Hi,I'm trying to make an MKE scenery, but don't know how to create tarmacs, taxiways, and runways in gMax. Is there a way to do this using the default taxiway textures? And how to you add lighting to the taxiways and runways so that it comes on during foggy weather and at night only? Thanks for any help!

GMax does not allow you to make aprons, taxiways and runways directly. This is because GMAx is mainly an object designer. I would advice you to use a program like FSSC (http://www.avsim.com/fssc) for these parts of the scenery.If you really want to make it with GMax, it is possible. You need to draw the polygons then, map the texture you want. After you have made the BGL then you need to tweak the source a bit to let the polygons display correct (there are some tips about this on my site, link is in my signature).
