GLTF import has missing mesh in animations

Godot Version




I am importing a GLTF model I found on sketchfab FPS_Model and when importing, all meshes load correctly however, when viewing the attached animations, the arms of the fps animations do not seem to show up in the animations in the animation player.

While looking around at tutorials, others have not encountered this issue so I remained puzzled as to why this might be happening.

Would appreciate any insight into why this might be happening. Thanks in advance.
