I have been trying to find or figure out how to make objects non walk thru. i.e. fence as deco object not regular fence for In Game World Editor. I am trying to herd my sims to cross a bridge in a "park" to cross from one side of my world to another side over water. The world is premade and for some reason I can't get it to work in CAW so I made a lot from one side of the river to another. The sims goes down both sides of the lot but not across the bridge. Can someone recommend something or info on what I should check in s3pe? Thank you for your help.

All objects added in Edit Town can be clipped through even if they have bounding boxes/footprints that would prevent that when placed on a lot, because the game does not recalculate routing data for the world lot.
Such changes have to be made in CAW, unfortunately.

@CardinalSims Thank You for the info.
