Why is this texture vertically unalligned in Chocolate Doom?

[Guest Unregistered account]

I've recently been remaking the Doom level Unholy Cathedral. Its visual design will be reminiscent of the original but the layout will be fairly original.

I barely even started and already I've found this small texture problem:

The animating fire textures (FIREWALLs, in editor is FIREWALLA) look as though they're unpegged but I actually aligned them properly in the editor. They appear as planned in pretty much every sourceport I've tried.


Well, Um... that would be two. Zandronum and PrBoom.



What's causing this?

IIRC, vanilla Doom has some issues with negative Y offsets on textures. I forgot the exact details but I think it might be the reason.

That's the FIREWALL textures, right? I believe the problem here is that their height is a non-standard number: 112. (The standard numbers are the powers of 2: 32, 64, 128, etc). Such textures work a little bit differently when aligned. I'll be back if I find more info on this.

edit: oh, I think it's a combination of what Gez and I have said. Non-standard height texture + negative Y offset = the game displays it differently from the editor.

Please use a dedicated image hosting service, not a general file hoster like MediaFire, if all you want to share is a picture.

Or post a thumbnail for forums instead of a download link, so as to not irritate printz.
