Hi

Sorry to my English.

In this video :


The characters Ai move well when the landscape mesh in set no colision. So there is a navmesh on the moutain.
When i activate the colision on the landscape, the ai character don’t find the good path on the navmesh. Because there are a navesh and another above.

I use au move to in the behavior tree.

Somebody can help me ?

Thanks and sorry to my English

Hello

Thanks i will go to read that.

I just correct the bug.
After the ai teleport, i must update the Ai path on the navmesh. To do this, i activate the move to and that s good.

Problem solve

Did you found a answer or got this “fixed”? I have the same problem, I have a structure with two floors, both floors have a valid navmesh. But when a location on the 2nd floor is picked and AI does a AI move to, AI will go to the exactly same spot in x-y coordinates, but to the spot in the lower floor. So it seems AI move to is not understanding Z axis when there are nav meshes vertically stacked for floors.

As I read, after “updating you” nav mesh everything was fine? Or did you also changed your nav mesh to only have one floor again?

I am also having this issue, i have roads with overpasses and if im fighting a melee ai under the overpass, sometimes the ai moveto send the ai to the TOP nav mesh instead of just running 300 ft forward to me.
its unfortunate that the original poster left such a vague, incoherent, and frankly useless “fixed” update.
