ok, i was having a look on snark, and i found the tutorial on how to make the tunnel.  I had a quick go, and all was fine until it came to paint alpha, and also invert alpha.  Nothing happened when i used these.
im not sure what is supposed to happen with invert apha, but when i use paint alpha, my textures arent painted on, as i guess they are supposed to.
any ideas?
