Hello.  
I trying to implement lightning from point ot point in niagara. In cascade i can setup this with using Source and Target Module. BNut in niagara i cant find a way.  
I setup system with 3 emitter -2 for source location and 1 beam emitter.  
Then i setup event reciver in beam emitter and try to set postion parament in Beam Setup module in emitter swection.  
Editor see parametrs but beam dont react on them.  
How i can sent particle postion from events to beam End/Start ?
