HaloMods "Classic" Read-only Archive

Well, I was going to play with BG and try to make a real fun mod that sort of looked like an alien land, night, all that stuff. I have already been playing with Spark Edit, and know some about it. Also I downloaded HMT3, and well still looking into that (any good links about useing it would be helpful)

But back to the point, in this mod I wanted 1 or 2 tunnels underground, so like you could get inside near (not too near) one base and come out near the other. So I was thinking I was going to have to do something sorta like these mods with platforms, but underground, but HOW? I know you will probally say Gmax, but can you elaborate or link? Even if I can't do the underground stuff I would still like a nice platform

Thanks.

Don't hope to do underground until the hek is out. Anything out of the map does not work.

OK then, just normal platforms

EDIT - I found a stickey that sort of looks like what I am looking for, but all of the links are dead. And I don't see why in the heck this was moved I want to model a platform...
