# Mesh.boneWeights

매뉴얼로 전환
public BoneWeight[] boneWeights ;

## 설명

The bone weights for each vertex in the Mesh, up to a maximum of 4.

The size of this array is either Mesh.vertexCount or zero. The array is sorted by vertex index.

This property uses BoneWeight structs, which represent exactly 4 bone weights per vertex. Within each BoneWeight struct in the array, the bone weights are in descending order and add up to 1. If a vertex is affected by fewer than 4 bones, each of the remaining bone weights must be 0.

To work with more or fewer bone weights per vertex, use the newer Mesh.GetAllBoneWeights and Mesh.SetBoneWeights APIs, which use BoneWeight1 structs.
