How to bind bones only on Unity 骨をバインドする方法
using System.Collections;
using System.Collections.Generic;

public class BindTest : MonoBehaviour

[SerializeField] private Mesh _mesh;

private int NUM = 10;
// Start is called before the first frame update

//各頂点にウェイトを埋め込む
BoneWeight[] weights = new BoneWeight[_mesh.vertexCount];
for(int i=0;i<_mesh.vertexCount;i++){
weights[i].boneIndex0 = Mathf.FloorToInt(_mesh.uv[i].y*9f);//対応するボーンのindexを入れる
weights[i].weight0 = 1;//その度合い
}
_mesh.boneWeights = weights;
Transform[] bones = new Transform[NUM];
Matrix4x4[] bindPoses = new Matrix4x4[NUM];
for(int i=0;i<NUM;i++){
bones[i] = new GameObject("hoge"+i).transform;
bones[i].parent = i==0 ? transform : bones[i-1];
bones[i].localRotation = Quaternion.identity;
bones[i].localPosition = new Vector3(0,(float)i/(float)(NUM-1),0);//meshに対してこの位置でバインドするのでこの位置は重要
bindPoses[i] = bones[i].worldToLocalMatrix * bones[i].parent.localToWorldMatrix;
}
_mesh.bindposes = bindPoses;
_renderer.bones = bones;
_renderer.sharedMesh = _mesh;
}
// Update is called once per frame
void Update()
