How do you fix a cut sky?

I've been seeing this problem in a while but I don't know what to do with it. How do you fix this?

So here's the problem. RSKY1 is actually a something called "patch", not a texture per se. Textures are assembled out of patches in a lump called TEXTURE1 (And sometimes others of similar names) and the actual sky texture is called SKY1 and is set to have size of 256x128 and consists of a single patch called RSKY1. If you want your sky wider, you will need to copy TEXTURE1 lump into your wad and edit it there. In your specific case simply editing the texture dimension to be 1024x128 or whatever your height it (I think 240 pixels tall sky only works correctly in gzDoom)

The sky image can be just about any size when rendered through GZDoom. However, for a simple sky image such as this, it is best to stick with a size of 256x128, as in the original DOOM2. As well, the image must tile in both directions, or at least horizontally, else you see those jarring breaks. It should also tile vertically when one can see below the floor.
