I toyed around with the NY banks last night a bit, it's going to be extremely challenging to do those correctly because of the round angles on the corners - obviously we all know the editor is forgiving when you're angling a custom qp inwards however outwards there's nothing to properly match up the corners. I was using rocks, the original banks were set stone anyway that somebody smoothed out with concrete but the unforgiving collisions were not having it. Have at it OH, I may still do the SF banks but keep messing with NY...
