Working with the Node Editor is not as complex as you once thought, is it? Sure, there
are many nodes that you have yet to explore, and you should know that there are many
you might not even use. This next section will show you a few other avenues you can travel
down when working with the Node Editor.
Exercise 11.3 Subsurface Scattering with Nodes
The term subsurface scattering has been tossed around the 3D community for some time,
but it might be a new term to many LightWave 3D users. Put simply, subsurface scattering
is an attribute that gives a surface the illusion of thickness or depth. It is rendered
based on complex calculations, but it has been made easier to control with the addition
of the Node Editor.
A good example is a wax candle: The candle look solid, but toward the top where the flame
is, the light from the flame diffuses through the surface.
