### Remarks

Enabling this setting can mitigate artifacts caused by block texture compression but may reduce packing efficiency.

This setting only has an effect when using [LightingSettings.LightmapPackingMethod.XAtlas](/engine/6000.6/script-reference/unityengine/lightingsettings/lightmappackingmethod/xatlas.md).
