雨之师 I'm sorry to hear that you're having trouble. I am afraid I do not have a clear understanding of what is "wrong" just from your description. Have you read the FAQ section of the spine-unity documentation?: https://zh.esotericsoftware.com/spine-unity#%E5%B8%B8%E8%A7%81%E9%97%AE%E9%A2%98---FAQ
If you find something strange immediately after importing your skeleton data into Unity, it is often because the export settings in Spine and the project settings in Unity do not match. If you could provide some screenshots of the export settings on Spine and the project settings in Unity (especially the Spine section of Preferences), we might be able to see what the problem is.
