Using particle system to array objects on vertices I would like to use the hair particle system to make a random 'fence' so at every vertex I add a particle which comes from a group. It works but it does not add a particle to every vertex. (The number or particles is the as the number of vertexes of the base object) 

Is there a way to fix it?

Thanks in advance!
You need to uncheck the "Random" box.


(Note: this answer was posted before the question showed that "Random" was unchecked already.)
