Hello. After separating assets in Photoshop, I use a script (PhotoshopToSpine.jsx) to export them. Then, I import the data and work using the generated JSON file.

However, I’m wondering if the following feature might exist.

When using PhotoshopToSpine.jsx,
names like [bone], [slot], [skin], etc. are applied in the JSON file,
and they work correctly when importing into Spine.

But when exporting as shown in the image below,

under the top-level skeleton, the structure looks like this:
root bone → firststep_main_nyangi~ fourthstep_main_nyangi

What I want is for each of these—firststep_main_nyangi~ fourthstep_main_nyangi, etc.
—to be separate top-level skeletons.
In other words, when importing the JSON file, there would be four separate top-level skeletons.

I tried using [skeleton] instead of [bone] in Photoshop, but that caused an error.

Is there a different JSX script that supports this?

Or is there a method I don’t know about?

Of course, I know that creating four separate PSD files would work,
but I’m curious if it’s possible to do this from a single PSD file.
