MAx In Spine, there is a principle that each skeleton is exported as a single skeleton data file (either a JSON file or a binary file). To consolidate multiple skeletons into one file, you must manually move all elements from each individual skeleton into a single one and then merge them. However, merging skeletons comes with several limitations, making the process quite challenging. For example, while bones and slots can be moved, constraints cannot be transferred between skeletons. Additionally, when using skins, only the attachments from the currently active skin can be moved, which further complicates the process.
It would be helpful if you could explain the reason why you want to consolidate all skeletons into a single JSON file. If you let us know what you're trying to achieve at runtime, we can offer more specific advice.
