I have seen that in Lay Track Curves, there is an option to add parallel tracks when building the first track. However, I didn't use that in this case. Now I have a track and want to create a new one next to it. Does anyone know how to achieve this?
Simples, press Shift before clicking on the track node and it should pop up with a tool to set the offset that you want then it's an easy game of follow the rail .
