Create a 2D light in URP
Create a 2D light in the Universal Render PipelineA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary (URP). 2D lights illuminate compatible 2D GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info
See in Glossary in your sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary.
Follow these steps:
Right-click in the Hierarchy window, then select Light.
-
Select one of the built-in 2D light types. The types are:
- Spot Light 2D: Emits light from a point in a specific direction with a cone-shaped area of effect.
-
SpriteA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info
See in Glossary Light 2D: Emits light in the shape of a sprite. - Freeform Light 2D: Emits light as a custom polygon shape that you can edit.
- Global Light 2D: Lights all 2D GameObjects equally with no attenuation. You can only use one global light per blend style and sorting layer.
If you create a custom 2D light type, the custom light type also appears in the list.
Avoid self-intersection in Freeform lights
If you create a Freeform Light 2D, the light might not appear in areas where the light overlaps with itself.
To avoid this, do the following:
- Make sure the edges of the shape don’t cross over each other.
- Set the Falloff properties of the light to ensure the light doesn’t overlap itself.
