So I'm trying to make some zombies in the crysis 2 editor and I need help making a flow graph that allows them to detect you a certain number of meters away and navigate any though anything. Heres what I have so far,

Also, when I try to do a custom hud/image it says "Replace me." I used every file format that it allows normally but still wont work. If anybody could help that would be great! (Thanks)
