Write High-Level Shader Language (HLSL) vertex and fragment shader programs inside a

Pass

block in a custom ShaderLab shader.

Page	Description
Introduction to HLSL shader programs	Learn about writing shader programs in HLSL in Unity, and vertex and fragment shaders.
Add an HLSL shader program	Use the `HLSLPROGRAM` directive to add a shader program to a shader pass.
Reuse HLSL code	Include or duplicate HLSL in different places, or share `#pragma` directives across different shaders.
Input data into HLSL	Create a `struct` that declares shader variables and connects them to the vertex data of the mesh.
Sample a texture in HLSL	Declare and sample a texture in HLSL using a sampler.
Writing HLSL for different graphics APIs	Write HLSL to take into account how graphics rendering differs between different graphics APIs.
Use 16-bit precision in shaders	Use 16-bit precision in GPU calculations, so shaders use less memory, bandwidth, and power, and calculations are faster.
Pass information to the shader compiler	Use the `#define` , `#pragma` , and `#define_for_platform_compiler` directives to pass information to the shader compiler.
