After some good playing in the sig11's test server, all my guns deserve is some flashy colors
I don't know if I can either reproduce it, one day.
I don't think it can be a map problem.
Perhaps it is related with the graphic card, the driver, the Q3 version (or new implementation) ?
The screenshots were taken from my FreeBSD 6.1 machine, with Nvidia 6600GT, Nvidia driver 1.0.8178, CleanQ3 v0.5.2 (ports/games/cleanq3)
After restarting the game, all is back to normal.
Just strange it is.
PS : Thanks for posing, Breli ^_^
