## IsPropertyLocked(int)

Checks whether a property is locked by this material.

```csharp
public bool IsPropertyLocked(int nameID)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Property name ID, use [Shader.PropertyToID](/engine/6000.0/script-reference/unityengine/shader/propertytoid.md) to get it.

### Returns

| Type                                                          | Description                                                                                    |
| ------------------------------------------------------------- | ---------------------------------------------------------------------------------------------- |
| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | Returns true if the property you pass in is locked by this material. Otherwise, returns false. |

### Remarks

If a property is locked by the material, any Material Variant inheriting from this Material will be unable to change the value of the property. If a children material overrides a locked value, the override is stored in the children but won't have any effect until the property is unlocked.

Note that this method is Editor-only.
