.glb animation differs between Advanced Import Settings and AnimationPlayer

Godot Version

4.6.2.stable.mono

Question

I am having a disparity between the preview of an animation in the Advanced Import Settings and how it moves in the animation player.

The animation is a 4s breathing_additive. During the advanced import settings preview it is perfectly smooth. When playing in the animation player it has a deadzone from 1.9333 to 2.2s which causes the animation to just do a linear motion over that zone. The animation was baked at every frame at 30fps in UE5, and it runs smoothly in Blender/UE5/Godot_advanced_import_preview, so the issue definitely lies with the import as far as I can tell. Is it possible that my bonemap is missing elements that are not printing to my skeletal mesh?

Setting remove_immutable = false during import does not remove the deadzone

Try disabling the animation optimizer. The option is in the AnimationPlayer node in the advanced import settings window.

That did it. Thank you very much; very grateful for the help
