For example, if I want to make a simple 3rd person action/shooter up to 16 players on small/medium-sized map without any level streaming and etc - can I make all networking stuff with blueprints only?
Yes and it’s very easy. You have just to understand the “Replicate” concept. You can learn Network in blueprint on Youtube to UE4 Channel. You have 5 part and the ending is create un 3rd person game with bomb so you can learn here.
In my limited experience, if you are using a character class for the players pawns, its not very difficult. However, I’m having a great deal of difficulty getting non-character pawns to replicate properly, especially the transforms of a pawn’s submesh components. (I’m using tom shannon’s method for replicating pawn transform)
