For a candle,
a mid-range sample is also fine. But for something like a glass statue, which is
more intricate, a higher sample would prove more accurate. Testing, of course, is
always recommend.
9. Change the scattering Mode setting from its default, Backwards, to Forward.
Backwards scattering is best for softer-looking surfaces, such as clouds, plastics,
cloth, or skin. The Forward scattering setting is great for glassy or waxy surfaces.
On a simple level, you can set this based on your main light??™s position to the objects:
Forward if the object is lit from the front, and backward if it??™s lit from behind.
10. Ignore the Radiosity check box.
Simply, when this is turned on,
you??™re telling the shader to respond
to your scene??™s global illumination
settings. If there??™s no radiosity in
your scene (and there isn??™t any
in this one), this setting doesn??™t
really matter. Figure 11.41 shows
the panel.
11. Close the Properties panel for the node, then drag the Color output and drop
it into the Diffuse Shading input of the destination node. Figure 11.42 shows
the connection.
Note
The Kappa subsurface scattering shader works best when connected to the destination
node??™s Diffuse Shading input.
