thanks for tips and comments, Im at the moment makeing more pathways and expanding some so that mister fatass can access more areas
and im adding stuff and detail here and there.
while doing that I found out something kinda annoying:

If you can find where the aim is. that place of that prop model isnt penetratable, not for weapons or anything. which would be annoying since its in the middle of the map where prolly some fighting will be going on.
If you dont know how to add a collisionmodel ask me

thanks
