Displacement Mode

This setting controls the method that the High Definition Render Pipeline (HDRP) uses to displace Materials.

Options

The options in the Displacement Mode drop-down change depending on the Shader you use.

Lit Shaders

Drop-down option	Description
None	Select this option to apply no displacement to the Material.
Vertex displacement	Select this option to displace the Mesh’s vertices according to the Height Map.
Pixel displacement	Select this option to displace the pixels on the Mesh surface according to the Height Map.

Tessellation Shaders

Drop-down option	Description
None	Select this option to apply no displacement to the Material.
Tessellation displacement	Select this option to displace the Mesh’s surface according to the Height Map. Tessellation Shaders subdivide the Mesh and add vertices according to the Material’s tessellation options. Tessellation displacement also affects these vertices.

Shared Properties

Property	Description
Lock with object scale	Enable the checkbox to alter the height of the displacement using the Scale of the Transform. This allows you to preserve the ratio between the amplitude of the displacement and the Scale of the Transform.
Lock with height map tiling rate	Enable the checkbox to alter the amplitude of the displacement using the tiling of the Height Map. This allows you to preserve the ratio between the amplitude of the displacement and the scale of the Height Map Texture.

Pixel Displacement

Property	Description
Minimum steps	Use the slider to set the minimum number of Texture samples which Unity performs to process pixel displacement.
Maximum steps	Use the slider to set the maximum number of Texture samples which Unity performs to process pixel displacement.
Fading mip level start	Use the slider to set the mip level at which the pixel displacement effect begins to fade out.
Primitive length	The length of the Mesh (in meters) on which Unity applies the displacement mapping.
Primitive width	The width of the Mesh (in meters) on which Unity applies the displacement mapping.
Depth Offset	Enable the checkbox to modify the depth buffer according to the displacement. This allows effects that use the depth buffer (Contact Shadows for example) to capture pixel displacement details.

Surface Inputs

Shared Properties

Property	Description
Height Map	Assign a Texture that defines the heightmap for this Material. Unity uses this map to apply pixel or vertex displacement to this Material’s Mesh.
- Parametrization	Use the drop-down to select the parametrization method for the to use for the Height Map. •Min/Max: HDRP compares the Min and Max value to calculate the peak, trough, and base position of the heightmap. If the Min is -1 and the Max is 3, then the base is at the Texture value 0.25. This uses the full range of the heightmap. •Amplitude: Allows you to manually set the amplitude and base position of the heightmap. This uses the full range of the heightmap.
- Min	Set the minimum value in the Height Map.
- Max	Set the maximum value in the Height Map.
- Offset	Set the offset that HDRP applies to the Height Map.
- Amplitude	Set the amplitude of the Height Map.
- Base	Use the slider to set the base for the Height Map.
