That doesn't seem to be correct. My area affected is bewteen 6,9 - 6,14 throught to 10,9 - 10,15 The meshes I used were level4.x4.y8, level4.x4.y12, level4.x8.y8, level4.x8.y12 They are laid out at follows: x4.y12 x8.y12 x4.y8 x8.y8 Hope this info works for anybody trying to figure out the whole wasteland mesh.
