+Reducing LightmapGI artifacts
+-----------------------------
+
+If you notice LightmapGI nodes popping in and out of existence as the camera
+moves, this is most likely because the engine is rendering too many LightmapGI
+instances at once. Godot is limited to rendering 8 LightmapGI nodes at once,
+which means up to 8 instances can be in the camera view before some of them will
+start flickering.
