		<method name="get_flag" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="flag" type="int" enum="GeometryInstance.Flags" />
			<description>
				Returns the [enum GeometryInstance.Flags] that have been set for this object.
			</description>

		<method name="set_custom_aabb">
			<return type="void" />
			<argument index="0" name="aabb" type="AABB" />
			<description>
				Overrides the bounding box of this node with a custom one. To remove it, set an [AABB] with all fields set to zero.

			<return type="void" />
			<argument index="0" name="flag" type="int" enum="GeometryInstance.Flags" />
			<argument index="1" name="value" type="bool" />
			<description>

	<members>
		<member name="cast_shadow" type="int" setter="set_cast_shadows_setting" getter="get_cast_shadows_setting" enum="GeometryInstance.ShadowCastingSetting" default="1">
			The selected shadow casting flag. See [enum ShadowCastingSetting] for possible values.
		</member>
		<member name="extra_cull_margin" type="float" setter="set_extra_cull_margin" getter="get_extra_cull_margin" default="0.0">
			The extra distance added to the GeometryInstance's bounding box ([AABB]) to increase its cull box.
		</member>
		<member name="generate_lightmap" type="bool" setter="set_generate_lightmap" getter="get_generate_lightmap" default="true">
			When disabled, the mesh will be taken into account when computing indirect lighting, but the resulting lightmap will not be saved. Useful for emissive only materials or shadow casters.
		</member>
		<member name="lightmap_scale" type="int" setter="set_lightmap_scale" getter="get_lightmap_scale" enum="GeometryInstance.LightmapScale" default="0">
			Scale factor for the generated baked lightmap. Useful for adding detail to certain mesh instances.
		</member>
		<member name="material_overlay" type="Material" setter="set_material_overlay" getter="get_material_overlay">
			The material overlay for the whole geometry.
			If a material is assigned to this property, it will be rendered on top of any other active material for all the surfaces.
		</member>
		<member name="material_override" type="Material" setter="set_material_override" getter="get_material_override">
			The material override for the whole geometry.
			If a material is assigned to this property, it will be used instead of any material set in any material slot of the mesh.
		</member>
		<member name="use_in_baked_light" type="bool" setter="set_flag" getter="get_flag" default="false">
			If [code]true[/code], this GeometryInstance will be used when baking lights using a [GIProbe] or [BakedLightmap].
		</member>

	<constants>
		<constant name="LIGHTMAP_SCALE_1X" value="0" enum="LightmapScale">
			The generated lightmap texture will have the original size.
		</constant>
		<constant name="LIGHTMAP_SCALE_2X" value="1" enum="LightmapScale">
			The generated lightmap texture will be twice as large, on each axis.
		</constant>
		<constant name="LIGHTMAP_SCALE_4X" value="2" enum="LightmapScale">
			The generated lightmap texture will be 4 times as large, on each axis.
		</constant>
		<constant name="LIGHTMAP_SCALE_8X" value="3" enum="LightmapScale">
			The generated lightmap texture will be 8 times as large, on each axis.
		</constant>
		<constant name="LIGHTMAP_SCALE_MAX" value="4" enum="LightmapScale">
		</constant>
		<constant name="SHADOW_CASTING_SETTING_OFF" value="0" enum="ShadowCastingSetting">
			Will not cast any shadows.
		</constant>
		<constant name="SHADOW_CASTING_SETTING_ON" value="1" enum="ShadowCastingSetting">
			Will cast shadows from all visible faces in the GeometryInstance.
			Will take culling into account, so faces not being rendered will not be taken into account when shadow casting.
		</constant>
		<constant name="SHADOW_CASTING_SETTING_DOUBLE_SIDED" value="2" enum="ShadowCastingSetting">
			Will cast shadows from all visible faces in the GeometryInstance.
			Will not take culling into account, so all faces will be taken into account when shadow casting.
		</constant>
		<constant name="SHADOW_CASTING_SETTING_SHADOWS_ONLY" value="3" enum="ShadowCastingSetting">
			Will only show the shadows casted from this object.
			In other words, the actual mesh will not be visible, only the shadows casted from the mesh will be.
		</constant>
		<constant name="FLAG_USE_BAKED_LIGHT" value="0" enum="Flags">
			Will allow the GeometryInstance to be used when baking lights using a [GIProbe] or [BakedLightmap].
		</constant>
		<constant name="FLAG_DRAW_NEXT_FRAME_IF_VISIBLE" value="1" enum="Flags">
			Unused in this class, exposed for consistency with [enum VisualServer.InstanceFlags].
		</constant>
		<constant name="FLAG_MAX" value="2" enum="Flags">
			Represents the size of the [enum Flags] enum.
		</constant>
