I would like some tips from other map makers on the best was to reduce Vrad times. Right now my Vrad time is almost 20 minuets. I have read over this page a few times but only understand half of it or so. https://developer.valvesoftware.com/wiki/Visibility_optimization I do have a couple questions to. Does a reflective texture such as metal/metalchrome001 cause a longer Vrad time? Do large open areas cause a longer Vrad time? I know the page talks about that but I want to hear it from another map maker.
