I got"orphaned skeletons" warning

Nick

I merged two skeletons and removed the old one. Only have one skeleton in the project now. When saving the project, it show me this:

Don't know what it means. Did I do something wrong?
Thanks

Nate

You didn't do anything wrong, Spine did. Spine found a reference to a skeleton that is no longer in your project. This is bad and can cause crashes when you try to manipulate whatever it is that has the bad reference. If you shoot us your project file, we can take a look and likely fix up the references.

It would be extra helpful if you knew what actions you took to get it in that state. For example, did you drag something from one skeleton to another? It will probably help you narrow it down once we can tell you what thing has the wrong skeleton reference.

I was merging skeletons. They have skins on them. I imported two new skeletons using json data. Since the export have skin tag used, I pre-added the skins to the target skeleton before dragging things across them. (Otherwise, dragged attachment will became default skin. It seems don't automatically create the skin for me if skin not found) Not sure if it is related. After that I rig the character as normal and at last I delete the two empty skeletons. Warning start popping up from time to time after the deletion.

Here is the project with images filled black.

Thanks!

When opening the project, Spine lists the problems it found:

These attachments are in the HomeTown_Girl skin, but the attachments think they are in the Harbour_Boy skin. The Harbour_Boy skin is actually in the Harbour_Kid_Boy skeleton that should no longer be in your project, that is why you saw the "orphaned skeletons" messages.

It appears there is a bug somewhere. We would love to fix it, but need to narrow down where it occurs. Would it be possible for you to provide files and steps that cause the problem? Eg: open a project, import a skeleton, drag something from one skeleton to another, save, see "orphaned skeleton" warning, re-open project, see list of problems like the above.

I could try reproduce it on next batch of character. Btw, I saved the project and reopen it, also see those warning but no attachment is missing visually, every skins seems working fine.

The suspicious action I did on the editing this time and never did before is that I turned on all the skins on the "skins view" (the pin) and turned on "show all skin attachments" filter before I clone attachments and assign them to other skins. Those skins share some common sprites. I think this action could be related. Other actions are just common daily rigging.

Hello,
I'm having the same warning. In my case there are no skins.
What I did was to open a new project and import other projects into it. I am using spine for just a few months now, so I wouldn't be surprised to find out if that's not what I should be doing to bring my skeletons and their animations together; but that made sense and I don't know any other way.

I should tell that everything seems to work just fine in the editor. But it gives this warning when I open the project, and when I export, then I see some skeletons are missing.

Also, I started this project in 4 beta version and as of today I updated to 4 stable. But warnings came before the update (and after).

What should I do now?
Thanks.

Nate

@belboteque, sorry for the late response.

The warnings mean Spine fixed up something in your project. If you can show us how you achieved those problems, then we will fix it right away! For example: your project has no warnings, you import another project, take some actions (maybe move things between skeletons?), save, and then when you re-open the project you see the warnings. We need the project files before you do those things and the list of steps we need to take. We would love to fix the problem!

To follow up, we got the project and made a number of fixes in 4.0.04. Cheers! :beer:
