I have been using Maya PLE for a few months, now, on and off when I have time (mostly at outrageous times at night...). The bridge is in fact modelled after the GG bridge. I am still trying to decide how much detail I should include, like lamp posts, beams, etc. The system gets really sluggish when the number of polys starts piling up. In fact, does anybody have ideas on a way to put enough cars on the bridge and with enough detail to look ok, without completely choking the system?
