I’ve recently been rigging muscular characters, which has gotten me interested in researching muscle and skeletal systems.
I came across this article: Joint-Based Skin Deformation in Ragnarök Will Be Explained at GDC 2023
But I haven’t been able to find similar tutorials or articles, so I wanted to ask if anyone knows of any resources on this topic.
Currently I’m using RBF combined with manually-placed support joints, but I’m not satisfied with the results. I’ve also considered SSDR, but it doesn’t conform to a max influence of 4 joints — sometimes it assigns more, which makes the weights difficult to control.
Are there any other approaches I could try?
Ideally I’m looking for Joint-Based Deformation techniques suitable for Unity. Since Unity has a max influence limit of 4 joints, I want to minimize the use of blendshapes and solve deformation with joints instead.
