#1 I noticed all the units vests have a tiny capacity (about 3 mags max) and spawn default with no ammo.
#2 some buildings lack ai path finding
#3 Shooting at any of the custom objects givers the "default dirt splash" of a fire geometry without defined rvmats, the default fire geometry is impenetrable so windows like the bus stop glass and thin wooden doors can't be shot through.
#4 it seems the buildings don't have shadow lods inside them, this isn't a huge deal but it gives a sort of sun illuminated lighting on the interior of the buildings as well as the character and any objects inside.
#5 some buildings and objects don't have a roadway texture applied, which means you don't get footstep sounds and interior gun/rain sounds. not a big deal but always good practice to have
#6 the (sulfur?) orange rocks have weird collisions
#7 it doesn't look like the detail lods drop enough over distance, generally buildings should turn into boxes in their last lod or two. It's hard to tell if I might be missing it since it's hard to see but I can see some lod switching which is good

These are some of the things I encountered testing in eden

Otherwise a fantastic mod and I'm glad to see something new, especially the custom buildings and animals. If you need any help I can provide some advice on how to fix these issues and others.
