Yes, it is possible it take a few seconds to recalculate the mesh…
But in the other hand the NPC can go in the same path as the player.
So, i want test it then i decide if worth it.
I see that in Unity it can be done relatively easy.
I also found this in Unreal. The video is old (from 4 years ago)…
And the owner explains a little about what he did… But the explanation is too weak for me. I need more details.
Anyway, I hope that Unreal solves it easily (At least like Unity).
Thank you very much for your comment!!
