20. Now, open the Minnaert node properties, and you??™ll see that this node is simply
a shader that allows you to set color, diffuse, and darkening values.
If you compare a diffuse shader in the Node Editor to the typical Surface Editor
diffuse value, you??™ll see that the Node Editor offers you more control. In the basic
Surface Editor, you can set the diffuse value, which tells LightWave how much
light your surface accepts from the scene. That??™s it. But with a Node Editor shader,
you are able to apply a slew of different settings for diffuse, with Minnaert being
just one of them. This same concept applies to the other Shading models??”each is
a simple value in the Surface Editor, but you get a lot more control and variation
using the Node Editor.You should experiment with each of them to see their effects.
21. Set the color for the Minnaert node to orange. Set Diffuse to 100% and Darkening
to 45%, as shown in Figure 11.30 on the next page. Using this shader the way
you??™ve set up here is telling the destination node how the diffuse value for the
surface is rendered.
Figure 11.30 Set a few values to make changes to the Minnaert node.
