Switching between materials

An interesting interactive option you can provide to clients is choosing between different material finishes. A good example of such a system can be found in Autodesk Showcase at http://www.autodesk.com/products/showcase/overview, which displays a popup list of material thumbnails in a very realistic real-time view of a design.

We follow a similar approach as the camera switcher, by setting up a list of alternative textures and using the OnGUI() method to display a button to switch between alternative materials. It is important to prepare the list of textures on beforehand. This is shown in the following code:

using UnityEngine;
using System.Collections;
public class switchMaterials : MonoBehaviour {
  public Material[] materialList;
  public GameObject target;
  private int index = 0;
  void OnGUI(){
    if (GUI.Button(new Rect(5,5,100,24), "Next Material")){
      index = (index + 1) % materialList.Length;
        target.renderer.material = materialList[index...
