@xibei 请注意，您需要使用“Spine/Skeleton Tint Black”着色器并在“SkeletonAnimation”组件中启用“Advanced - Tint Black”。

请参阅此处的文档，第 7 节。 脊柱/骨架色调黑色`：
https://zh.esotericsoftware.com/spine-unity#%E7%9D%80%E8%89%B2%E5%99%A8

如果您使用“SkeletonGraphic”，请参阅“9. 脊柱/骨架图形色调为黑色`。

Please note that you need to use the Spine/Skeleton Tint Black shader and enable Advanced - Tint Black at the SkeletonAnimation component.

See the documentation here, section 7. Spine/Skeleton Tint Black:
https://zh.esotericsoftware.com/spine-unity#%E7%9D%80%E8%89%B2%E5%99%A8

If you're using SkeletonGraphic, see section 9. Spine/SkeletonGraphic Tint Black instead.

不客气。
You're welcome.
