Update:
For my ENLI photoscenery, I set the runway width to zero. This is no problem here, as the (ex NATO) runway now is closed, and only used for micro planes and airshows now and then.
Then I solved the wheel smoke thingie. I made a poly covering the whole runway, in 25 100 x 100m sections (= 2500 x 100 meters). Done that way, it will form to the curved earth. As expected, the gmax Attach Tool failed to make a hardened surface. Could be because I forgot to set a GUID first?
Anyway...
The gem called Model Converter X did that for me, just by pushing a few buttons, and I reexported my poly from MCX with the same name.
Then I made a concrete texture with an alpha channel, for hiding my poly. I did something wrong with the gmax material settings (too easy to do!), so it showed in FSX. Again, MCX solved things for me. I opened the material there, and just pushed the "Set Default Transparent" button. Viola!
Now, how to make the taxiways invisible? I just made them Path instead of Taxi. How to hide the WW2 runway crossing the NATO runway? The same, made a 70m taxi path there too (That runway is not in the afcad, only in the photoscenery). Invisible taxipaths gives no wheel smoke, hence no need to make hardened surfaces.
Result: A very, very realistic ENLI.
So the good news here for high-rez photos, is one only need to make the hardened surfaces for the aprons...if the apron lines have a good enough sharpness. For photoscenerys where AI traffic is needed, I leave the default runway "as is", and tune the runway "shoulder" coulour to the runway colour. Mostly, I get a very nice blend this way.
Cheers,
