Design Question

Hi AllI am really confused about designing scenery and implementing texturesI have recently released my first scenery as freeware, see pic...I used what I suspect is the time honoured way, creating polygons and assigning textures and was surprised by the outcome. However, it strikes as extremely exhaustive to go to those efforts, when they could be on one or two bitmap's.I guess I want more control over my textures, for Taxiways, Runways, White lines not yellow, etc...I'd be grateful for any of your viewsregardsDave
