I've attached two test cases which show examples of brushes/faces getting distorted when they appear compiled in-game. The third case shows an example of brushes disappearing for reasons I'm not sure of. The maps should be placed into /maps/assets/ and compiled there. I've attached a .ufo file to make all three maps available in skirmish.

1. test_streetlights.map -- If you look at the top of the yellow pole, where a smaller white pole begins, you will notice some distortion on the vertex position. This only happens on the one that has not been broken into different levels and given visibility settings to only appear on the appropriate levels. My suspicion is that it is because it is a very long and thing pole.

2. test_busstop.map -- From one side of the glass, the faces are distorted. From the other side they are not. I'm not sure why.

3. test_brokenground.map -- Some of the dirt brushes at the bottom of the pile, where it spills out, disappear when compiled.

I've just added a fourth example that I remember stopped me from continuing to work on alien base ages ago.

4. test_pipeend.map -- It's supposed to be the curved end of a pipe or rounded container. As you'll see, two tiny gaps are created in the end.

One of pipe ends fixed by merging into single brush, other is left as is for comparison

Uploaded a fix for pipe end made by a hacked version of merge tool. As far as I can see, verts are still in place (and therefore on grid), so you can attach it seamlessly to other geometry created in similar way.
IMHO, it could be better to have it as official tool in Radiant, but it's qurky right now and prone to generating strange geometry :)
Also, phong surfaces are somewhat broken now (which is obvious by looking at the pipe). Maybe it's time to finally fix it ...

The fixed pipe end looks very good in-game. Thanks for that fix.
