The thing that I am trying to do with this is I am trying to join an object to another object within my project as need to get later down the line other objects to be able to join togher within the level but I dont know why the code is not working the is a problem with the fuse nonde and the attach actor to actor how can I resovle this problem and then proced to get more actor to fuse together.
Can you show us how do you set your variables named “BP Box Small” & “BP Box Large”?
They are actor ref within the player blue print as I have been setting them up I have mainly be getting the actor ref to connect to the other node within the blueprint I have not yet chsen to set theses nodes yet.
Yeah that’s why you get the accessed none error. You should assign actors to them.
ok
The actors now have the right refs for them and now the only error that is poping up is for the fues node.
Seems like the access issue persists tho, can you show how do you set them 
No no that’s not what I meant. Like I said, you should get the Set type nodes for your object type variables named “BP Box Small” & “BP Box Large” and set them to whatever objects you want them to reference.
right
I have the actor ref set to the actor blueprint for the variable.
Yeah but currently no object is assigned to them. What are the two objects you wanna access anyway? Depending on the context, you can choose to cast to their blueprints, detect them with line traces / collisions, or if the thing you’re trying to do is fit to be inside the level blueprint (which I assume is not but anyways) you can directly get references from there.
