Hello there.
So i was prototyping game with wave based system of enemies. Something like they are billions. Very fast i realized that just spawning actors is a rookie mistake. So i looked up and found something called Mass entity. But the documentation is weak and video tutorials are old and only thing that can be spawned is static mesh.
Can this mass entity spawner spawn Actual characters with animations?
Or what is the best way to spawn hundreds of enemies?
That is literally the million dollar question.
Mass can be used with fully animated skeletons. You may wish to check out a talk from Unreal Fest on Scalable MetaHuman Crowds that leverages Mass and skinned meshes.
With an interest in Mass, I would also recommend this talk about Mass and data oriented design with many great tips to assist thinking in that mindset. This was given from one of our Mass devs and features a project where everything is in Mass and no Actors (outside the ones the engine requires such as World Settings) exist in the level. It is a deathmatch between two teams of robots with rocket launchers and giant hammers. What is there not to love?!?
