Set it something like 1, and it’ll swing and go absolutely insane! You also won’t want the same settings on every physic body. Set this to something like 1000, and your hair won’t move, because it’s too heavy. The simple explanation of what hair mass is, would be: weight. I’ll start by explaining mass, and go on from there. Next up, we have the important part: physics. Position and Rotation shouldn’t be messed with, as they both simply mean where your body is on the hair, and you don’t have to change that, and if you do need to change it, you should do it from the PMX view window. Good physic edits will have bigger sizes going down on the model, as most hair meshes are thin at the top, slowly getting bigger down at the bottom. The SIZE of your physic bodies will determine how good the collision physics on your MMD model are. Going from top to bottom, let’s start with SHAPE: Shape is almost always irrelevant to actual physics, just set them to cap (which is a pill shaped looking physic) and you should be basically fine). ( mini side note: You will never need repel or friction, whether your making skirt or hair physics, and although I’m referring mainly to hair physics, everything besides the mas values can be used for skirt physics, as well.) With those tips out of the way, let’s begin the main part of the tutorial! Body Physics The part your looking for can be found about 4:30 into the video.

The video: “MMD Hair weighting tip”by YouTube’s Digitrevx Trev Weight mode just doesn’t like some people, specifically: me!)

( pro tip: if it doesn’t work with the weight mode set to weight, try re-doing everything (the weighting) except in normal mode instead. It tells you exactly what you need to correctly gradient weigh hair. It’s easier to explain if I show you this video, below. Do this several times, parent and connect them all together, and you should have a nice balanced set of bones.ī: Gradient weighting is almost always the best way to go in terms of weighing you hair. Let’s say I have hairbone1, and hairboneend… I parent hairbone1 to the head, and hairboneend to hairbone1, then select both bones, go to edit, bone, and create middle bone. You’ll want to have weighted your hair and added bones, but there isĪ: pro tip: Correctly parent and position bones. Let’s go tab by tab in both the body and joints tabs, but before we do that, let’s go over something very important. Most physic tutorials will tell you “put these numbers in and you’re good”, but what’s any use in knowing the numbers if you have no idea what you’re typing in?

The body and joint settings of your physics are what make them look smooth and flowing.
