and as i said, if you want it that bad, mod like this is the perfect start to modding, because its one of the easiest you can make. The problem i ran into are custom colisions for some items and because am bad with 3ds max i didnt finished it.
i am currently working on mod that will do this, ie. place trash, rubble, broken walls, bushes, etc. its actually not that hard to do, but it takes long time to find every item so give me 2 months give or take
