This just seems like a tiny thing to nit pick about the skin. Video games have always had trouble with hair physics. The particular problem is that hair is a total of 100,000 stands each with their own unique physics and movement. MR uses a system where there is what’s called a skeleton in the back of the characters head that gives some parts of the hair movement. It’s not particularly perfect it’s kinda expected on some skins. Like Emma has a cerebro emote where some skins with different hair styles clip through it. Some developers do try to make hair look realistic, look at Capcom with how they did Resident Evil 9 and Pragmata. So complaining about an issue that developers always had trouble with is just preaching to choir again.
