 		[b]Note:[/b] Due to how lightmaps work, most properties only have a visible effect once lightmaps are baked again.
 		[b]Note:[/b] Lightmap baking on [CSGShape3D]s and [PrimitiveMesh]es is not supported, as these cannot store UV2 data required for baking.
 		[b]Note:[/b] If no custom lightmappers are installed, [LightmapGI] can only be baked from devices that support the Forward+ or Mobile rendering backends.
