# skinWeights

> Skin weights import options.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.7/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public ModelImporterSkinWeights skinWeights { get; set; }
```

### Remarks

To import more than 4 bone weights per vertex, set this property to [ModelImporterSkinWeights.Custom](/engine/6000.7/script-reference/unityeditor/modelimporterskinweights/custom.md) and set [ModelImporter.maxBonesPerVertex](/engine/6000.7/script-reference/unityeditor/modelimporter/maxbonespervertex.md) to the required number. You may also limit the number of bones to less than 4, or set a threshold for the weights via [ModelImporter.minBoneWeight](/engine/6000.7/script-reference/unityeditor/modelimporter/minboneweight.md).

Note that [QualitySettings.skinWeights](/engine/6000.7/script-reference/unityengine/qualitysettings/skinweights.md) and [SkinnedMeshRenderer.quality](/engine/6000.7/script-reference/unityengine/skinnedmeshrenderer/quality.md) can limit the number of bone weights that Unity uses for skinning. Ensure that these values are set to Auto, if you want to use more than 4 bone weights per vertex.
