The spacing and positioning issue still persists with the default AI taxiway lights. Some are closer, some are distant and some even out of the line (both centreline & edge lights). There isn’t a proper tool in the sdk yet to manually adjust the position and spacing of the default taxiway lights.
Sadly, very few 3rd party devs are presently doing custom taxiway lighting, I don’t know why; but rest all addons still comes with the default msfs sdk taxiway lights.
SDK/ Dev team, Please do something with the default msfs taxiway lights so that its possible to individually adjust placement of lights and manually place the taxiway centreline and edge lights with proper spacing. Its a very basic necessity of an airport and an immersion killer at night for an otherwise beautifully crafted airport.
