The height map in the first version of Bagen was only 1/2 as high as it should be due to a bug in the importer. The map is also wider than it should be. This causes the hillsides to intrude on the road. If you compare the insides of the first, last and top left turns you can see the difference this makes. I have been able to correct this with some gimp tricks. So please give this new version a try and, if you have the time to compare the 2 versions your feedback would be appreciated.
