# SetKeyword

> Adds a command to set the state of a global or local shader keyword.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.Rendering](/engine/6000.0/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

## SetKeyword(GlobalKeyword, bool)

Adds a command to set the state of a global or local shader keyword.

```csharp
public void SetKeyword(in GlobalKeyword keyword, bool value)
```

### Parameters

**** (\[GlobalKeyword]\(/engine/6000.0/script-reference/unityengine/rendering/globalkeyword)): The local or global shader keyword to set the state for.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): The state to set the shader keyword state to.

### Remarks

Shader keywords determine which shader variants Unity uses.

## SetKeyword(Material, LocalKeyword, bool)

Adds a command to set the state of a global or local shader keyword.

```csharp
public void SetKeyword(Material material, in LocalKeyword keyword, bool value)
```

### Parameters

## SetKeyword(ComputeShader, LocalKeyword, bool)

Adds a command to set the state of a global or local shader keyword.

```csharp
public void SetKeyword(ComputeShader computeShader, in LocalKeyword keyword, bool value)
```

### Parameters

**** (\[ComputeShader]\(/engine/6000.0/script-reference/unityengine/computeshader)): The compute shader for which to set the state of the local shader keyword.**** (\[LocalKeyword]\(/engine/6000.0/script-reference/unityengine/rendering/localkeyword)): The local or global shader keyword to set the state for.**** (\[bool]\(https\://learn.microsoft.com/dotnet/api/system.boolean)): The state to set the shader keyword state to.
