Sorry for the delayed response, I got side-tracked into setting up other gameplay systems/map building, and forgot to check back here to see if you replied yet…
Anyway, I tried adding the node as you show there, but it doesn’t seem to have any effect what so ever, movement over and around different height hexes remained unchanged (as in, the pawn couldn’t jump off cliffs, or walk directly to the highest point of a cliff-side, it still went around the long way to gradually move to the top). I even tried just setting it to 1 without the Int Select node, and it too had no effect. Note that I am still running in 4.7 (too lazy to update just yet…), so could it be something that you changed in the 4.8 version that I’m missing, or possibly a bug with 4.7 itself…?
