This page contains information about using shaderA program that runs on the GPU. More info
See in Glossary code blocks. For information about writing HLSL itself, refer to Writing HLSL shader programs.
HLSLPROGRAM and HLSLINCLUDE are compatible with all render pipelinesA series of operations that take the contents of a Scene, and displays them on a screen. Unity lets you choose from pre-built render pipelines, or write your own. More info
See in Glossary.
| Signature | Function |
|---|---|
HLSLPROGRAM[source code for shader programs]ENDHLSL
|
Creates a shader program block. Unity adds the HLSL shader program to the pass that includes this shader program block. |
HLSLINCLUDE[code that you want to share]ENDHLSL
|
Creates a shader include block. Unity includes this code in all shader programs that are defined in HLSLPROGRAM blocks, anywhere in this source file. |
CGPROGRAM and CGINCLUDE are compatible only with the Built-In Render Pipeline. For most uses, use HLSLPROGRAM and HLSLINCLUDE instead, unless you write surface shadersA streamlined way of writing shaders for the Built-in Render Pipeline. More info
See in Glossary.
If you use CGPROGRAM, Unity includes several of Unity’s built-in shader include files by default, enabling you to use built-in variables and functions. As a result, shaders that use CGPROGRAM might not work if you change the keyword to HLSLPROGRAM.
Note: Although the shader library files in the Built-In Render Pipeline have a .cginc file extension, they contain HLSL code rather than CG code.

CGINCLUDE[code that you want to share]ENDCG
|
Create a shader include block. Unity includes this code in all shader programs that are defined in CGPROGRAM blocks, anywhere in this source file. |
