### Create a script

```csharp
using UnityEngine;
using MeshAnimation;

/// <summary>
/// Example: drive MeshAnimationInteract.ForceProximityEnter/Exit
/// based on whether any tracked object enters the proximity radius.
/// Attach to the same GameObject as MeshAnimationInteract.
/// </summary>
public class MeshAnimationInteractExample : MonoBehaviour
{
    [Tooltip("Target with MeshAnimationInteract component.")]
    public MeshAnimationInteract target;

    [Header("Proximity")]
    [Tooltip("Objects to watch. Any one of them entering the radius triggers Enter.")]
    public Transform[] trackedObjects;

    [Tooltip("Enter radius (units).")]
    public float enterDistance = 3f;

    [Tooltip("Exit radius. Should be >= enterDistance to avoid flickering.")]
    public float exitDistance = 4f;

    private bool _isInRange;

    private void Update()
    {
        if (target == null) return;

        bool anyInRange = IsAnyTrackedInRange(_isInRange ? exitDistance : enterDistance);

        if (!_isInRange && anyInRange)
        {
            _isInRange = true;
            target.ForceProximityEnter();
        }
        else if (_isInRange && !anyInRange)
        {
            _isInRange = false;
            target.ForceProximityExit();
        }
    }

    private bool IsAnyTrackedInRange(float radius)
    {
        foreach (Transform t in trackedObjects)
        {
            if (t == null) continue;
            if (Vector3.Distance(target.transform.position, t.position) <= radius)
                return true;
        }
        return false;
    }

    private void OnDrawGizmosSelected()
    {
        if (target == null) return;
        Vector3 center = target.transform.position;

        Gizmos.color = new Color(1f, 0.8f, 0.1f, 0.3f);
        Gizmos.DrawWireSphere(center, exitDistance);

        Gizmos.color = new Color(0.4f, 0.92f, 0.55f, 0.5f);
        Gizmos.DrawWireSphere(center, enterDistance);
    }
}
