QualitySettings.skinWeights

描述

The maximum number of bones per vertex that are taken into account during skinning, for all meshes in the project.

The value can be either One Bone, Two Bones, Four Bones or Auto. Note that higher bone counts may have a performance cost, especially above 4 bones per vertex.

This setting does not change the underlying mesh data; it only affects the number of bone weights that Unity uses when performing skinning. This means that a mesh can have bone weight data that is unused due to this setting. You can change this value at runtime.

通过使用 SkinnedMeshRenderer.quality 可以为单个网格设置此值。通过使用 ModelImporter.maxBonesPerVertex 可以设置网格数据为单个顶点存储的最大骨骼权重数量。

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Set skin weights to one bone for all Meshes
        QualitySettings.skinWeights = SkinWeights.OneBone;
    }
}
