I use the SkeletonGraphic in my UI
Spine version is spine-unity-4.0-2020-10-28-beta

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Spine.Unity;

public class Test : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
        
}

// Update is called once per frame
void Update()
{
    SkeletonGraphic skg;
    skg = GetComponent<SkeletonGraphic>();
    Debug.Log("00000000001");
    Debug.Log(transform.position);
    for (int i = 0, n = skg.Skeleton.Bones.Count; i < n; i++)
    {
        Spine.Bone bone = skg.Skeleton.Bones.Items[i];
        Debug.Log(bone.Data.Name);
        Debug.Log(bone.GetLocalPosition());
        Debug.Log(bone.GetWorldPosition(skg.transform));
    }
}
}

I wonder what is wrong？
thanks！

I also use the spine example Getting Started/6 SkeletonGraphic
SkeletonGraphic (Spineboy) add my script to test

void Update()
    {
        //SkeletonAnimation skg;
        SkeletonGraphic skg;
        skg = GetComponent<SkeletonGraphic>();
        for (int i = 0; i < skg.Skeleton.Bones.Count; i++)
        {

        Spine.Bone bone = skg.Skeleton.Bones.Items[i];

        bone.UpdateWorldTransform();
        Debug.Log(bone.Data.Name);
        Vector3 pos = bone.GetWorldPosition(transform);
        Debug.Log(pos);
    }       
}

the pos is all the same

I want to get the unity world position of the specified name bone.

I create a SkeletonGraphic in UI,the SkeletonGraphic is subobject of a panel.
when the SkeletonGraphic play an animation,I want to get the world postion of the specified name bone.
But I find the world postion of every bone is same.

SkeletonGraphic skg = GetComponent<SkeletonGraphic>();
Spine.Bone bone = skg.Skeleton.FindBone(boneName);
bone.UpdateWorldTransform();
Vector3 pos = bone.GetWorldPosition(skg.transform);

The pos is always the same as the pos of the root bone

I create a Bone Follower Graphic with the specified name bone.
The Bone Follower Graphic is subobject of the SkeletonGraphic .
I can get the right unity postion of the Bone Follower Graphic.

Transform a = transform.Find("Arm");
Debug.Log(a.position);
