I have two BPs (A and B) which are communicating fine via Custom Events. In both BPs I have created a variable which I assigned the other BP to. If I add both to the scene the communication works fine.
Now I add BP A as a child component to a third BP (C) and the Trigger I used in BP A to trigger BP B returns: “Accessed None trying to read property … from function”.
My guess: Usually in my details panel of BP A under “Default” I have to assign BP B. Now, if I open BP C and select the child actor BP A in the details panel under Child Actor Component - Child Actor Template - Default I can see my BP B variable but I cant assign anything. It says “Editing this value in a class Default Object is not allowed”. But not sure if my guess is even close to what Im looking for.
Also tried Interfaces with different problems but als no solution.
