Jerker, hello!
This was the initial situation I was speaking of:
However, I had re-exported the route into Trainz, and the sky was there as well as the black land. Unfortunately I did not take a picture of it. I had opened the mini-map and Trainz had closed unresponsive. I reopened Trainz, and this is what came up:
I closed the route out of surveyor and returned to the menu. I went back to open the route and this came up:
I did the same thing again, and the layout returned to pure pitch-blackness:
And here's a freelance layout I've started, all of the other layouts work just fine as well.
I don't think it's entirely Trainz' fault, however it probably isn't TranzDEM's either. As to WHY? I am uncertain. Perhaps something to do with the export process may explain it. Granted, the DEM I've been working on covers a large amount of geography, covering 3 small Balkan countries; the entirety of Albania, south Montenegro(around Podgorica), west Macedonia(around Skopje), soutwest-central Kosovo(Pristina), and Northern Greece(Larisa and Ioannina). All are areas near the Albanian border and that of their respective countries. Perhaps I should re-export, use the 'lasso' tool, and divide the DEM into smaller regions?
This is the DEM; there are 4 DEMs at N39, 3 at N40 and N41, and then 4 more DEMs at N42; so 14 DEMs in total; 11 raster maps that make up the entire route area.
As you can see, there are numerous lines throughout the DEM, connecting some of the main cities I spoke of (e.g. Podgorica, Skopje, Larisa, Pristina, etc.) as well as Vlore, Durres, Tirana, Ioaninna, Elbasan, etc.
Yes, this is being done on a Mac via Parallels. I have created a DEM before this way, so I doubt it has to do with the fact I'm working on a Mac via Parallels.
If anyone has ever encountered this problem before, or perhaps has some kind of solution or idea towards a solution, it would be greatly appreciated! I'd like to keep the current setup I have, with the entire network on the current geographical area; however if push comes to shove, I am willing to downsize the layout.
