Hey everybody! For those of you who have used Immersive Railroading, you know that the trains are lifesize, which is awesome! However, the Minecraft terrain doesn't seem to fit the demands of realistic trains. Trains require more flat surfaces or surfaces that don't vary more than a few blocks in height every 50 or 70 blocks.
So my question is this - without just using a superflat world, what would you recommend or what have you used to modify world gen to make Immersive Railroading more usable? If you haven't used mods, how have you coped with the volatile height changes in Minecraft when trying to run your rail lines?
