Compiling

It seems to work nicely but i had to add a half a second delay between the compiles so that the GUI could keep up. The dev build has been updated with this new functionality. source

Of course when you're doing a quick build to test something like the lighting of a particular room, there's no problem with using a fast compile. Regardless, I feel you should have your first compile be a full compile, just to ensure it's working and will be compilable in the future. source

The fact that Gentoo has a wiki page just for "safe cflags" should be sign enough to steer clear. The chances of you knowing better than the gcc and package manatainers in distros like Debian, RedHat, etc are pretty slim. source

As far as I know, they must be in the base UT folder. There is no reason you couldn't keep everything in a separate folder and just move a certain directory there when compiling it though. source

By Standard version you don't mean the Express Edition, right? That one comes without MFC which would explain your problem. source
