I think you misunderstand.
If I place an obstacle and its simulating physics and it DOESNT affect navigation. The AI will walk through it… which is what I WANT as they’ll simply kick the object out of the way. However if I cant set affects navigation, then they will simply not even attempt to walk up to it at all since it breaks the nav mesh.
So I have to MANUALLY set each traash can, each park bench etc and uncheck affects navigation. Meaning I can’t automate that kinda stuff, nor can I randomize it at run time since I can’t spawn static meshes and set them to not affect nav when spawned.
