Orienting player controller to surface they are standing on using raycast, C#, rigid body controller

I am using a ray cast , and the rotation value of the object hit. This code works for primitives I have tested it on. Yet not for the rigid body ,or basic first person character controllers. When placed on these controllers , I get a stutter if in update,and an updated value for one frame if triggered using a bool. My guess is that the rigid body rotation value is set already and it's trying to implement both behaviors.. I really want to get this behavior in my project ,and I refuse to let this beat me, please help xD
Here is the code I am using

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class orientPlayer : MonoBehaviour {
5.  
6.     GameObject firstRayHit;
7.     GameObject lastHitobject;
8.     //float gravity = -9.8f;
9.  
10.     void Awake()
11.     {
12.         RaycastHit hitInfo;
13.         if (Physics.Raycast(transform.position, -Vector3.up, out hitInfo))
14.         {
15.             firstRayHit = hitInfo.transform.gameObject;
16.             lastHitobject = firstRayHit;
17.         }      
18.     }
19.  
20.    
21.     //returns the gameobject hit by our raycast
22.     private GameObject RayToGround()
23.     {
24.         RaycastHit hitInfo;
25.         GameObject _hitObject;
26.         if (Physics.Raycast(transform.position, -Vector3.up, out hitInfo))
27.         {
28.            
29.             transform.rotation = Quaternion.FromToRotation(Vector3.right, hitInfo.normal);
30.         }
31.         _hitObject = hitInfo.transform.gameObject;
32.         return _hitObject.transform.gameObject;
33.     }
34.  
35.    
36.     //orient the player towards the sruface they are standing on . uses the returned gameObject from RayToGround
37.     [ContextMenu("Orient that playaaa")] //This is awesome, lets you right click the componant in the inspector and execute this function =D
38.     void OrientToGround()
39.     {
40.        
41.         if (RayToGround() != lastHitobject)
42.         {
43.             transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y, RayToGround().transform.rotation.z, transform.rotation.w);
44.            
45.             lastHitobject =RayToGround();
46.             RayToGround();
47.            
48.             Debug.Log("OrientingPlayer");
49.  
50.  
51.         }
52.     }
53.  
54.     void FixedUpdate () {
55.         Debug.Log(RayToGround().gameObject.name);
56.         OrientToGround();
57.     }
58. }
59.  

 

Yes, if you have a Rigidbody, you should not be setting the transform.rotation directly. Try setting the rigidbody's rotation instead.

 

I tried using get component rigid body but still nothing
