Hey, sorry for my late reply.
So I’m looking for a similar behavior like the “Filter by Class” Function from the Datasmith plugin. Here is an Overview:

On one hand, you get an Array of Object References and a class to filter, and then it returns the filtered Array with the coresponding object reference type.
I’m basically looking for a function that replicates this behavior with single objects, not Array’s.
I hope this helps you understanding what I want.
But again, I’m not sure if this is possible with simple Blueprints…
