What do you mean by "paste the texture?" You don't paste a sky texture onto the ceiling, you use the flat F_SKY1, which is a special flat which calls a function to draw the sky. You simply just change what texture that function uses for the sky.

 

Sky textures are just wall textures, and you make them into sky by having a UMAPINFO file and defining skytexture = "texturename".

 

You will of course have to add the sky texture to your WAD, but that's usually no harder than adding any additional texture to the map.

 

See here and the video below.

UDMF doesn't have a designated blockmap lump, I believe. It's either combined in with ZNODES or skipped over entirely. What are you looking to do with the blockmap?

The blockmap has nothing to do with that at all. The blockmap is for collision detection.

Theres a couple routes of doing this but that entirely depends on the Source Ports you are aiming for. Some ports support HiRes addressing in wad format such as prBoom+ and the ZD/GZD family of ports. In those cases you can just tag a Vanilla sky and then let the Hi Res apply its version of the same texture name when you go to play the game. Its basically like applying a patch but without needing to apply an actual patch with pnames ( at least thats what I am remembering). The HiRes use is my most used format mainly because I do Zdoom family the most often

 

Another route is applying the texture in the map directly and just placing your sky graphic in the wad directly.

 

The other method is basically similar to the UMAPINFO but using the MAPINFO style instead provided you're aiming for MAPINFO compatible ports like GZD/ZD family.

 

Heres a useful graphic for both WAD addressing and Pk3 format build.

You can find some of the answers in this thread

 

In broad strokes think of the sky in DOOM/2 as a 360° projection, with images of various sizes

as outlined in SKY

Depending on the size of the sky image this 360° projection can be either the full image of 1024 or subdivided into smaller images of 512 (drawn twice) or 256 (drawn 4 times), where the image takes the top colour for a sky colour gradient then repeats vertically and takes the bottom colour for a bottom colour gradient

 

Spoiler

 

If you have ever used OBSIDIAN to generate a ZDOOM/UDMF map with the sky options then you eill have seen a generated skybox, which is a construct separate from the game area with a thing type 9080.

Of course, another sky is the GL_skybox in GZDoom which gives the sky a spherical projection with true top, bottom and side images. Like the one in Austerity
