Customize shaders and materials

Create HDRP-specific material types, expose material properties, and manage shaders and materials.

Page	Description
Shader Graph in HDRP	Use Shader Graph to create material types specific to HDRP.
Create variants of materials	Use Material Variants to control and coordinate changes to variations of a source material.
Reduce shader variants	Make Unity strip more shader variants to avoid your build growing too big.
Custom material inspectors	Define how HDRP displays properties in the Material Inspector for a particular shader.
