Sky texture question Created 11 years ago2013-02-10 03:03:57 UTC by zeeba-G

I've seen it done where a room's walls are textured with the sky texture and you cannot see into the surrounding rooms. When I try this you can see through the sky textured walls into the other rooms. Does anyone know how to do this?

I don't think you saw what you thought you saw, since a skybrush itself will always render invisible afaik.

What i think you saw is someone made an additional texture from the environment texture, at least that would be my first guess

Do you remember the map?

Yea I even checked, its a map for counterstrike 1.6, blahhh by Nipper. Maybe it just happens that way in cs 1.6... I tried in condition zero.

I also assumed that I was mistaken until I checked.

Edit: Oh maybe if I just layer the room with another brush all around it.

Double Edit: Nothing seems to be working. Maybe I can decompile the map to find out what was done.

Through sky brushses, you can see whatever VIS can see. Clever use of hint and null brushes + special geometry around the sky brush itself could fix your problem.

Could you do an example soup? that could be pretty damn useful, especially hiding "see-through" areas of skybox, with a concave layout, where there are no walls to hide the overlap!

meanwilst i'm gonna try out that nipper map and see what zeeba is talking about, i think i already have it..

edit
I see you were right zeeba! I will now munch on my own words =)

I decompiled the map but couldn't see anything unusual. One part was two layers of sky textured brush and then a third layer brush with a wall texture but this may have been because of the decompile as it wasn't the same on the other walls.

I've never used hint brushes, hmm.

maybe the cooridor is just far enough away so vis isn't rendering it, in other words, no special trickery needed here; In other cases--such as i described above--, this method will not work ='(

So i guess it depends on what you're trying to do exaclty

In one of the spawns it does it to areas directly surrounding it. I actually pm'ed Nipper the guy who mapped it on gamebanana. We'll see if he responds.

Link to map i'll paw around with it trying SSSSOUPINATOR's! method if you want.

Just use multi layers or a thick skybox.

Awesome Stojkens! I wish i knew that like 6 years ago! =)

Sure is
Well, know how they say, you learn something new each day.

Strojke as soon as I link two of the areas with a hallway you can then see through the sky into the other areas. I think it only worked for you because the areas weren't accessible.

Well, truth is it is just like soup says, but a thick skybox should block off VIS:

I didnt try multi layer, you will need to experiment.

Edit: Nevermind, I thought you were on about something else.

Maybe it is just that it was in cs 1.6. I'll mess around some more with it soon.

I've always wondered this. You can see this in some of the original Half Life maps.

I wish I had screenshots of it at hand, but I can't find them at the BMS site (even if I know I've seen them there) and I don't remember what the chapter is called (or even where it is in the game), but it's where you come out of an underground parking lot just to see a gargantua fighting some soldiers, a plane flying overhead dropping bombs on them and a tank with a handful of grunts around it at the far end of the road.

When you get into the building closest to the road (where you find a Barney in the locker room) there are small windows through which you can only see the skybox from the inside, and a black brush from the outside. Yet they are the same windows and there is no map change in between the areas.

This, right:

Outside the building:Inside the building:Map is c2a5e.

Inspection shows that its composed out of 3 parts:They are encased into the Func_wall entity thats the window bar texture.
The two other parts are solids.

The front solid has a SKY texture on it, while the other side is BLACK. The second solid has BLACK on both sides.

This way VIS is blocked, but i tried this before and all i got was a black box behind my sky...

Just tested it, it works:
BSP File
RMF File
[Halflife.wad | cs_dust.wad]

YES! That place exactly. Thanks Atom, glad my description was clear enough
