no specific direction, shape or angle and projects light in all directions.
