I've updated our spine-ue4 documentation with sections on upgrading to Unreal Engine 5.3 (or not...) and how to export assets for Unreal Engine 5.3 projects:
https://esotericsoftware.com/spine-ue4#Exporting-for-Unreal-Engine-5.3

Sorry for the inconvenience. The ball is in Epic's park I'm afraid.

Mario I want to suggest simple temporary solution: add in Spine Editor (Desktop app) hint and basic name checking on the export screen.
Maybe Epic really willn't fix that very long time - but you can help Spine user right now. Better than nothing!

How do you install spine plugin inside 5.3 project ? I've done the same process as described, it's so impossible to install it.
Compilation error, again again

Im an animator not dev so sorry if it seem simple, if you have published new way to import asset it's seem you have a working plugin ?

Just tried every solution that i can found.

Have a nice day

valahaha The procedure for installing the Spine plugin in a UE 5.3 project should be the same as it was up to 5.2. Unfortunately, this information is not enough to determine the cause of the problem, so please start a new thread with information about the specific error you are seeing.

Misaki The problem seem already enumerate in this topic without proprer answer.
After following the exact procedure described by esoteric software i cant recompile with the plugins inside my project.
I will glady make a 1 hours long video about my exact problem if needed but only if i have the confirmation that anyone already succesfully installed the plugin inside 5.3.
Im an animator not a dev, i probably cant do much about explaining the exact problem.
I followed exactly all the documention between unreal and esoteric and it didn't compile.

So in UE 5.2.1 the problem about single name for importing seem to apply too.

valahaha At least as far as I have tried so far, our example project (SpineUE4.uproject which is included in the spine-ue4 runtime directory) can be opened with UE 5.3.2 and the skeleton's animation can be played, although the asset name issue described above happens:

So installing the SpinePlugin into a UE 5.3 project itself should be possible.

Could you please start a new thread, as I asked you earlier, and explain in detail the steps you tried?

For those still having trouble installing the runtime to UE5.3 this video has clear step by step instructions. From the instruction video provided by Esoteric I was having problem understanding where to paste the cpp folder for windows. Instructions there are not clear. Hope this helps.

spine-ue works fine with UE +5.3. The only issue is that your .skel/.json and .atlas files must have a different prefix. See https://ungoogled-software.github.io/ungoogled-chromium-binaries/releases/windows/64bit/

Have been having trouble with the Spine Plugin in UE5 as well. I tried UE 5.2.1, 5.5.4, 5.3.2, 5.1.1 all giving similar output log issues in a blank c++ project with no files imported. I included a screenshot of the output errors. Also, tried using 4.2 runtimes and 4.1 just to try to see if that would help.

Are you running UE5 on Windows with MS Visual Studio? What Visual Studio version are you using?

I'm running UE5 on Windows 11 with Visual Studio 2022 Pro.

Misaki Thanks for the reply. As I mentioned to Mario I'm running windows 11 with Visual Studio 2022. As far as steps go I followed the steps outlined in and in https://en.esotericsoftware.com/spine-ue

Also, I'll go ahead and start a new thread as you requested. Thanks.
