頂点の距離は、スキンメッシュの頂点位置から移動できる距離です。
The Cloth component makes sure that the cloth vertices stay within maxDistance from the skinned mesh vertex positions. If maxDistance is zero, the vertex is not simulated but set to the skinned mesh vertex position. This behavior is useful for attaching the cloth vertex to the skin of an animated character. Default: 0.2 Range: [0, inf).
