3D Objects Problem

Hi guys. Do you have idea on how to change texture to a 3d objects? My goal is to change the texture2d to a 3d object like image in blender but it has an extension .obj here is my code. Any suggestion will be appreciated.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using System.Text.RegularExpressions;
4. public class test1 : MonoBehaviour {
5.     public static string print = Try.aw;
6.     public GUIStyle B;
7.     public Texture2D A;
8.     public Texture2D C;
9.     bool CorrectValue;
10.     bool a;
11.     void OnGUI() {
12.    
13.         if(GUI.Button (new Rect (100, 100, 40, 40), "", B)) {
14.             if(int.Parse(print) == 1){
15.                 CorrectValue = true;
16.             } else {
17.                 CorrectValue = false;
18.             }
19.             if(int.Parse(print) == 2){
20.                 a = true;
21.             } else {
22.                 a = false;
23.             }
24.         }
25.    
26.         if(CorrectValue) {
27.             GUI.DrawTexture(new Rect(500,200,200,200),A);
28.         }
29.         if(a) {
30.             GUI.DrawTexture(new Rect(300,200,200,200),C);
31.             GUI.DrawTexture(new Rect(200,100,200,200),C);
32.         }
33.     }
34. }

 

do you mean you want the 2d texture to display an image of a 3d object? as if a camera feed was showing the 3d object projected onto the texture?
