The skeletalmesh of the CharacterPawn are begin no smoothed only visible in the server side tested in 4.15 and 4.17
Tried many different things and no one works, you can check it, feel free to create a game in ShooterGame and check it by yourself as listen server with a real client, the simulated network ping in the same computer is not affected.
You can see it in the Tom sample of Survival sample.
As already said that is why the post is there cause the problem keep, yes I already read that “fixes” that actually don’t fix it at all looks like. I’m not the only one with this problem there are others, but as always no one post nothing I have to post all.
I’m sorry but after 4 years reporting others problems and fixing others problems, I can’t do that anymore, I can’t record a video right now or send a test project. If someone can give you it, perfect, or even if Epic can check it. But sorry I can’t anymore work free for others to keep as always.
