1/** Example 022 Material Viewer
2
3This example can be used to play around with material settings and watch the results.
4Only the default non-shader materials are used in here.
5
6You have two nodes to make it easier to see which difference your settings will make.
7Additionally you have one lightscenenode and you can set the global ambient values.
