I looked at your .map file, found the problem:Cobalt wrote: Oh and if you look closely there are 'spikes' or portrusions at the 4 corners inside the circle. I didnt see a way to unselect them in the editor and I thought they were pieces only visible from the back, but now I see they are part of a brush area ...?
Here is its .map file if anyone wants to take a peek: http://pastie.org/9680116
You missed the four remaining parts of the center teleport field brush. It looks like spikes / protrusions due to an optical illusion relating to the ring frame showing through where there are parts missing from the center teleport field brush. They probably are broken up into so many pieces due to the "no concave brushes allowed" rule of Q1BSP.
