The sceneries that required updates were only those that have their own Dynamic Lights, and we update them already, like KORD V2 or LFSB.
KLAX doesn't use any Dynamic Lights so, it doesn't need any update so, I'm not sure which DL you are referring to. Are you using add-on DL for KLAX by Inibuilds ? If yes, then it's likely the'll have to update their effects.
