I've downloaded this airport scenery from the Avsim / Greece site but have noticed that the taxiway edge markings / centrelines / taxiway signs do not appear at all. Everything else is fine - has anyone else seen this as it is supposed to be one of the features?

Just checked and you are correct..however :-) Change your 'Scenery complexity' to Very Dense and the taxiway markings become visible, anything less and they are not there either by day or night.Rgds

Thanks for that, Vulcan. All the detail shows up now!:-)
