How to dynamically place nav link proxies?
I am trying to use nav link proxies and I search for a way to place them without manually placing them in the level. So I want to put the nav link proxy in a blueprint and any time I place the blueprint it's configured correctly. If you have many same objects which all need to use nav link proxies this makes sense I guess. And I also want to spawn these blueprints dynamically while the game runs.
But how can I do this? I actually always thought there would be something like a "nav link proxy component", same as there is a "nav modifier component", but I can't find any "nav link proxy component" and I also can't find any other way to spawn one from blueprint. Where is it? I really need it, I just never thought about this being a problem before.
I just noticed I can create an actor based on nav link proxy, so I could add this actor as a child actor component to my blueprint, but then the problem is I can't set the left and right point in the viewport because it's a child actor component and not a nav link proxy. Now I can get the real nav link proxy actor in blueprint from the child actor component, but then the problem is that there is no way to define the left and right point!
After clicking on a nav link proxy in the level I see that there seems to be an array of "PointLink" structs (?) inside where I can set the points, but I can't get and set these struct from a blueprint which inherits from "nav link proxy". Why?

I don't think there is a way to do it purely in Blueprint, as the positions of the links (point or smart) are not exposed.
You would have to create a small C++ helper class to do just that.

Same problem! Looking for a way to let AI drop down off high ledges without placing a bazillion proxies. Seems like it should be easy.

I have the same problem too. Any ideas?
