Tunnel Colliders and Looping Meshes

[Petusarian]

Here is an example of two splines/tunnels connecting, you can see how the tunnels intersect into one another: 
   

Here's when I use the space before and after setting, as you can see it creates spaces between all tunnel walls which isn't needed:
   

I created a script that detects if the walls are intersecting with another spline and it automatically removes them, leaving gaps that I can easily fill in so that's not a problem:
   


I made this script in 10 minutes and it does require some manual setup to work but it does a decent job so it would be very nice if the generator itself had a similar option to skip placing the mesh if another spline is in the way.
