## RemoveVariant(Shader, PassIdentifier, LocalKeyword\[])

Remove [ShaderVariantCollection.ShaderVariant](/engine/6000.7/script-reference/unityengine/shadervariantcollection/shadervariant.md) and associated graphics states from collection.

```csharp
public bool RemoveVariant(Shader shader, PassIdentifier passId, LocalKeyword[] keywords)
```

### Parameters

**** (\[Shader]\(/engine/6000.7/script-reference/unityengine/shader)): Shader used in the variant.**** (\[PassIdentifier]\(/engine/6000.7/script-reference/unityengine/rendering/passidentifier)): PassIdentifier used in the variant.**** (\[LocalKeyword\[]]\(/engine/6000.7/script-reference/unityengine/rendering/localkeyword)): [LocalKeyword](/engine/6000.7/script-reference/unityengine/rendering/localkeyword.md) array of keywords used in the variant.

### Returns

| Type                                                          | Description                                    |
| ------------------------------------------------------------- | ---------------------------------------------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | True if successfully removed, false otherwise. |

### Remarks

If only the `material` is provided, then this function will only remove a shader variant matching exactly the set of [Material.enabledKeywords](/engine/6000.7/script-reference/unityengine/material/enabledkeywords.md) combined with the global shader keywords that are **currently enabled** in the active context, unless they are explicitly provided via `globalKeywords`.

```

### Parameters

**** (\[Material]\(/engine/6000.7/script-reference/unityengine/material)): **** (\[PassIdentifier]\(/engine/6000.7/script-reference/unityengine/rendering/passidentifier)): PassIdentifier used in the variant.

### Returns
