I was going to post this message and decided to try adding a roadway again, and by accident made an interesting discovery. In trying to create roads in Ground 2k, I had no trouble in compiling and displaying a one-leg road in FS9. But when I tried to compile a road of more than one leg using the texture asphalt/2lane/undivided median - #1243, I got the following error message in my log, and the road did not display in FS:

Hi Nigel.1243 is a bridge vector and needs only 2 points... otherwise the bridge won't display correctly. Ground2K4 will show an error if more than 2 points are used for bridges.The FS9 terrain.cfg file shows the attributes of the numbers.Dick

Thx Dick, maybe I will try some bridges now.Nigel
