JumpPoint tips for zeds

I am trying to use Jump Points so that the zeds will spawn happily at a point above the players, and then jump down to certain points.





I am really unsure of how to use these; I have checked other maps (West London and Manor for example) but have not been able to decipher what is actually acting as a target for the zeds from the JumpPoint.





Could anyone either explain to me how I can successfully create A JumpPoint and a target, or point me to a tutorial (I have looked for them but sadly the "advanced" features aren't well documented).





I am currently just using PathNode's that the zeds try and jump to from higher up, but they seem to be a bit clumsy with the jumps and end up falling over the edge of the walkway I am trying to make them land on...
