PlayableGraph was not destroyed.

[xtc06]

Hi,

Hello, I wrote some code to export, it works very well, but I have the message : PlayableGraph was not destroyed. My code : ExportOptions exportOptions = new ExportOptions(); exportOptions.MergeClipsWithMatchingNames = true; GLTFSceneExporter exporter = new GLTFSceneExporter(gameObject.transform, exportOptions); exporter.SaveGLB(path, fileName);

I can't use using, destroy or dispose for GLTFSceneExporter, am I doing something wrong?

Hey, which version/commit are you on? There's a version/2.x branch with more improvements by now, so would be great if you could test on that and ideally also on latest 1.x, 1f5c1a2d294fe4c618d97bbfac2c8a8a72e33a0c.

That message would mean that something in your export is using humanoid rigs, which is supported, but there were some versions where it produced an error similar to what you've posted.

I added the package from this URL : https://github.com/prefrontalcortex/UnityGLTF.git?path=/UnityGLTF/Assets/UnityGLTF The version : 1.24.0-pre.2

[hybridherbst]

Can you try either https://github.com/prefrontalcortex/UnityGLTF.git?path=/UnityGLTF/Assets/UnityGLTF#release/2.0.3-exp or https://github.com/prefrontalcortex/UnityGLTF.git?path=/UnityGLTF/Assets/UnityGLTF#release/1.24.2-pre?

Thanks I will try :)

[xtc06]

I will test when the repository will be accessible again ^^

[hybridherbst]

Sorry, typo! I meant from the prefrontal cortex fork, I updated the URLs above

I just tested the 2.0.3-exp, the problem persists.

[hybridherbst]

Thank you - then it would be great if you could send me a zipped project (without Library folder etc.) where the error reproduces when exporting a file and some steps. Thanks!

[xtc06]

Yes as soon as I have time I will prepare a file for you. I tested (the 2.0.3-exp) on another scene, with a new script and a new FBX to export, the problem no longer seems to be present, the scene that is causing me problems contains a fbx rigger, content elements in the bones when they are dissable, create error logs during the export, and the meshes have an UNorm8 color format which also poses a problem during the export, I wonder if the problem does not come from that :)

[hybridherbst]

Thanks for the additional info - yes, the issue is most likely from some Animation Rigging combination, that's pretty much the only case where a playable graph is directly sampled on export. So a repro file would be well appreciated!

And if you can open another issue about the UNorm8 issues that would be appreciated too!

[xtc06]

Yes the problem comes from the animations. I'm on unity 2021.3.22f1 URP.

Hey @xtc06 I was finally able to look at your report, however there's not a complete file in the zip - the model is missing bones, so I can't reproduce your issue. Would be great if you could export as .unitypackage so I can reproduce here. Thanks!

[xtc06]

I will do what is necessary when I have a little more time available, unfortunately I have a lot of work at the moment, but I promise to do it as soon as possible :)
