Problems with animation of a glb scene

Asolix

TL;DR The animation of an object works in my test scene but not in the project. Same GLB file, same code used to load the GLB file externally. Video, YT (1:41)

So I have a test scene in which all animations work as they should and a project where the bones are not animated. However, the object is moving. See video. In both scenes the same code is used to load the same file. The code corresponds to that in the documentation.
The glb file is outside the project and is therefore not imported.

At the beginning of the video is the test scene in which the idele1 animation is started in the Ready event. Incidentally, this is currently the only animation with a loop. Then I start the project in which the same file is loaded in a level editor. However, the bones are not animated. Only the root node automatically assigned to the AnimationPlayer moves. The turn animation shown in the video is only a 30° animation.

The AnimationPlayer plays the animation. The value in current_animation_position changes.
I have tried many things, but nothing fixes this. For example, I have tried several different 3d files. All converted to a glb file in Blender. Tested with objects that have only one animation, tested with objects from different sources. I created a few elements myself in Blender and animated them with a few bones. By the way, this is the only file that works! It also works in the project.
I don't know enough about Blender and animations, but I think in the other files just the bones and animations are more complex.
Consider all files work in the test scene with the same code for loading but in the project only my created 3d object works (which by the way only consists of two bones 😃)

Maybe someone can point me in the right direction where the error may lie.

Thanks for reading.

Am I correct in understanding that you don't want to pre-import models into the game, but are trying to do it as you play, perhaps to add new models over time?

It's hard to say without seeing the models and the project, but one possible reason is the unnecessary complexity of the animation, since your simple animation works. And there are animation issues in the new build.

Yes, this is a level editor. The assets and Lua scripts are packaged in a *.pck file, which can then be loaded as the actual game. Everything works wonderfully. Only the animations do not work as expected. Neither in the level editor, nor in the actual game, nor in an exported Godot project.
I have tested several versions of Godot. Back to 4.1.1.

I would say my Blender workflow is simply faulty, because I really have little knowledge here. But all 3D objects work in this test scene where these objects are also loaded from an external source.

I'm extremely interested in this, as I'm going to use a similar approach in my project. I would be very interested to follow your work and how you solve the problem.

I have tested several versions of Godot. Back to 4.1.1.

If reverting to the old Godot version solves the problem, we can expect to see it fixed in future releases.

You could try to do this not in Mono, but in a regular GDScript version. At least just the animation import. And see how it will work.

Asolix

It does not, in version 4.1.1 the animations are not played either. I don't think it's a Godot issue.

The animation works with all tested objects in my test scene. This test scene is also in C# and this test scene also contains the code from the documentation for loading the file, as in my project. Something in my project seems to influence the AnimationPlayer. But unfortunately I have no idea what.
As shown in the video, the scene runs in a SubViewport. But I have already tested that as well.
Here is the code from both scenes:

@Tomcat It is currently only a proof-of-concept project. But once the beetle is crawling, I might post a project overview with a few implementation descriptions.

Same code, my ass. Sometimes it's good to get some distance, do something else and come back later to analyze the error.
In fact, line
sceneNode = (Node3D)gLTFDocument.GenerateScene(gLTFState, 0);
cannot end well. Where the hell did the zero come from? 🤨
