| boneWeights | 要填充的 BoneWeight 结构列表。 |
获取网格的骨骼权重。
如果要避免在每次访问时都分配新数组，请使用此方法而不是 Mesh.boneWeights。
如果此网格定义了骨骼权重，则每个索引处的骨骼权重对应于具有相同索引的顶点。否则列表会为空。
此属性使用 BoneWeight 结构，这些结构仅表示每个索引的 4 个骨骼权重。在数组的每个 BoneWeight 结构中，骨骼权重采用降序，加起来等于 1。如果影响顶点的骨骼低于 4 个，则其余每个骨骼权重必须是 0。
若要对每个顶点使用更多或更少的骨骼权重，请使用较新的 Mesh.GetAllBoneWeights 和 Mesh.SetBoneWeights API，它们使用 BoneWeight1 结构。
另请参阅：Mesh.boneWeights、Mesh.GetAllBoneWeights、Mesh.SetBoneWeights、Mesh.GetBonesPerVertex、ModelImporter.maxBonesPerVertex、QualitySettings.skinWeights、SkinnedMeshRenderer.quality。
