Texture Alignment problem

[NoWits]

Sorry for the bump, but I tried building my level with ZenNode and all the node builders available with Doom Builder, but each one still produces the same annoying error in PrBoom. Is it because the textures are 96x96? And in two parts (48x96 and 96x48)?

Edit: I found a solution, yay!

That thread you linked to was a bug in ZDBSP that has been fixed for at least 3 years now.

Your problem appears to be related to your texture size. There's different ways how such odd-sized textures are handled so you need to be careful.

Doom and most sourceports can't handle drawing textures whose widths aren't powers of 2 (8, 16, 32, 64, 128, 256, 512, 1024, etc). They'll behave as if it's the next-smallest power-of-2 width instead, so 48-wide textures will be tiled every 32 units, and so on.

What about BIGDOOR1? That's 128x96!

96 units tall is fine, as long as it's not 96 units wide.

But as for height, since you mentioned it: The original "vanilla" Doom/Doom2 executables will have difficulty vertically tiling textures that aren't 128 units tall (though they can display them properly as long as they're not tiling), such as the 96-tall door texture you mentioned, or any of the step textures, but most sourceports have no problem tiling those now.
