Ladder with Point Graphs

Hello there,

How would you implement Ladders for NPCs using Point Graphs?
I’ve searched a bit the forums and I could not get a clear answer.
At the moment the character goes to the base of the ladder, there I deactivate A*Project, move the NPC manually up and reactivate it when the NPC is on top of the Ladder, but it feels hacky and not very elegant.

Is there a better solution? I’m using Pro.

Thanks in advance!

place an invisible ramp underneath the ladder
