While a basic minimal set of bones is common for most models, there are individual differences. Parent/child relationships are not the only place where this is important, as we’ll see.Īdding to the answer above: existing motions rely on assumption that the acting model has the same (or at least, no lesser) set of bones and facial expressions as the one that the motion was designed for. In order to know where the child is, we need to first know where the parent is. We all know that children need to follow parents, but why? It’s because the position of the child depends on the position of the parent, but not vice versa.

What does that mean? It means that they need to be in a particular order. I still find myself thinking of them as lines– and making mistakes because of that. If you think of them as lines, you’re going to run into problems over and over again. Bones are points around which other points (vertices and other bones) rotate. Those lines leading to the child or offset are meaningless as anything except a visual aid. They should have been called “joints” from the start, but it’s too late for that now. MMD uses skeletal animation, so a big part of rigging in MMD is about the creation and placement of bones. Riggers take care of all the jobs that make the animator’s life bearable, so that the animator doesn’t have to push individual vertices around. (Unfortunately, us amateurs don’t have the luxury of passing our rigging on to the specialists.) In the world of professional 3D modelling, it takes a whole team to create a single scene.
