When I compiled upland_rc1, vvis took 10 minutes. Now, when I'm compiling a new version, it's taking 2 hours and 10 minutes. Going back and compiling rc1 again still takes 10 minutes, so it doesn't seem to be a problem with vvis. I haven't really made any major changes since rc1. I added a few areaportals, but I tried removing them and that didn't help the vvis time. It's mostly just added models and things like that. Does anyone have any idea what could cause it to take so much longer?
