I’m using Raycasting to pickup a weapon on button click. When I do the weapon is parented to the RightHand bone but when I move the weapon doesn’t move with me. Not sure what I’m doing wrong.

 using UnityEngine;
using System.Collections;
using NN.UMAScripts;

public class HoldWeapons : MonoBehaviour {

	public GameObject weaponToHold;
	public GameObject hand;
	public GameObject body;

	// Use this for initialization
	void Start () {
        hand = GameObject.Find("RightHand");
        body = GameObject.Find("MyPlayer");
	}
	
	// Update is called once per frame
	void Update () {
        PickupWeapon();
	}

    void PickupWeapon()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        
        RaycastHit hit;
        Debug.DrawRay(ray.origin, ray.direction * 10, Color.red);

        if (Input.GetMouseButtonDown(0))
        {
            if (Physics.Raycast(ray, out hit) == true&&hit.collider.tag=="Pickup.Weapon")
            {
                weaponToHold = hit.collider.gameObject;
                weaponToHold.transform.parent = hand.transform;
                weaponToHold.transform.localPosition = new Vector3(0, 0, 0);
                weaponToHold.transform.rotation = new Quaternion();
                Debug.Log(weaponToHold.name);
            }
        }
    }
}

Next time please try to put some order in your code, it is really difficult to read if it is not well spaced.

You are not parenting it to the hand, is the only thing you are missing. Use transform.parent like this:

public GameObject weaponToHold;
public GameObject hand;
public GameObject body;

// Use this for initialization
void Start () {
    hand = GameObject.Find("RightHand");
    body = GameObject.Find("MyPlayer");
}       
    
// Update is called once per frame
void Update () {
    PickupWeapon();
}

void PickupWeapon()
{
    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        
    RaycastHit hit;
         
    if (Input.GetMouseButtonDown(0))
    {
        if (Physics.Raycast(ray, out hit) == true && hit.collider.tag=="Pickup.Weapon")
        {
            weaponToHold = hit.collider.gameObject;
            weaponToHold.transform.parent = hand.transform;
            Debug.Log(weaponToHold.name);
        }
    }
}
