Building walls

[Thorite]

you can also create the walkthrough wall by editing the map.cfg go to mapmodel number 126, take out the 4 at the beginning of the line and replace it with a 0.
Then /newent mapmodel 126 height-in-cubes-# texture-#.
So /newent mapmodel 126 0 25 would be a 4x4 model of the tile texture at ground level.
