Metal
This shader simulates metallic surfaces. The gradient species the color of the metal. Increase the
Frequency for ner details.
Planet
This shader is effectively four shaders combined in one: Saturn, Saturn’s Ring, Uranus and Neptune.
Choose the desired shader from the Type drop-down list.
Saturn
Because of its fast rotational speed, Saturn has an elliptical shape. For an
accurate representation of the planet, you will need to atten the sphere to
which this shader is applied — its Y-axis should be scaled to about 0.85.
If you mix the Saturn shader with, say, a brown color (50% shader/50% brown
color), you can simulate many rock formations that you can then project onto
a Landscape object.
Simulates the planet Saturn with its typical coloring and cloud structure. The texture is cyclic in the
U direction.
