TGHoly I try to import json file export from lastest version to 3.7.94 but it give me error. "An Error occurred while importing the skeleton. Please be sure to choose a valid skeleton JSON binery file."
Mario Spine JSON and .skel exports are not backward compatible. If you to import a Spine JSON file from a newer Spine version into an older Spine version, you will have to use the JsonRollbackTool as described here: Spine editor and runtime version management
