gm_bigcity Icon, Cubemaps, & NavMesh
Adds all the missing content into gm_bigcity!
With this addon, there is the icon, the cubemaps, and the navmesh. The navmesh took over two days to develop, and I am certain that every building was covered. There is not much else to this addon, but it should fix a lot of things.
Post a comment in the Bug Reports discussion if there is a problem!
