Thanks a lot!!! it's fixed!
Do you know why this happens ? the arms looks weird even the same export works great in ue4 and i had more than one spine works perfectly in godot but this no!

Impossible to tell what's going on just from the screenshot. Please provide us with the exported skeleton and atlas files at a minimum. If this only happens when you set a specifc animation, please also provide code to reproduce the issue.

Here are the files.
Not with specific animation , it's with any animation and any skin !
Thanks for your help!

Thanks, I've opened an issue here:
EsotericSoftware/spine-runtimes2412

Thanks !

Hello , could you find the issue ?

I have not yet found the issue. The issue on GitHub will be updated once it is resolved, and I'll post in this thread as well.

Thanks!

Sorry for it taking so long. This has now been fixed in all runtimes. It was a bug in IK constraint. Thanks for reporting!

You'll have to wait for new Godot binaries to build. See the builds scheduled here:
EsotericSoftware/spine-runtimesactions/workflows/spine-godot-v4-all.yml

Once these are complete, you can download new binaries from https://esotericsoftware.com/spine-godot

Thank you very much!!
I will wait for this to complete so i can try!
