VSL Wizards
The easiest way to create new kinds of VSL materials is to use VSL wizards.
These wizards are available in the VSL editor. Wizards construct the necessary
material structure automatically, and insert suitable controls for easy use.
For example, to create a marble like material using wizards:
1. Switch to the material tab of the select window and create a new VSL material using the select window's popup menu.

Create a new material from the select window's material tab.
2. Double click the created blank material icon to open the property window.
Check the 'Preview' option so that you can preview the material while the construction proceeds.

3. Select 'Texture map' from the wizard list and press the 'Add' button. New controls appear below the wizard list.

4. Check the TileX and TileY options, and click browse to find a suitable texture map file. For example, textures/marble.

Define texture map properties
5. Select 'Specular Color' from the wizard list, and press Add. New controls appear.
6. Adjust specular sharpness and brightness until the material looks suitable on the preview window.

NOTE: All wizards are editable - to change a color texture wizard is simply
a case of changing the outputs; To change the 'texture wizard' for example,
to a fade map, change the output from Color to Fade. The wizards are supplied
to make creating materials easier and as a base to work upon.
