SubShader block in ShaderLab reference

To define a SubShader in ShaderLabUnity’s language for defining the structure of Shader objects. More info
See in Glossary, you use a SubShader block. This page contains information on using SubShader blocks.

Inside the SubShader block, you can:

• Assign a LODThe Level Of Detail (LOD) technique is an optimization that reduces the number of triangles that Unity has to render for a GameObject when its distance from the Camera increases. More info
  See in Glossary (level of detail) value to the SubShader, using the LOD block. See assigning a LOD value to a SubShader.
• Assign key-value pairs of data to the SubShader, using the Tags block. See ShaderLab: assigning tags to a SubShader.
• Add GPU instructions or shaderA program that runs on the GPU. More info
  See in Glossary code to the SubShader, using ShaderLab commands. See ShaderLab: using commands.
• Define one or more Passes, using the Pass block. See ShaderLab: defining a Pass.
• Specify package requirements using the PackageRequirements block. This makes Unity only run the SubShader if the required packages are installed. See ShaderLab: specifying package requirements.
