Shader Properties
类型
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.
这个着色器实际上是四个着色器组合在一起: 土星，土星的光环，天王星和海王星。从类型下拉列表中选择所需的着色器。
土星
Simulates the planet Saturn with its typical coloring and cloud structure.
模拟土星的典型颜色和云层结构。
The texture is cyclic in the U direction.
纹理在 u 方向是循环的。
Because of its fast rotational speed, Saturn has an elliptical
shape. For an accurate representation of the planet, you will need to flatten the sphere to which this shader
is applied — its Y axis should be scaled to about 0.85. 由于其快速的转速，土星有一个椭圆形状。为了精确地表示行星，你需要将这个着色器所对应的球体平坦化ー它的 y 轴应该缩放到0.85左右
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. 如果你混合土星着色器，说，一个棕色(50% 着色器/50% 棕色) ，你可以模拟许多岩层，然后你可以项目到一个景观对象
土星光环
Simulates the rings around Saturn — the D, C, B, A, F and G rings, with the Cassini and Encke gap. The Saturn’s Ring shader has an alpha channel that you can use within the Material Editor on the Alpha page.
用卡西尼环和恩克环模拟土星环ー d、 c、 b、 a、 f 和 g 环。土星的光环着色器有一个阿尔法通道，你可以在阿尔法页面的材质编辑器中使用。
Saturn is approximately one third as wide as its famous rings. So
that stars shine through between the rings, activate the alpha channel of any material to which this is
applied. You may want to make the rings quite transparent since in reality these rings are huge numbers of
tiny rock and ice particles that allow the light from beyond to shine through. 土星的宽度大约是其著名光环的三分之一。这样星星就可以在光环之间闪耀，激活任何物质的阿尔法通道。你可能想让这些光环变得十分透明，因为实际上这些光环是由大量的微小岩石和冰粒组成的，这些微小的岩石和冰粒允许光线从外面照射进来
乌拉诺斯/海王星
These shaders simulate the planets Uranus and Neptune with their typical coloring and cloud structure.
这些着色器模拟了天王星和海王星的典型着色和云层结构。
