I was wondering how one would go about creating custom scenary for use in a map. I had an idea, but it would require a large piece of scenary to be part of the map as it would not work otherwise. I'm making a racetrack where when you get to the end, you push a button and it deletes the track, or at lease lowers the track into a kill zone. Any help would be great.

As far as I know that is not possible, OR it hasn't been done yet so its not going to be easy.

You can make the scenery but it would have no collision thus you would walk through it. I have made quite a few custom weapons and equipment but not scenery yet for exactly this reason.

My currently broken Bubble Shield has some interesting characteristics though. The model was setup to be similar to the ball (or Skull) render_model, so the model has the same nodes (frames) and markers. Then I told the model tag to use the balls (Skulls) collision and physics_model. So I call it broken because it does not deflect munitions but it does bounce and roll if I drop it from higher up or combine it with my Gravity Lift. But still, no collision...so then I was like screw this Skull so I went with the Plasma Grenade model which is a perfect sphere with an extra square sitting on it to represent those yellow symbols. If I could somehow upscale the size of an existing collision tag then I think it could work. Unfortunately that is as far as I've gotten because the map would fail to appear in the map list if I used the Plasma Grenade.

A couple of years ago Jahrain mentioned a Collision model upgrade tool, but I don't think it was finished or released and without that most scenery has little use.

I started a tutorial that explains some of this further and lists many helpful tools:

As to moving objects; the only thing I can get to move (or appear to be moving) in-game is the treadmill > symbol but that NOT is going to give you a bridge that lowers or disappears.

Yeah, I forgot about most of that stuff, I had just tried doing stuff with halo CE, and I forgot the halo 2 sapien didn't have the scripts function, bungie probly removed it before release.
