UE5: keeps crashing. Please help

bbt636

I am using spine for my characters an recently an error keep occurring:

 0]LogClass: Error: IntProperty FSpineEvent::IntValue is not initialized properly. Module:SpinePlugin File:Public/SpineSkeletonAnimationComponent.h
[2024.11.18-14.57.03:539][  0]LogClass: Error: FloatProperty FSpineEvent::FloatValue is not initialized properly. Module:SpinePlugin File:Public/SpineSkeletonAnimationComponent.h
[2024.11.18-14.57.03:539][  0]LogClass: Error: FloatProperty FSpineEvent::Time is not initialized properly. Module:SpinePlugin File:Public/SpineSkeletonAnimationComponent.h

Does anyone know how to solve it?

The errors you're encountering in UE5 with the Spine plugin suggest that certain properties in the SpineSkeletonAnimationComponent are not being initialized correctly. This could be due to a mismatch between the Spine runtime version and the assets or an issue with the plugin itself. To resolve this, ensure that you are using the latest version of the Spine runtime and that your assets are compatible with this version. Additionally, check if there are any updates or patches available for the Spine plugin that might address this initialization issue. If the problem persists, you might need to manually inspect the code in SpineSkeletonAnimationComponent.h to ensure that all properties are properly initialized.

I am using the last plugin from the git and Spine ESS 4.2.37. Inscpecting the code means going into visual, right? I ask because I am not a programmer but I will try looking into it.

bbt636 Could you please tell us what operations you are performing before the crash occurs? Perhaps from your description, the installation of the spine-ue runtime and the import of the skeleton data is going well, but the crash occurs while you are doing something with the skeleton. Am I right? To what extent can operations be successfully performed, e.g. can a skeleton be successfully instantiated in a level?

In fact I have no major problem, the characters animations run well, every character appears fine, is like a time thing, after some time in the game it just crashes and shows that error as the cause.

bbt636 I understand your situation. Unfortunately, the steps to reproduce the issue are currently unclear, making it difficult to investigate further without a reproduction project. Could you prepare a minimal Unreal Engine project where the problem can be reliably reproduced and email it to us?: contact@esotericsoftware.com
Please include the URL of this forum thread in the email so we know the context. Then we can take a look at what's wrong.

The crash report says :
UnrealEditor_SpinePlugin!UTrackEntry::BeginDestroy() [G:\Archive\PersonalProjects\RankerAcademy\Rankers\Rankers\Plugins\SpinePlugin\Source\SpinePlugin\Private\SpineSkeletonAnimationComponent.cpp:87]

This is the log, I have to add that I am not a programmer so any help is greatly appreciated.

I went through the log, and while it does mention the incorrectly initializede FSpineEvent structs, it doesn't give me a stack trace for the crash which would allow me to understand what is happening.

Is there any way you could share your project either here or privately via email (contact@esotericsoftware.com) with steps to reproduce the issue?

bbt636

Ok, I will record a short video and send the project to contact@esotericsoftware.com

bbt636 Thank you for sending the video and project files! We were able to reproduce the crash and will investigate the cause of the problem. As soon as we find out anything, we will let you know in this thread.
