# IsValid

> Whether the reference points to blob data.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/7000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AnimationModule

```csharp
public readonly bool IsValid { get; }
```

### Remarks

The value is `false` for a default reference, for a reference that you disposed, and for a reference that [BlobObject.AcquireReference](/engine/7000.0/script-reference/unityengine/blobobject/acquirereference.md) returned because the object was empty or stored another type or version of the blob. Destroying the object after you acquired the reference doesn't make it invalid.
