Thanks for the report, I'll take a look.

At a glance, it looks like the issue is that the origin bone is being set to the bone rest position rather than the bone's current pose, which is why its in the correct position but is not moving when animated. That's my guess as to what is going on. I'll take a look once I have the time and see if I can get a PR that fixes the issue.

@TwistedTwigleg
I have a bad news, the new PR don't fix this issue, and I have reimported the animation model from blender to make sure it's not caused by the file itself, but didn't work, the issue still appeared.

then I disabled AnimationTree's active and using AnimationPlayer to check what's going on, see the below sceenshots

3.2.4 rc4

3.3 rc6

That fix was merged after 3.3 RC 6 was built, it's not included in the release. You can test the latest artifacts from the 3.x however: https://github.com/godotengine/godot/runs/2147580417
