# motionVectorStencilMask

> Bitmask of the stencil bits that Temporal Pixel Synthesis tests when excluding pixels from temporal reuse.

## Definition

* **Type:** Field
* **Namespace:** [UnityEngine.XR](/engine/7000.0/script-reference/unityengine/xr.md)
* **Assembly:** UnityEngine.XRModule

```csharp
public int motionVectorStencilMask
```

### Remarks

Stencil buffers are 8 bit, so this is expected to fit in the range 0-255. Only meaningful when [XRDisplaySubsystem.XRRenderPass.isTemporalPixelSynthesisActive](/engine/7000.0/script-reference/unityengine/xr/xrdisplaysubsystem/xrrenderpass/istemporalpixelsynthesisactive.md) is `true`.
