NGUI affacting the 3D model texture

[sherocku]

Hi, I am using NGUI3.6.5.
I found that whenever I use the following code to enable a button that made by a NGUI sprite, the texture of the 3D model in another camera will be affected.

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class testNGUI : MonoBehaviour {
5.         public GameObject       testingSprite_GO;
6.         public UISprite         testingSprite_S;
7.         private bool spriteEnabled = true;
8.         private bool gameObjectEnabled = false;
9.  
10.         void OnGUI(){
11.                 if(GUI.Button(new Rect(100, 350, 100, 50), "Sprite On")){
12.                         testingSprite_S.enabled = !spriteEnabled;
13.                         spriteEnabled = !spriteEnabled;
14.                 }
15.  
16.                 if(GUI.Button(new Rect(100, 400, 100, 50), "GameObject On")){
17.                         testingSprite_GO.SetActive(!gameObjectEnabled);
18.                         gameObjectEnabled = !gameObjectEnabled;
19.                 }
20.         }
21. }

After enabling the button the material/ texture of the 3D model is broken, sometimes will be transparent),
The attachment can see the correct model and bugged model.


And this problem will be happen on iphone
When I build on Android or play on unity editor, the model will not have any problems.

It was troubled.
How can I use NGUI sprite but not affect the 3D model texture? Thanks!

First, you shouldn't mix OnGUI and NGUI. They are completely different systems and are not meant to be used together.

Second -- NGUI doesn't affect 3D models at all. NGUI simply creates geometry that's drawn by Unity, nothing else. I suggest looking at the material and/or shader used by your 3D model.
