You need to download a program called "Slade 3" at https://slade.mancubus.net/

 

In slade create a Wad Archive and add an SS_START and SS_END Marker

 

Then you need to copy it and paste your Doom 2 sky into your wad's inbetween the SS_START and SS_END markers, Name it RSKY1 if it is a Doom 2 wad, SKY1 for a Ultimate Doom megawad.

 

Then you open up your editor, add your custom sky wad, and your IWAD you are using.

 

Set your ceiling or floor to F_SKY1.

 

Test it in your source port of choice or DOS and then you should have the sky!

That's for how to set a new sky. If you want the sky to look like the one in doom 2 e1m1:

Make a sector for where you want the sky horizon to be. Then make that sector's ceiling F_SKY1 and drag that ceiling down -- it will follow with rendering the sky, recreating Doom 2's horizon. No need for Slade or SS markers, etc.

all you need to do download a sky texture and put it in then rename it to RKSY1 (or SKY1 for doom 1 and plutiona) but if want to change the sky for a map that uses the the second sky texture rename it to RSKY2 or SKY2, and so on and so forth

I guess you will have discovered by now that DOOM2's maps are named MAPxx and not like DOOM's ExMx.

 

To show this particular original sky in your maps (MAP01 to MAP11) you need not do anything special other than placing the F_SKY1 placeholder as the ceiling texture.

 

However, if you want to use a new sky image for that range of maps, then find an appropriate image on the internet and rework it in a graphics app with DOOM2's PLAYPAL as a palette. Then resize the image to 256x128 and tile it horizontally.

 

After that is done, import into and append this image after the last entry, into your pwad with Slade3. Although not strictly required, the convention is to place this new image in-between markers P_START and P_END. You have to create the P_ markers yourself with New Entry.

 

Then rename this new image as RSKY1.

 

For example:

 

But notice that in the video I use the image format png, which is supported only by advanced sourceports, like GZDoom, Eternity, Edge, etc. The advantage of the png format is that it contains its own palette.

Actually, you're correct. The code is a real piece of fuckery with some absurd limits on textures above 65k, but it is doable.
