not sure myself here however a navmesh is a trigger (according to radiant), I think the reply that AllOutWar gave he ment a navvolume I'm having the exact same issue they walk up the stairs but as soon as i walk onto lvl 2 they do the confused animation i can coax them onto it by letting them hit me they stumble onto lvl 2 and follow me no problem but they just wont go from stairs to lvl 2 them self's I've not set up separate nav volumes for each area just yet im using 1 large covering my whole map i want to get all the bugs worked out before i start making zones with individual nav volumes
any help from an expert would be much appreciated
