lowerbody节点是一个皮肤占位符 - 你认为这是不正确的吗？
Unfortunately I cannot judge what it should look like, I only see that the
lowerbody node is a skin placeholder - do you think this is incorrect?
If the project has been imported from a json file, you can open it in a text editor and check what Spine version it has been exported with, it should be one of the first entries in the file. You could then set the Spine version to exactly this version and try importing again, if you think that the import was incorrect.
Please let me know I misunderstood your question.
