Sprite Lit shader graph reference for URP

Explore the properties and settings you can use to customize the default Sprite Lit shader graph in the Universal Render Pipeline (URP).

For more information about 2D shaders in URP, refer to 2D Lighting in URP.

Contexts

The default Vertex and Fragment Contexts contain the following Blocks. Which Blocks display might change depending on the graph settings.

Vertex Context

The default values are the values from the mesh.

Input	Type	Description
Position	Vector3	Sets the vertex position in object space.
Normal	Vector3	Sets the normal of the vertex in object space.
Tangent	Vector3	Sets the tangent of the vertex in object space.

Fragment Context

Input	Type	Description
Base Color	Vector3	Sets the base color of the material. The default is `Color.grey`.
Sprite Mask	Vector4	Sets a custom mask that determines whether the pixels of the sprite are visible. For more information, refer to Add normal map and mask textures to a sprite.
Normal (Tangent Space)	Vector3	Sets a custom normal map to simulate bumps and grooves on the surface of the sprite. For more information, refer to Add normal map and mask textures to a sprite.
Alpha	Float	Sets the alpha of the material. The range is 0 to 1. The default is 1.
Alpha Clip Threshold	Float	Sets the minimum alpha value for a pixel to be visible. The range is 0 to 1. The default is 0.5. This property is only available if you enable Alpha Clipping in the graph settings.

Graph Settings

Explore the shader graph settings you can use to customize the Fragment and Vertex contexts.

For more details about graph settings that are common to all shader graph shaders, refer to Graph Settings tab.

Setting	Description
Blending Mode	Sets how the shader blends the color of a transparent material with the background. The options are: Alpha: Calculates transparency using the alpha value of the material. Premultiply: Calculates transparency using the alpha value of the material, but multiplies the RGB values by the alpha value first. Additive: Adds the color of the material to the background color. Multiply: Multiplies the color of the material with the background color. For more information about blending modes, refer to Blend modes.
Depth Write	Determines whether the shader writes depth information to the depth buffer. The options are: Auto: Sets opaque objects to write to the depth buffer, and transparent objects to not write to the depth buffer. Force Enabled: Enables all objects from writing to the depth buffer. Force Disabled: Disables all objects from writing to the depth buffer.
Alpha Clipping	Discards pixels if their alpha value is lower than a threshold value. Enabling this setting adds the Alpha Clip Threshold Block to the Fragment context.
Disable Color Tint	Prevents Shader Graph tinting the sprite with the Color property of the sprite. If you enable this setting, use a Vertex Color Node to access the Color property of the sprite.
Sort 3D as 2D Compatible	Uses 2D sorting rules to draw 3D objects, to avoid 2D objects appearing at the wrong depth.
Custom Editor GUI	Renders a custom editor GUI in the Inspector window of the material. Enter the name of the GUI class in the field. For more information, refer to Control material properties in the Inspector window.
