Yes, thank you Kell, I think I'll do that
I realize I'm bumping into what is probably all kinds of newbie problems, so it does make sense to read more about mapping and its related issues. I have always been a distant lurker of the Func Forums, but I think it's time to change that
I also realized I have to be MUCH more patient with VIS. I've taken a very basic map I had done, ripped almost everything and saw it still took a couple of hours to vis, so I'll have to make tests and let it run much longer than I thought was needed. The thing with my mod maps is that they are, by nature, a huge box (around 20% of the grid or so) filled to the brink with things, many of which are visible at almost all time... something, which I deducted was very tough not only on frame rate, but also vissing...
I'll keep you guys updated. Again, thanks a lot for the help
