The best way to learn the tool is to try it out for yourself.
Panning and rotaing are easy; just click the buton you want and the material updates on
the surface. You can shit+ click on a buton to move or rotate in the opposite direcion.
Changing the scale is nearly as easy, but once you select a scale opion, you need to press the
Apply buton just to the right of the scale. The default scale is 1 , and larger numbers mean
that the material will cover a larger area. The other things you can control on this menu are
the surface's lighing properies, but we'll discuss that in detail when we talk about lighing.
