Halp!
I have discovered since I suck at 3ds I am incapable of making a tunnel. The area I need tunneled and enclosed in rock is shown tunneled in this picture. Help can be repayed in the form of extensive track rates or something else.
Textures don't have to match well (recent blasting means fresh rock looks different than weathered rock), the tunnel shape can be whatever is easiest (doesn't have to be a circle), and I'm kind of hitting a wall right now because of this stupid tunnel. The exterior rock wall needs to follow the outside of the track that the green train is on (note the falling rocks tunnel that is there to make people feel better despite that a boulder would murder it lolz)
As far as the ride goes I'm on the detailing stage. All wide supports are done except for the helix and what is shown in the screenshot. I'm adding diagonal bracing to the existing finished wide supports and doing the diagonal squiggle reinforcing beam things (don't ever do these they will make you insane).
Anyways here is a picture of what I need done.
