Why is my skybox not working?

[ChrisVR]

I have 6 textures named with _N _S etc, they are JPG files of 256x256 resolution.

I have made a GLDEFS entry in my pk3.

 

Skybox Sky1
{
  SISKY6_N
  SISKY6_E
  SISKY6_S
  SISKY6_W
  SISKY6_T
  SISKY6_B
}

 

Can't figure out what am I doing wrong...

I have followed the suggestion from Aquila - I created a small sector at the side and lowered the skybox. Works both in the builder and the game. Thanks!

 

Congratulations, you've just utilized one of the oldest special effects in the engine!  Sometimes what works well enough in 1993 still works well today!

The skybox is all good but...you need to define the sky in MAPINFO too.

map MAP01 "xxxx"

{

sky1 = "Sky1"

}

Then you need to put the F_SKY flat as ceiling. That will show the sky properly

[ChrisVR]

Thanks man! It partially works.

Applied to ceiling is ok, but when I apply it to the wall, it does not work. Anyway to fix it?

[leodoom85]

um...two ways to solve.

You use the sky hack technique or use the Line_Horizon action to the walls if you're using the UDMF format. You don't need to put that flat to the wall.

We're almost there!

Is it possible to prevent my 'building' from expanding into infinite horizon?

[leodoom85]

Maybe doing another sector around that building and lower the floor so that it doesn't look like that

I made it look like this with the "9 line horizon" but it's still the same in-game..

So, you have the six image for the skybox.

Next you have to set up MAPINFO and GLDEFS.

You can also create a small sector at the edge with a sky textured ceiling and lower it to the floor and it will render the sky, but not the same way that Line_Horizon does, without the edge.

Look at the outside area of Doom 2 MAP01 for an example of how to do the sky trick they are talking about.
