I'm sorry for being anti-social.
I've thanked Fuddl muchly for his gtkradiant debian work.
I've also followed the advice given for blueamuse:
1/2 the lights fixtures are gone from the main room.
The spiral staircase room now has some stuff at the bottom (pipes and a rotating goop mover as seen in the main room).
The main room has another catwalk up high (detailed).
Textures are fixed in the crowded room.
Lights added for the phantom light sources in the hallway.
Some playerclip issues resolved.
BTW: what happened to that nice big map Diesel Power? It seems to be gone in the new nexuiz (that was an awsome map) (search didn't turn up anything).
