Okay I think I got this. In my content processor (which takes data from my importer) now I have this: BoneContent skeleton = MeshHelper.FindSkeleton(input); IList<BoneContent> bones = MeshHelper.FlattenSkeleton(skeleton); This will give you a list of BoneContent (bones), and it will have the right number of bones. From that, ...

Did you do any progress on this? I'm exactly in your same situation. My model.Bones array contains not only the bones, but the meshes as well. Thanks in advance!
