> Whether to flip the way triangles face in the geometries reference by ray tracing instances.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine.Rendering](/engine/6000.5/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public bool frontTriangleCounterClockwise { readonly get; set; }
```

### Remarks

By default, in object space in a left-handed coordinate system, a triangle is front facing if its vertices appear clockwise from the ray origin, and it is back facing if its vertices appear counter-clockwise from the ray origin.
