Set Children in Prefab as individual GameObjects

When spawning a Prefab, I'm trying to have each individual GameObject that makes up the Prefab run its own respective scripts. Basically, I want the Prefab to break after spawning; leaving individual game Objects.

I have the GameObjects in the Prefab as children of an Empty. Any suggestions.

enter image description here

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CreateFab : MonoBehaviour
{
    public Transform Spawnpoint;
    public Rigidbody Prefab;

    public void OnClick()
    {
        Rigidbody RigidPrefab;
        RigidPrefab = Instantiate(Prefab, Spawnpoint.position, Spawnpoint.rotation) as Rigidbody;
    }

    public void DetachFromParent()
    {
        // Detaches the transform from its parent.
        transform.parent = null;
    }
}

Cube Script

using UnityEngine;
using UnityEditor;
using System.IO;

public class WallClick : MonoBehaviour
{
    string path;
    public MeshRenderer mRenderer;


    public void OpenExplorer()
    {
        path = EditorUtility.OpenFilePanel("Overwrite with png", "", "png");
        GetImage();
    }

    void GetImage()
    {
        if (path != null)
        {
            UpdateImage();
        }
    }

    void UpdateImage()
    {
        byte[] imgByte = File.ReadAllBytes(path);
        Texture2D texture = new Texture2D(2, 2);
        texture.LoadImage(imgByte);

        mRenderer.material.mainTexture = texture;
    }
}

Prefabs are already broken when the game is running. Changes to one spawned prefab do not affect others. If you mean unparenting them in hierarchy, set their transform.parent to null. – Swift
I added 'transform.parent to null' to the spawn script but it didn't allow me to click on each individual cube in the prefab. I'll add the code I tried... – user6411634

If you spawn a prefab, give the spawned item a reference.

var obj = Instantiate(prefabGameobject);

You can then do whatever you like with the spawned object

var script = obj.AddComponent<YourScript>();

And you can then modify the variables of your script and so on. Your prefab will not be touched.

The transform.parent you're using here refers to the transform of the gameobject your CreateFab.cs script is attached to, not the prefab's childrens (smaller cubes).

The correct way would be:

// Instantiate the prefab
RigidBody rigidPrefab = Instantiate(Prefab, Spawnpoint.position, Spawnpoint.rotation) as Rigidbody;

// Detach all children from the parent. Each child refers to the transform of a single cube.
foreach (Transform child in rigidPrefab.transform)
{
    child.parent = null;
}
