thanks templar for clearing that up. can you remember how many nodes you used inside the city for example? or around a tree? i guess you are using 4 nodes around the trees or little objects and place them close to the edges?
my main problem understanding that is how to get georges system smooth. i guess it can be done either by clever node placement or by some kind of smoothing postprocessing the path... maybe you can help again

edit:
to make my question more clear i made a little picture:

on the left side the nodes around the obstacle are placed more away from it. if the player clicks somewhere near the top node it will make a big edgy circle around the obstacle. walking exactaly along the nodes.
on the second picture the nodes are closer to the object so the player will probably walk closer to it when trying to reach the goal.
is this how you did it?
also how do you reach the little red dot on the right side picture if the player clicked there but there is no node and make the movement smooth?
thanks!
