more nav improvements

Updated Nav so NPCs dont get stuck on some shit, and also did a nav_analize to hopefully fix some other shit idk

-finally added proper navmesh!
-a few other tweaks here and there
-made a menu icon for the map

Finally gotten around to updating this insanity of a map

added proper maplist thumbnail finally

added proper navmesh, more navmesh will be added soon

rescaled the giant tower to similar size in the L4D2 version of the map

rescaled one of the buildings on the main area to fit roughly how the L4D2 version is

no more bullshit skybox issue

optimized a bit so some shit might be fucked since the last version, oh well lmfao

attempted to fix a few things with the map, currently there isnt a giant grey texture in the sky anymore, however that now leaves players able to see the normal map now, which it would be fixed if hammer wasnt an ass, hopefully if the change went through, i added 2 "ramps" in the map, and the giant flatgrass building now has a small ramp to go over the gap at the top incase players wanted to drive up it or something

Da shitto Publisho
