Hair

The Hair Master Stack enables you to render hair and fur in the High Definition Render Pipeline (HDRP). To create a realistic looking hair effect, it uses layers called hair cards. Each hair card represents a different section of hair. If you use semi-transparent hair cards, you must manually sort them so that they are in back-to-front order from every viewing direction.

Creating a Hair Shader Graph

To create a Hair material in Shader Graph, you can either:

• Modify an existing Shader Graph.

  1. Open the Shader Graph in the Shader Editor.
  2. In Graph Settings, select the HDRP Target. If there isn't one, go to Active Targets, click the Plus button, and select HDRP.
  3. In the Material drop-down, select Hair.

• Create a new Shader Graph.

  1. Go to Assets > Create >Shader Graph > HDRP and click Hair Shader Graph.

Contexts

[!include]

Vertex Context

Default

When you create a new Hair Master Stack, the Vertex Context contains the following Blocks by default:

[!include[](snippets/shader-graph-blocks/vertex-position.md)] [!include[](snippets/shader-graph-blocks/vertex-normal.md)] [!include[](snippets/shader-graph-blocks/vertex-tangent.md)]

Property	Description	Setting Dependency	Default Value

Relevant

This Master Stack material type adds all its Vertex Blocks to the Vertex Context by default and has no extra relevant Blocks.

Fragment Context

Default

When you create a new Hair Master Stack, the Fragment Context contains the following Blocks by default:

[!include[](snippets/shader-graph-blocks/base-color.md)] [!include[](snippets/shader-graph-blocks/normal-tangent-space.md)] [!include[](snippets/shader-graph-blocks/bent-normal.md)] [!include[](snippets/shader-graph-blocks/hair-strand-direction.md)] [!include[](snippets/shader-graph-blocks/transmittance.md)] [!include[](snippets/shader-graph-blocks/rim-transmission-intensity.md)] [!include[](snippets/shader-graph-blocks/smoothness.md)] [!include[](snippets/shader-graph-blocks/ambient-occlusion.md)] [!include[](snippets/shader-graph-blocks/alpha.md)] [!include[](snippets/shader-graph-blocks/specular-tint.md)] [!include[](snippets/shader-graph-blocks/specular-shift.md)] [!include[](snippets/shader-graph-blocks/secondary-specular-tint.md)] [!include[](snippets/shader-graph-blocks/secondary-specular-shift.md)] [!include[](snippets/shader-graph-blocks/emission.md)]

Property	Description	Setting Dependency	Default Value

Relevant

Depending on the Graph Settings you use, Shader Graph can add the following locks to the Fragment Context:

[!include[](snippets/shader-graph-blocks/alpha-clip-threshold.md)] [!include[](snippets/shader-graph-blocks/alpha-clip-threshold-depth-postpass.md)] [!include[](snippets/shader-graph-blocks/alpha-clip-threshold-depth-prepass.md)] [!include[](snippets/shader-graph-blocks/alpha-clip-threshold-shadow.md)] [!include[](snippets/shader-graph-blocks/baked-back-gi.md)] [!include[](snippets/shader-graph-blocks/baked-gi.md)] [!include[](snippets/shader-graph-blocks/depth-offset.md)] [!include[](snippets/shader-graph-blocks/normal-object-space.md)] [!include[](snippets/shader-graph-blocks/normal-world-space.md)] [!include[](snippets/shader-graph-blocks/specular-aa-screen-space-variance.md)] [!include[](snippets/shader-graph-blocks/specular-aa-threshold.md)] [!include[](snippets/shader-graph-blocks/specular-occlusion.md)]
