Error message keeps on bugging me! Created 1 month ago2025-02-06 23:14:07 UTC by Dbebss

I've been trying to compile a map but i'm always being met with this error message
Bad Surface Extents at 24690/0 position (992,80,20)
I'm using the Jackhammer Editor, which is similar to the Hammer Editor.

This happens in one of two cases:
1. Your texture scales have a huge ratio (e.g. X scale is 4 when Y scale is 0.1). Texture scale should have an aspect ratio of 1:1, avoid extremes like 10:1
2. The texture projection axis is perpendicular to the face

In other words, a texture gets suuuuuper stretched, like spaghetti. This causes issues with lightmapping.
The first one happens when you use Fit on an entire brush which is very thin (e.g. a door which is very thin, like 4 units) - several sides will become extremely stretched. When you use it, please only select the faces that actually need fitting, usually it's just one or two faces.

For the second one, you need to change the texture projection, tick either World or Face in the Texture Application tool. You can also read Error: Texture axis perpendicular to face for a more visual illustration of this problem.

Thank you for the info. I'll get straight to fixing it.
