animated skybox

Im trying to create a level based on a moving train.

Im not sure whether the best way to do this is make the train move (may cause physics problems)

I have decided to try and animate a skybox, but ive absolutely no idea how to do this, i cant make Displacemtn surfaces move. Does anyone know a way to make a convincing moving skybox?

Thanks in advance for any help.

I thought you could tie displacements to entities (like a train).

But you sound like your on the right "track" (pun intended), by making
either a repeating train terrain, or a func_rotating (in the sky box
perhapse).

You cant tie displacements to an entity unfortunately, hence you cant make them move. Youll just have to try and make your terrain out of regular brushes I'm afraid, and tie it to a train or similar.

hmmmm maybe the sky camera ent can rotate, to give the illusion that
the world is rotating. By chance does this have anything to do with the
assult map for UT2004?! If so just look at how they did it in the
editor, maybe it will give you an idea!

I dont have UT2k4 :sad: But yeah, i do love that level, and ive seen how its done.

The boulders/wheels/mountains move around.

Ill try parenting the sky camera and rotating it, see whta happens.

The problem is the train has too be 15 carriages long, so its not as simple to animate the mountains like in the assault map. Its for a single player mod i anyone cares. Revolutionmod.cjb.net if you want to look. But the first chapter has the player airlifted onto a speeding train, :razz: so the most important part of the entire level will be the skybox.

Another thing i was going to try, havent got around to it yet. Is using triangle terrain like in HL1, then making that a func rotating, migh stump performence a little though.

You can make things move in the skybox by tying them to entities; it should not be hard to make scenery which scrolls by and returns to the beginning again, conveyor-belt style.

Its getting there, im using triabgle scenery (used in HL1 i beleive) and making them func_tracktrains, but they keep facing the wrong way so im fiddling with the settings, after that it shouldnt be hard to animate some boulders and whatnot. Cheers Guys, oh and im glad i found you guys again :razz:
