PathNode loop

[palistov]

Yeah if it's a cross shape, you'll need a node in the intersection, so the grunt knows to path to the center and turn the corner. There's no real need for any other nodes, but the AI for detecting and investigating sounds/player sightings requires nearby path nodes, so populate the cross with a node every 1-2 meters, regardless of whether or not you'll actually tell the grunt to move to that exact location.
