# ShaderCompilerPlatform

> Shader compiler used to generate player data shader variants.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEditor.Rendering](/engine/6000.0/script-reference/unityeditor/rendering.md)
* **Assembly:** UnityEditor

```csharp
public enum ShaderCompilerPlatform
```

## Remarks

In Unity, shader programs are written in a variant of [HLSL](/engine/6000.0/manual/materials-and-shaders/shaders/writing-custom/shader-writing/sl-shading-language.md) language.

Each [platform](/engine/6000.0/manual/platform-specific.md) supports one or multiple graphics APIs. For example, Vulkan and Direct3D 12 are both supported in Windows. When building a standalone player, for each supported graphics API, Unity runs a corresponding shader compiler which generates the shader variants and cross-compiles the shader snippet into the shading language natively supported by the graphics API.
