* **Assembly:** UnityEngine.CoreModule

## QuantisedVectorHash(Vector3, Hash128)

```csharp
public static void QuantisedVectorHash(ref Vector3 value, ref Hash128 hash)
```

### Parameters

**** (\[Vector3]\(/engine/6000.7/script-reference/unityengine/vector3)): The computed hash.**** (Hash128): The Vector3 to hash.

### Remarks

The Vector3 is quantized before the hashing with a step of 0.0005.
