Quote - "In the beginning of the tutorial you mentioned how to create roads/patchs in VUE."

Yes, you're right. I had intentions of doing it at a later time but I ended up never really doing it, for lack of time. Anyway, the workflow is not very different from GeoControl. You can follow these general steps:

1- Create a standard terrain in the resolution that you find more adequate for the camera distance (if it's close, use 2048 or 4096 (if your system can handle it), if it's distant you can use 512 or 1024).

2- Edit the terrain with Vue terrain editor. Tick the checkbox "airbrush style" and choose a brush (button to the right of the checkbox) that's adequate to the kind of road you want (more or less rugged).

3- Paint your terrain and road in the terrain editor. It's not as nice as GeoControl but, with time and perseverance, it can look good too.

4- After it's done, click on the button "Export terrain", in the terrain editor (lower right corner). Export it as bitmap. Warning: I think this button doesn't exist in all versions of Vue. Infinite has it, but for example Pioneer doesn't have it.

5- You can open this bitmap in Photoshop (or other 2D tool) and from here the steps are the same as in my tutorial (paint the distribution maps, etc).
