## DisableKeyword(GlobalKeyword)

Adds a command to disable a global or local shader keyword.

```csharp
public void DisableKeyword(in GlobalKeyword keyword)
```

### Parameters

**** (\[GlobalKeyword]\(/engine/6000.6/script-reference/unityengine/rendering/globalkeyword)): The global or local shader keyword to disable.

### Remarks

Shader keywords determine which shader variants Unity uses.

## DisableKeyword(Material, LocalKeyword)

Adds a command to disable a global or local shader keyword.

```csharp
public void DisableKeyword(Material material, in LocalKeyword keyword)
```

### Parameters

**** (\[Material]\(/engine/6000.6/script-reference/unityengine/material)): The material on which to disable the local shader keyword.**** (\[LocalKeyword]\(/engine/6000.6/script-reference/unityengine/rendering/localkeyword)): The global or local shader keyword to disable.

### Remarks

## DisableKeyword(ComputeShader, LocalKeyword)

Adds a command to disable a global or local shader keyword.

```csharp
public void DisableKeyword(ComputeShader computeShader, in LocalKeyword keyword)
```

### Parameters

**** (\[ComputeShader]\(/engine/6000.6/script-reference/unityengine/computeshader)): The compute shader for which to disable the local shader keyword.**** (\[LocalKeyword]\(/engine/6000.6/script-reference/unityengine/rendering/localkeyword)): The global or local shader keyword to disable.
