So I am very new to Blender and 3D programs in general. One of the models I'm using to help me with learning how models work and how to rig them came with a bone rig already setup. However... this is what I found. I tried fixing them using the VR-Chat CATS plug-in, but even that didn't work. I want this to be a learning experience, so I would appreciate any and all help regarding this issue.
