if you are using an action actor then make sure that the actor is choosing the right effect that you are using and go to the events the check if the beam is created after the effect is started and it end after the effect is finished
some models may not shows up if you choose a very dark color like vortex ( specialy if you are using low graphic ) so dont go too dark
