OK I don’t personally but I have several actors (I’m calling them hot spots as once you click on them it merges camera to a static cam) - when the camera merges I usually get some of the other hot spots smash through the camera so what I want is to simply make all these actors fade away to zero viability… I have made them all go away at once but it looks clunky (see BP below). I’ve looked high and low and all I can see how to do this is set up some sort of dynamic material? firstly I have no idea how to do that and secondly surly there is a node i’m missing that just does this for you, it’s got to be a common thing? :-S Any help would be great! thanks

You do not. The input pin can take an array. You can also connect multiple object references to an input pin; this has the same effect as creating a loop yourself.
As for how to fade the object to zero:
