The "EmMesh" parameter of the aircraft lighting config doesn't make any sense to me. I input the name of a node that has a material with emission, but in user lights window it always says "Emissive mesh not found". I think I'm missing a step somewhere, but that step is not documented. Defining the emission in the ModelBehaviors works fine, but in the default aircraft there is no mention of the exterior lights emission in the ModelBehaviors.
