		Computes and stores baked lightmaps for fast global illumination.
	</brief_description>
	<description>
		The [LightmapGI] node is used to compute and store baked lightmaps. Lightmaps are used to provide high-quality indirect lighting with very little light leaking. [LightmapGI] can also provide rough reflections using spherical harmonics if [member directional] is enabled. Dynamic objects can receive indirect lighting thanks to [i]light probes[/i], which can be automatically placed by setting [member generate_probes_subdiv]. Additional lightmap probes can also be added by creating [LightmapProbe] nodes. The downside is that lightmaps are fully static and cannot be baked in an exported project. Baking a [LightmapGI] node is also slower compared to [VoxelGI].
		[b]Procedural generation:[/b] Lightmap baking functionality is only available in the editor. This means [LightmapGI] is not suited to procedurally generated or user-built levels. For procedurally generated or user-built levels, use [VoxelGI] or SDFGI instead (see [member Environment.sdfgi_enabled]).
		[b]Performance:[/b] [LightmapGI] provides the best possible run-time performance for global illumination. It is suitable for low-end hardware including integrated graphics and mobile devices.
