# bounceCombine

> Determines how the bounciness is combined.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.6/script-reference/unityengine.md)
* **Assembly:** UnityEngine.PhysicsModule

```csharp
public PhysicsMaterialCombine bounceCombine { get; set; }
```

### Remarks

Traditionally bounciness properties are dependent on the combination of the two materials in contact. This is however impractical in a game. Instead you can use the combine mode to tune how the bounciness values of two materials are combined.
