I've got a problem in radiant.. Whenever I set the portal_nodraw texture on a brush/face, that brush/face disappears from Radiant. This only happens with portal_nodraw. Because it's hard to explain in words, I just made a video of it and put it up on Youtube.
If anyone has just the slightest idea why this is happening I would be happy to hear.
I also copied a "clean" version of COD4 to a different map, reinstalled the modtools from scratch and it's still happening!
If I copy the COD4 folder with the modtools installed to another computer, it works correctly. So I'd say it's fair to assume it has something to do with the configuration of this computer but I can't understand what external configuration would make Radiant display such specific behaviour. I've tried using ProcessMonitor to capture some information but nothing happens when I click portal_nodraw (process-wise).
Anyone know what dependancies Radiant has, what I could reinstall to stop this from happening (aside from Windows
