### Remarks

[LightingSettings.LightmapPackingMethod.XAtlas](/engine/6000.6/script-reference/unityengine/lightingsettings/lightmappackingmethod/xatlas.md) is slightly slower than [LightingSettings.LightmapPackingMethod.Unity](/engine/6000.6/script-reference/unityengine/lightingsettings/lightmappackingmethod/unity.md), but produces better results.

Use [LightingSettings.LightmapPackingMethod.Unity](/engine/6000.6/script-reference/unityengine/lightingsettings/lightmappackingmethod/unity.md) for compatability with older versions of Unity.
