| [GetDelegate](/engine/6000.0/script-reference/unityengine/experimental/globalillumination/lightmapping/getdelegate.md)     | Get the currently set conversion delegate.                                                                                                                              |
| [ResetDelegate](/engine/6000.0/script-reference/unityengine/experimental/globalillumination/lightmapping/resetdelegate.md) | Resets the light conversion delegate to Unity's default conversion function.                                                                                            |
| [SetDelegate](/engine/6000.0/script-reference/unityengine/experimental/globalillumination/lightmapping/setdelegate.md)     | Set a delegate that converts a list of lights to a list of LightDataGI structures that are passed to the baking backends. Must be reset by calling ResetDelegate again. |
