Hey
heres something I started working on to practise with modeling.
Not much to go wrong with yet but just in case Im doing something completely wrong heres the pictures.
I decided to leave out one ledge to make the model lighter and less annoying in game (We all know the sidewalk ledges in Fallujah)
