我明白扩展的问题。然而，你的骨架在Unity中显示正确。这个骨架在Inspector窗口的预览中可能显示得不好，因为所有槽的混合模式都设置为Additive，但在场景中却很好。
I understand about the extension. However, your skeleton displays correctly in Unity. This skeleton may not display well in the preview of the Inspector window because the blend modes of all slots are set as Additive, but it is fine in the scene.
你能否检查一下Preferences 参数是否按照文件中的描述正确设置？
If it does not display on your end, it may be that the material settings are incorrect. Could you check to see if the Preferences parameters are set correctly as described in the document?
