Light and Shadow

Light

The lights in your scene inform the lighting, and therefore the shading, of materials that utilize scene lights. Learn more about Simple Lighting and Standard PBR material. These lights can create specular highlights and optionally cast shadows.

Add a Light Object

You can add a Light object to the scene by clicking + > Scene and selecting one of the available light types. Alternatively, you can add a light by right-clicking in the Hierarchy panel, hovering your mouse over Scene, and clicking the type of light you want to add.

Inner Angle: The angle of the inner attenuation which informs the beginning of the light spot.

Outer Angle: The angle of the outer attenuation which informs how far out the edge of the spot light will extend towards.

Point Light

A Point Light is a point in 3D space that sends light out equally in all directions.

Point Light Properties

Intensity: Determine how bright the light source is.
