# Preparing Sprites For Lighting
To light __Sprites__ with __2D Lights__, the [Sprite Renderer](https://docs.unity3d.com/Manual/class-SpriteRenderer.html) component of the Sprite is assigned a material with a Shader that reacts to 2D Lights. With the 2D Lights preview package installed, dragging Sprites onto the Scene automatically assigns the Sprite-Lit-Default material to them which enables them to interact and appear lit by 2D Lights.
Alternatively, you can create a custom Shader that reacts to Lights with the [Shader Graph package](https://docs.unity3d.com/Packages/com.unity.shadergraph@5.6/manual/Getting-Started.html). The Shader Graph package is available for download via the Package Manager.
## Upgrading to a compatible Shader
If you are installing the 2D Lights package into a Project with pre-existing Prefabs, materials or Scenes, you will need to upgrade any materials used to a lighting compatible Shader. The following functions automatically upgrade a Scene or Project automatically in a one way process. Upgraded Scenes or Projects cannot be reverted to their previous state.
### Upgrading a Scene
To upgrade the currently opened Scene, go to __Edit> Render Pipeline > UniversalRP 2D Renderer > Upgrade Scene To 2D Renderer__
### Upgrading a Project
To upgrade all Prefabs and materials in your Project, go to __Edit > Render Pipeline > UniversalRP 2D Renderer > Upgrade Project To 2D Renderer__
