How to do instances

So I am trying to do an instanced mesh, but I am unable to “fill” my instancedMesh property by some static mesh and I am unable to find one simple example of how to do it / what are the restraints. But maybe I am doing it wrong entirely? I want one mesh (in future one actor) spawned on many locations… It works with static mesh, but it makes great impact on performance due to sheer number of replication.

So I have finally found the solution. I actually don’t get how that setup part works, as it goes kinda “backwards” from dataflow point of view, but it works.
