Unity Runtime skin Attachment bug

megametx

I don't know how to describe it , but some skin attachment got lost in editor (not all, but some) , Specifically in this cat animation, it supposed to have leg and tail skin attachment to it, some how Unity didnt recognize the skin attachment of leg and tail but the head (which is also a skin attachment)
Tried on unity 6000 and 2022, both have the same issues, and yes , i did mark them with export, and on the texture.png there is sign of leg and tail skin. And i also pick skin as well as press (Reload) on Unity, but no luck
I tried to reproduce but it didnt happen again,

Spine lastest Stable,Runtime 4.2

It seems like you are experiencing an issue where some skin attachments are not appearing in Unity, even though they are marked for export and visible in the texture. This could be related to a mismatch between the Spine Editor version and the spine-unity runtime version, or possibly an issue with the atlas packing settings. Ensure that your spine-unity runtime version matches the version of the Spine Editor you are using. Additionally, check your atlas export settings to ensure they are consistent with your Unity import settings. If the problem persists, consider creating a minimal Unity project that reproduces the issue and send it to contact@esotericsoftware.com for further investigation.

Just to add some context :
-The color space isnt the problem, i tried both 2022 and 6000 with both linear and gamma has the same result

The Shader isnt the problem too, tried with other shader and no luck
No namespace or special character in attachment texture name
-Skeleton Viewer get the same result

Update: Tried to reimport the skel/json file to spine for inspection and found out that the Skin Placeholder is disable ? which seem to disable on its own because I exported with every skin placeholder enable and no warning at all , There might be some export bug right here,

I tried every export setting on the original file and cant get it to export properly, but on new reimport file even with the same export setting as original file, it didnt automatically disable skin placeholder like the original one, pretty sneaky bug right there.

This indeed sounds more like an export issue than a runtimes issue. Could you please send the original problematic Spine project (including the images folder)? You can send it as a zip file to contact@esotericsoftware.com, briefly mentioning this forum thread URL so that we know the context. While a Unity project might help, I'm afraid without the original problematic project we won't be able to identify the cause.

Update #2 : Solved the problem but not the cause
Tried to reimport the skel and export again and somehow it work properly, I tried every export setting on the original file and cant get it to export properly, but on new reimport file even with the same export setting as original file, it didnt automatically disable skin placeholder like the original one, pretty sneaky bug right there. This is the first time i saw this type of bug

megametx I've reviewed the information provided, but it's quite strange. Unfortunately, based solely on what's written here, the cause remains unclear. If the issue recurs, we would greatly appreciate it if you could prepare a minimal Unity project file that reproduces the problem, as explained by Spinebot, and send it to us via email: contact@esotericsoftware.com
We would then be able to investigate it in detail.
