Tunnels

[coasterlover420]

Has anyone come up with a simple easy way to create underground tunnels for NL, because when you just send the track under, the grass gets in the way.

 

Any ideas are appreciated!

The easiest way to export the terrain to 3ds, and then combine that with an auto-tunnel and create your own.

Could you explain, please...!

1) Create the terrain, for the time being ignoring where the tunnels are going to go.

2) Using the old terraformer, export the terrain as a 3ds file

3) Use the tunnelmaker to create some tunnels for the track.

4) With a modelling program (I use anim8or for this), import the terrain & tunnel files into the same scene, theorectically they shouild line up.

5) Move some of the vertexes to sit just inside the tunnel walls to help avoid gaps, and remove the faces blocking the tunnel entrances.

6) Remove all the excess terrain (anything that isn't the tunnel, but leave a little spare - i usally leave like 3 or 4 squares outside where the tunnel is to make sure) and outer tunnel walls that wont be seen to help keep polycount down.

7) Texture however you want, then export

8) Line up the 3ds terrain with the NL terrain, then, in the terraformer, use the cut track path tool to clear the terrain around the tunnel (Or do it all by hand), then just check nothing is poking through.

 

VOILA! I think that's everything, it works for me.

Thanks, but how do you use anim8or? I can't get it to show both 3ds files

[BorisTF]

If you've imported both 3ds files into anim8or, copy paste one into the other, they should line up perfectly.

Thanks, but I can't get the points to move. What command or option makes them move?
