Earlier this week I downloaded the 3rd party route from Otto Wipfel's site. It's RW_Tennessee Pass 2. Those files are no problem with the program of Railworks but one thing I am not sure if the Assets folder are setup correctly. Because I ran through this route to see why this route did not show up in the menu in Train Simulator 2016. Anyway here is what I have the setup for Assets in my main hard drive below:
Steam > SteamApps > common > RailWorks > Assets > 3DTrains > ScaleRail > RailNetwork > 4 subfolders with SR_OTTO-DK-GRAY; SR_OTTO-GRAY; SR_OTTO-PINK and Trackrules.
RW_Tools program couldn't find 3DTRAINS\SceneryPacks.
Now you see what is about missing files?
I am not quite sure if I did this correctly?
