I have 2 supported agents: 1 ( named: “First” ) has agent radius 200, agent height 300 and nav agent step height 60, and the other ( named: “Second” ) has agent radius 20, agent height 96 and nav agent step height 30. Hi, i am trying to rebuild my Navmesh so that my AI is not walking trough Trees or gets stuck in them. ) When I try to visualize the navmesh, only the default one seems I've not used Slope override in this manner, but the problem is most likley that you only have 1 nav mesh with the parameters of your default slope walk settings.
