Directional Light

Directional Light emits light equally in all directions and gets dimmer the farther it is from the source. Use this to simulate light from a lamp or light bulb.

Add a Directional Light Component

Add a Directional Light component by clicking + Add Component > Scene > Directional Light in the Inspector panel.

Properties

Property	Description
Intensity	The brightness of the light source.
Color	The color of the light.
Cast Shadow	Determine whether or not this light casts shadows.
Resolution	The x and y resolution of your shadow map. Only available if Cast Shadow is enabled.
Strength	Set the darkness of your shadow. Only available if Cast Shadow is enabled.
Advanced Settings	Only available if Cast Shadow is enabled. Bias: Shift pixels closer to the light source in your scene, helping combat shadow acne. The bias property should be used with caution, as too much bias will cause your shadows to “float away” – a phenomenon called Peter Panning. Color: The color of your shadow. Black is the default color. Self Gradient: Aid transition to a smooth surface by adding a value that helps counter jagged or hard edges. Soft Shadow: Control whether or not your shadow is blurred at the edges.
Layers	Select the layer or layers you want to apply the light to.

note

A maximum of three Directional Lights can be added to the scene.
