Important: The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to the Universal Render Pipeline and Render pipeline feature comparison.
To define a SubShader in ShaderLab, you use a SubShader block. This page contains information on using SubShader blocks.
Inside the SubShader block, you can:
LOD block. See assigning a LOD value to a SubShader.Tags block. See ShaderLab: assigning tags to a SubShader.Pass block. See ShaderLab: defining a Pass.PackageRequirements block. This makes Unity only run the SubShader if the required packages are installed. See ShaderLab: specifying package requirements.To target a subshader at a specific render pipeline, use the RenderPipeline tag. For more information, refer to SubShader tags in ShaderLab reference.
