one-way sky?

hey, i am trying to make a map where there is a large observatory chamber, and the terrain is a func_train and pushing a button will make the terrain move from the void, up onto the floor of the chamber. i have all of that worked out fine, but i wanted to make the skybox one way, so that if u were in the actual level, u would see sky but if u were in the observatory area u could see THROUGH the sky and see what is going on.

I know this idea sounds wierd, but please work with me.

PS: its a complex idea too, but i dont know how to load screenshots into snarkpit so i can show pics, any help there would be good too

I think putting a "skybox" texture on the level side of a brush and a "no draw" texture on the observatory side might work, but I'm no expert so don't take my word for it :smile:

Upload the screenshots to www.imageshack.us. Instructions are on the site. :smile:

Displacement maps don't actually move, so if you were planning to make
your terrain that way, well, it won't work. And brush based
terrain will likely look hideous.

Yeah, I found out the hard way that displacement maps can't do ANYTHING. You can't tie them to an entity! So yeah, gl with that.

Maybe I'm not understanding, are you wanting people to look down at the
rest of the map and see through the back of the skybox brushes?

If that is the case couldn't you just put a clear brush on the back
side of the brush? Maybe tools/toolsinvisible, or just a glass texture?

As Sam37 said, sky texture on the inside and nodraw on the observatory side. Good luck.

Yeah like this:

Observatory - No draw texture -----> | <--- Main Area - Skybox texture

Wall ^

GD luck :smile:
