How do you get AI to MoveTo target actor that is above ground, on another actor?

Thats a good idea, I do have a little problem tho.

The shelves should block off the AI character from moving into it, right now I did a hacky solution by putting a collision box there with a tiny bit of space for the Item to go on the shelf. If i use a trace down, I’ll need there to be a nav mesh on the bottom, but if I put the shelf it destroys the nav mesh.

I’m thinking of some kind of hacky solution to try to find the closet Nav mesh floor, probably like 4 line traces around my item and hope it hits something. HmmmMMMmm
