LightmapProbe

Description

LightmapProbe represents the position of a single manually placed probe for dynamic object lighting with LightmapGI. Lightmap probes affect the lighting of GeometryInstance3D-derived nodes that have their GeometryInstance3D.gi_mode set to GeometryInstance3D.GI_MODE_DYNAMIC. Typically, LightmapGI probes are placed automatically by setting LightmapGI.generate_probes_subdiv to a value other than LightmapGI.GENERATE_PROBES_DISABLED. By creating LightmapProbe nodes before baking lightmaps, you can add more probes in specific areas for greater detail, or disable automatic generation and rely only on manually placed probes instead. Note: LightmapProbe nodes that are placed after baking lightmaps are ignored by dynamic objects. You must bake lightmaps again after creating or modifying LightmapProbes for the probes to be effective.
