This is probably simple, I want to remove some unused space since it takes up lightmap space in my game

enter image description here

Basicly I want to remove the red part but keep the green withsame texture cordinates so I need to correct UV somehow.

Mesh looks like this in blender 2.8

enter image description here

So basically I want to shrink down to the 3D cursor, but also remap UV.

edit: I solved it just because it was even measures. The wall is 4 meters tall and the wall I want is 1 meter. So i moved down the vertices, now the UV is wrong. Than I moved the top vertices in the UV mapping down from 1.0 to 0.25. Must be a more bullet proof way of doing it?


Use a knife or loop cut to break the square in half, then delete the extra vertices.

  • $\begingroup$ Loop cut sounds like something I wanna to, can you tell me about the process? Thanks $\endgroup$ – Anders Apr 12 '20 at 20:02
  • $\begingroup$ i found some reasources about it. But I need to create my cut at exactly 1.0 meters from ground plane. $\endgroup$ – Anders Apr 12 '20 at 20:11

    $\begingroup$ In that case, can you turn on snap to grid? docs.blender.org/manual/en/latest/scene_layout/object/editing/… $\endgroup$ – Denis G. Labrecque Apr 12 '20 at 23:10
