TrenchBroom - A Modern Level Editor for Quake.

The title says it all, found it in the CodeProject newsletter

It's a cross-platform editor, for those who are wondering about the Mac OS UI.

I played with it a bit (going back to Hammer was a bit disappointing), sadly, I would get an error every time I tried to load gfx.wad from my Quake pak file (Invalid mip dimensions?).

I will give it a try, looks great from the video.
