Hey, so I'm making a few maps and this problem occurs. Basically my wad uses cc4tex so I've copied the texture and patches lump into mine. Now I do intend to change some skys but that's not really the problem, in map01 i have a sky texture as the floor and the ceiling with normal flat and same height, the sky texture bleeds through and so I have the sky on that wall (works fine, idk if I got terminology wrong there)
then on map02 i wanna have like a few windows where you can see sky out of it, I do the same thing but it just shows the linedef texture, not the sky, even though that is the floor texture. I've tried numerous combinations of things but to no avail, I'm testing in a number of ports, this only seems to happen in software like odamex and prboom. Glboom works fine. any help appreciated.
