Create a custom 2D light type

Light2DProvider

1. In a C# script, create a class that inherits from

   Light2DProvider

   .
2. Implement the

   ProviderName

   method and return a

   GUIContent

   object with your name for the new light type. The name appears in the Light Type property of the Light 2D component reference for URP. For example:

   using UnityEngine;using UnityEngine.Rendering.Universal;[System.Serializable]public class QuadLight : Light2DProvider{    public override GUIContent ProviderName() {        return new GUIContent("My Quad Light");    }}

3. Implement the

   GetMesh()

   method to return a mesh that defines the shape of the light.
4. To create custom parameters, add a serialized field to the class. For example:

   [SerializeField] float size = 1f;

5. Select an existing 2D light in the Hierarchy view, then change Light Type to your new type. The serialized field appears in a new Provider section in the

   Inspector

   ?

   window.

Example

using UnityEngine;using UnityEngine.Rendering.Universal;[System.Serializable]public class MyTriangleLight : Light2DProvider{    public override GUIContent ProviderName() => new GUIContent("Triangle Light");    [SerializeField] float scale = 0.5f;    public override Mesh GetMesh()    {        Mesh triangleMesh = new Mesh        {            vertices = new[]            {                new Vector3(-scale, -scale, 0f),                new Vector3(scale, -scale, 0f),                new Vector3(scale, scale, 0f),            },            triangles = new[] { 0, 1, 2 }        };        triangleMesh.RecalculateBounds();        triangleMesh.RecalculateNormals();        return triangleMesh;    }}
