Hello
Let me see if I understood, you are trying to cast to your flower to get the variable in it, but you can´t cast because the cast node doesn´t have an object of origin?
If this is the problem, try to use the nodes: “GetAllActorsOfClass” + “Get” and hook from the get to your object in the cast (actually, you probably will not need to cast anymore, the get node will do the trick)
see it here:
