您好。你需要把你的图集的扩展名改为.atlas.txt。如果不这样做，Unity将不能正确加载你的骨架。正确的导出设置在spine-unity运行时文档的以下部分有描述:
spine-unity 运行时文档: 从Spine导出文件到Unity

Hi, you need to change the extension of your atlas to .atlas.txt. If this is not done, Unity will not load your skeleton properly. The correct export settings are described in the following section of the spine-unity runtime documentation:
spine-unity 运行时文档: 从Spine导出文件到Unity

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?

你能不能把你的Unity场景项目发给我们，让我们看看你的骨架到底是怎么显示的?: contact@esotericsoftware.com

Could you please send us your Unity scene project so we can see exactly how you are displaying your skeleton?: contact@esotericsoftware.com

我刚刚回复了你，但不幸的是，我无法下载你附上的文件。你是否有可能通过其他方式将文件发送给我们？

I replied to your email a while ago, but unfortunately the download page shows an error message and I cannot download the file you attached. Could you send us the file via another way?

谢谢你上传你的Unity项目，看来可以通过在SkeletonGraphic的CanvasRenderer组件中禁用Cull Transparent Mesh来解决。
Thank you for uploading your Unity project, it seems that it can be solved by disabling Cull Transparent Mesh at the SkeletonGraphic's CanvasRenderer component.

请参考Harald在本主题中的前一个答案。:
