Thanks for the responses. Since I first tried these out I have added GE, UT and a better mesh. The outcome this time seems to be that only the grid-like road system is lying on top of the more irregular mesh and without the green furrow texture. I'll have to play with this a little as I also don't exactly know where the new textures should appear geographically, other than the appearance of the roads. I managed to install a second FS9 but have not yet figured out how to create an independent start icon for it, although I know there are posts on that I have not yet looked at. Once I do that I'll use it to see how these files look and take it from there.
