Rct 3 Soaked - How do you do tunnels?

[Jak]

I was just wondering how do you do tunnels on rct 3 soaked?

i think their is a tutorial for it but if not you make a vertical rise or lower in the terrain (no slope) and run the track through it. If it wont let you it probably means that you need to raise or lower it more. the terrain will be highlited if needed. if you want you can out cave entrances and stuff on it from the scenary selection.

Yeah you need to create a fully flat slope by using the single land drag tool. Then you just need to create a face big enough for it to go through.
