Error: Texture axis perpendicular to face Last edited 9 months ago2023-07-05 14:39:54 UTC

For some reason a texture has been rotated on the face of a brush until it is "stick out of" the brush face. Causes are usually, but not always: vertex manipulation, clipping the brush, carving the brush, importing a prefab, and sometimes rotating/skewing a brush with more than 6 sides - like a cylinder - without texture lock on.

Often this error can be fixed using the "check for problems" dialog (Hotkey: Alt+P). In the rare case the error isn't shown, you will need to search for the error manually.
