Can't import skeletons

T.Fly()

Latest GDScript Spine binaries as of 24/09/2023
Spine 4.1.23
Windows 11

I can view the Spine runtimes examples. What I can't do is import my own Spine skeletons made in Spine 4.1.23. I get the following error:

I'm mostly trying with .skel, but .spine-json also doesn't work. I've also tried with several other skeletons I have in my possession, and none import. These same skeletons work just fine in Unity runtimes.

Same issue with sample SpineBoy:

I'm not sure why this D:/a directory is referenced since my Godot binaries reside on C disk. Moving Godot .exe from C disk to some other drive didn't help either in case this is some very weird permissions issue.

~~Fixed it by disabling the pre-multiply alpha checkbox.~~ Still not working unfortunately.

It seems to be working even with the import error popping up. I can create the SkeletonData resource and assign the .skel and atlas. What confused me was that the imported files don't have the Spine icon like in the official documentation so I thought none of it is working together with the import error:

Yeah, I see this error message as well and I have no idea where it is coming from. I also have no idea why our icon doesn't show up in Godot 4.x. We supposedly do what the module documentation tells us to do (and it works for 3.x)

I've opened an issue here:

Mario Hi, I am affected by this issue so I went through the official Godot repository to try and find any open issues related to this. I didn't find anything that could specifically explain this behaviour. Did you maybe try and open an issue in the repository over there with a description of the problem? If not, that might speed up the process of fixing this problem.

I have the same problem, i need help please!

umbekannt Ignore the error for now, everything works both in the editor and in the build. Create SkeletonData Resource, then assign .skel or .spine-json and atlas to it. Add a SpineSprite node to scene and assign the newly created resource to it. The skeleton will show up and work as intended.

Hopefully, this can be resolved soon.

Godot 4.1 doesn't recognize any skeleton format, neither .spine-json nor .skel

T.Fly()

umbekannt You have .json instead of .spine-json. http://esotericsoftware.com/spine-godot#Exporting-for-Godot

Note: You should prefer binary skeleton exports over JSON exports, as they are smaller in size and faster to load. If you must use JSON, make sure the file extension is .spine-json instead of .json. If you have an existing project that still uses .json export files, you can use this Python script to convert it to the new .spine-json extension.

And try one format at a time, delete contents in Godot, then reexport with correct file extension.

I have the same problem with the .spine-json format 🙁

umbekannt uff, then I dunno. Try resetting Spine export Pack Settings to Default. There's a button for it, then disable the Premultiply alpha checkbox. There's a note in docs that premultiply alpha is not supported. That's my last guess.

It still doesn't work, but thank you very much for your time; you're a great person!

I am using Godot 4.1.2 with C# support
When exporting as binary I still cannot seem to use the .skel file in Godot editor.

Lick I tried to reproduce the problem but unfortunately was not able to see the error. Are you encountering this problem on Windows or Mac?

Lick

Misaki
Hello Thanks for the response!
I am on Windows 10. I think it may have to do with my Spine version...
What is the minimum Spine version that is compatible with the Godot runtime?

Misaki

Lick spine-godot works with data exported from Spine 4.1.xx, so it cannot be imported if your data was exported with a version prior to 4.1. For your information, the data I tried was exported from Spine 4.1.23 (and I did not get the error).

Misaki
Gotcha thank you!

I've been having a similar problem and was trying to diagnosis it using this thread: https://esotericsoftware.com/forum/d/24751-spine-godot-c-support/19 only to realize it wasn't addressing this problem but just that stuff wouldn't work after importing in general, here the example projects seem to run fine despite this error so maybe it's ignorable for now? Running windows 10 with spine version 4.1.23, with premultiply alpha disabled on exporting, tried running godot on different drives too.
