First, I hope I'm doing ok by creating a second topic about a different issue for me rather than lumping them together. Now that I've gotten a somewhat better handle on track laying, I decided that I really need to work on terrain first. So, I did as much reading and researching as I could and found several useful topics on here, as well as the Searchlight Simulations .pdf tutorial. But nothing is working. I did find the topic here discussing that routes sometimes change their starting coordinates, and in my current route I have verified that the coordinates are correct both as displayed in-game, and in the .xml file. The only part where I might have gone wrong that I can think of, is I had to manually create the SRTM folder inside the DEM directory. The other issue I might have, is the 1/3 arc second data after running it through BILxSRTM, is not a single file, it's named N33W084T17.hgt, N33W084T18.hgt, N33W084T19.hgt and so on instead of just N33W084.hgt as the lower resolution data is.
Does anyone have any advice on what else I can check or do to make this work?
Thanks again.
