Lets say i wanna make an AI monster can crawling on the ceilling and find a way to a point which also on the ceiling . How can i archive that with navMesh ? Is it possible to only use blueprint system ?

There’s not real support for it, but you can easily fake it by having navmesh just under the ceiling. Close enough so that AI on the ceiling can find a path, but far enough to have it generated at all. Or just generate navmesh on the other side of the ceiling, pathfinding should pick that up.

thanks man ! guess i will have navMesh genereated on the side of the ceiling . BTW , what about AI crawling on the side wall ?

There’s no way to have navmesh on walls currently. You’ll have to use navigation links, which has its downsides, like AI not being able to pick up a path from a “middle” of navigation link, or finding a path to a specific location on a wall. It will just give you means of finding paths between the floor and the ceiling.
