fix If you do not find any messages in Inspector or Console, please send us a minimal Unity project via email so that we can reproduce the problem: contact@esotericsoftware.com

fix Thank you for sending your prefab! Could you tell us what versions of Unity and the spine-unity runtime you are using?

fix Thank you, but please tell us the spine-unity runtime version too. As far as I have tried with spine-unity 3.8 2021-11-10, your skeletons can be displayed fine with the SkeletonGraphic component.

fix Thank you for the information! I created a new Unity project with Unity 2020.3.38 f1, installed spine-unity 3.8 2021-11-10 and instantiated the prefab you sent us in the scene, but I still could not see the problem as you first reported. I have sent you via email the Unity project I created, so please check and let me know if your animation looks correct.
