# strictVertexDataChecks

> Enables strict checks on imported vertex data.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.3/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public bool strictVertexDataChecks { get; set; }
```

### Remarks

When enabled, checks are performed on the imported vertex data. When invalid data is found, it is discarded and a warning message is logged in the console. This may result in missing vertex data but ensures that results are consistent and can prevent crashes during imports. Checks involve a performance penalty and are disabled by default.
