Meta Quest开发：物品拾取缩放Scene View正常但Game View失效问题

我需要实现的功能是：拾取物品时，物品移动到手部的过程中从原始尺寸缩放到约6英寸（对应代码中targetSize = .15f）。目前这个功能在编辑器Scene View中表现正常——物品被拾取后会向手部移动并缩小，但在Game View（头显视角）里完全不符合预期：物品始终保持原尺寸，反而因为靠近视角视觉上显得更大。

开发平台是Meta Quest，缩放脚本ResizeObject继承自XRGrabInteractable，挂载在物品上，由Ray Interactor触发激活。玩家仅支持物理移动，没有其他移动方式。

补充现象：

• 通过鼠标拖动Transform拾取物品时，Scene View和Game View的表现都正常
• 通过Ray Interactor拾取时，只有Scene View正常，Game View中物品不缩放，且Mesh Collider也不会随物品缩放

相关代码实现如下：

public class ResizeObject : XRGrabInteractable
{
    private Vector3 OriginalSize;
    private float BiggestDimention;
    private float OriginalDistance;
    private float TargetScale;
    private Vector3 OriginalPos;
    private Vector3 OriginalRot;
    private Vector3 OriginalScale;

    public bool selected;
    private readonly float targetSize = .15f;
    private Vector3 playerPos;

    // Start is called before the first frame update
    void Start()
    {
        selected = false;

        playerPos = GameObject.FindGameObjectWithTag("Player").transform.position;

        OriginalPos = new Vector3(transform.position.x, transform.position.y, transform.position.z);
        OriginalRot = new Vector3(transform.rotation.x, transform.rotation.y, transform.rotation.z);
        OriginalScale = transform.localScale;

        OriginalSize = gameObject.GetComponent<Collider>().bounds.size;
        BiggestDimention = OriginalSize.x;
        if (OriginalSize.y > BiggestDimention)
            BiggestDimention = OriginalSize.y;
        if (OriginalSize.z > BiggestDimention)
            BiggestDimention = OriginalSize.z;

        TargetScale = targetSize / BiggestDimention;

        OriginalDistance = Vector3.Distance(OriginalPos, playerPos);
    }

    // Update is called once per frame
    void Update()
    {
        if (selected)
        {
            float currentScale = Vector3.Distance(transform.position, playerPos) / OriginalDistance;
            if (currentScale > 1)
                currentScale = 1;
            else if (currentScale < TargetScale)
                currentScale = TargetScale;
            transform.localScale = new Vector3(currentScale,currentScale,currentScale);
        }
    }

    protected override void OnSelectEntered(SelectEnterEventArgs args)
    {
        base.OnSelectEntered(args);
        Debug.Log(gameObject.name + " Select()");
        selected = true;
        transform.localScale = new Vector3(TargetScale,TargetScale,TargetScale);
    }

    protected override void OnSelectExited(SelectExitEventArgs args)
    {
        base.OnSelectExited(args);
        Debug.Log(gameObject.name + " Deselect()");
        selected = false;
        transform.position = OriginalPos;
        transform.eulerAngles = OriginalRot;
        transform.localScale = OriginalScale;
    }
}
