		Prerendered indirect light map for a scene.
	</brief_description>
	<description>
		Baked lightmaps are an alternative workflow for adding indirect (or baked) lighting to a scene. Unlike the [GIProbe] approach, baked lightmaps work fine on low-end PCs and mobile devices as they consume almost no resources in run-time.

			Grid subdivision size for lightmapper calculation. Default value of [code]0.25[/code] will work for most cases. Increase for better lighting on small details or if your scene is very large.

		<member name="bake_hdr" type="bool" setter="set_hdr" getter="is_hdr">
			If [code]true[/code], lightmap can capture light values greater than [code]1.0[/code]. Turning this off will result in a smaller lightmap. Default value:[code]false[/code].
