Adding custom skys...

[SonicX8000]

I am really having a hard time with adding custom skys, am I doing something wrong?

I put them as a image and save them as a doom flat, but they won't show up, it just becomes a REDWALL.

I'm pretty sure that skies need to be saved as wall textures, not flats.

Save your sky as a texture with a name of SKYx, with x being a number. Then in your level header, type in "skynum = x".
