how to control "SMOOTHNESS" via GUI slider?! SOLVED!

hello world

I've been trying to use a GUI slider to control 'smoothness' of an object but It just doesn't work.

here's my latest atempt:

Code (csharp):

1.  
2.   using UnityEngine;
3.   using UnityEngine.UI;  
4.   using System.Collections;
5.    
6.   public class metalicslider : MonoBehaviour {
7.   public GameObject metasphere; // object that will be affected
8.   public Slider sldfind;
9.   Renderer sphrend;
10.      
11.      // Use this for initialization
12.      void Start () {
13.        sphrend = metasphere.GetComponent<Renderer>();
14.        sphrend.material.shader = Shader.Find ("Standard");
15.          
16.          }
17.    
18.         // Update is called once per frame
19.      void Update (){
20.        sphrend.material.EnableKeyword ("_SPECCGLOSSMAP");
21.        sphrend.material.SetFloat ("_SPECCGLOSSMAP", sldfind.value);
22.    
23.      }
24.   }
25.    
26.  

I checked the documentation, tried this one too, but no cookie

Code (csharp):

1.  
2.   using UnityEngine;
3.   using System.Collections;
4.    
5.   public class ExampleClass : MonoBehaviour {
6.   public Renderer rend;
7.   void Start() {
8.   rend = GetComponent<Renderer>();
9.   rend.material.shader = Shader.Find("Specular");
10.   }
11.   void Update() {
12.   float shininess = Mathf.PingPong(Time.time, 1.0F);
13.   rend.material.SetFloat("_Shininess", shininess);
14.   }
15.   }
16.  

please, help!

 

I figured it out!
the name of the property is "_GlossMapScale" that's the one which controls the "Smoothness" slider
