Terrain Tunnel Help

Alright so I've started at relatively small project. But I really want to add a 3ds tunnel that goes through terrain. So i am wondered if anyone would be will to make a tunnel for, or maybe even the name of a person that is good at making tunnels.

Thanks

I'm not sure if someone will make one for you. But there's a good chance that someone will tell you how to make one. And you can make them go though terrain, but it would look really bad, you would need to lower the ground were the tunnel is.

Yes I know all of the basics. Its just that I don't have enough skills with 3d programs to make a semi-realistic looking terrain around the tunnel, or even have the tunnel follow the track perfectly. That's where i need the help.

I will make one for you.

Almost everyone that makes tunnels makes them on flat ground. Then all you have to do is make a flat 3d, and put the grass texture on it with the right amount of repeats. To make it follow the track, get the Construction kit, and export it as 3ds.
