Texture wraps horizontally when it shouldn't.

[Ashurion Neonix]

So I have a 160 x 100 wall texture which I plan on using in a wad. But for some reason when I place it on a 160 x 100 sidedef it automatically wraps it as though it is 128 x 100. The texture only uses one patch and displays correctly in the editor but won't when ran in crispy doom.

I changed the patches to 256 x 128 by adding a random colour around the edge and now it's displaying correctly. I'm still confused about how it happened.

It requires a power of 2 horizontally. Something about compression probably.

Not sure which ports are affected.

Thought so. Same thing happens vertically but with different effects.

Vertically I think it's all about tiling with 128 units step, adding junk data. Not really happening outside strict vanilla, while this thing is more persistent.

It still all boils down to "incorrect texture size causes tiling issues"

This is a known limitation of many/most ports. GZDoom can handle this, but as far as I know most others cannot.

 

As mentioned already, maintaining power-of-2 sizing should resolve this.
