Cloud 云Basic 基础Coord.Object 对象
Object Properties
对象属性
If this option is active, a Cloud Group object will not affect this cloud, and the cloud’s settings can be changed individually.
如果此选项处于活动状态，则 Cloud Group 对象不会影响此云，并且可以单独更改云的设置。
混合[0. . 100% ]
When clouds are painted (and thereby newly created), the Mix value is randomly set to a value between 0% and 100%. This value determines where this particular cloud will lie within the defined parameters (Altitude, Luminance Falloff, Transparency Falloff, Color) of the parent Cloud Group.
当云彩被绘制(因此是新创建的)时，混合值被随机设置为0% 到100% 之间。这个值决定了这个特定的云将位于父云组定义的参数(高度、亮度衰减、透明衰减、颜色)中的哪个位置。
If Override Group is activated, Mix will no longer have an effect since the cloud will be independent of the Cloud Group.
如果超驰组被激活，混合将不再有效，因为云将独立于云组。
A cloud’s parent Cloud Group has a Min. Altitude of 5,000m and a Max. Altitude of 10000m. The Mix values below would give the cloud the corresponding altitudes:
云的父云组有一个 Min。海拔5,000米及最高摄氏度。海拔10000米。下面的 Mix 值可以给出相应的云高度:
0% = 5,000m
0% = 5,000 m
50% = 7,500m
50% = 7,500 m
100% = 1,0000m
100% = 1,0000 m
Slight deviations in altitude can result if the 高度上的轻微偏差可能会导致Volumetric 容量 tag’s 标签Adjust Altitude 调整高度 setting is active because this setting places clouds in a manner as to reflect the curvature of the earth. 设置是活跃的，因为这个设置的地方云的方式，以反映地球的曲率高度[0. . + ∞ m ]
This is the height at which a cloud lies. This setting can be changed only here and not interactively in the editor.
这是云层所处的高度。此设置只能在此处更改，而不能在编辑器中交互式地更改。
衰退[0. . + ∞ m ]
Left a lower, right a higher 左一个低，右一个高Falloff 女名女子名 value. 价值
Falloff is a measure, in meters, of a cloud’s density. It determines at which distance an object or background behind a given cloud (with maximum density) will be 50% visible. Low values result in a more dense cloud, higher values result in a more transparent cloud.
衰减是以米为单位测量云密度的一个指标。它确定在给定云后面的物体或背景的距离(最大密度)为50% 可见。低值导致更密集的云，高值导致更透明的云。
亮度衰减[0. . + ∞ m ]
Left a lower, right a higher 左一个低，右一个高Luminance Falloff 亮度衰减 value. 价值
Luminance Falloff regulates the amount of sunlight that is absorbed. The higher the value entered, the less sunlight that will be absorbed and the brighter the cloud will appear. Low values result in clouds being darker, more foreboding on the side opposite the sun. Clouds can be made so dark they look like black smoke.
亮度衰减调节被吸收的阳光量。输入的数值越高，被吸收的阳光就越少，云层就会显得越亮。低云量会导致云层颜色更深，在太阳对面的一侧更具有不祥预兆。云可以变得很黑，看起来像黑烟。
透明度下降[0. . + ∞ m ]
This setting exclusively regulates shadows cast by volumetric clouds onto other clouds or geometry. Higher values make the cloud less opaque, and let it therefore cast a lighter shadow.
这个设置专门调节体积云投射到其他云或几何体上的阴影。更高的值使得云的不透明度更低，因此可以投射出更亮的阴影。
颜色
This setting defines the cloud’s color, usually a simple white or light gray.
这个设置定义了云的颜色，通常是简单的白色或浅灰色。
高品质照明
Activate this option if light sources are located within the cloud that should light it from within. This will increase render times dramatically.
激活这个选项，如果光源位于云内，应该从内部照亮它。这将显著增加渲染时间。
If this option is deactivated, all light sources (that pertain to the volumetric cloud) will be regarded as parallel.
如果此选项被停用，所有的光源(属于体积云)将被认为是平行的。

Use this graph to define the cloud’s density falloff from the outside to its inner.
使用这个图表来定义云的密度从外部到内部的下降。
This function graph, and the 这个函数图，以及Distance 距离 setting below it, will only be activated if an object has been assigned to the cloud, whose shape the cloud is to assume. 设置在它下面，只有当一个对象被分配到云中时才会被激活，云的形状将被假定距离[0. . + ∞ m ]
Distance is the area within which the function graph exercises influence.
距离是功能图发挥作用的范围。
保持身材
This option is only relevant if the object over which a cloud has been placed to give it its form has not been deleted.
这个选项只有在云所在的对象没有被删除的情况下才有用。
If Keep Shape is active, the scene will be opened faster because fewer internal calculations will have to be made to depict the cloud.
如果保持形状是活动的，场景将被打开更快，因为更少的内部计算将必须作出描绘云。
In addition, working in the editor will be faster as well.
另外，在编辑器中工作也会更快。
If you animate the cloud by animating the object that gives it its shape, this option must be deactivated. 如果您通过赋予云形状的对象动画来赋予它动画效果，则必须停用此选项云端类型
Here you will find several cloud types from which to choose, some of which use their own individual calculation methods. You can select from the following types of clouds:
在这里你可以找到几种可供选择的云类型，其中一些使用它们自己的计算方法。你可以从以下类型的云中选择:
标准
Standard cloud that can be edited using the settings described above.
可以使用上述设置进行编辑的标准云。
交流透明层
For more wide ranging clouds through which the atmosphere is slightly visible. Using expansive, flat clouds is recommended.
对于大气层稍微可见的范围更广的云层，建议使用广阔的平面云层。
眼球交叉
For lenticular-shaped, homogeneous clouds. Using flat clouds is recommended.
对于透镜状、均匀的云，建议使用平云。
砧状毛细线虫
For anvil-shaped storm clouds. The cloud should have a relatively vertical orientation.
对于砧状的风暴云，云层应该有一个相对垂直的方向。
Coverage[0..100%]
Contrast[0..100%]
覆盖率[0.100% ]对比度[0.100% ]
These settings are for use in conjunction with the Ac perlucidus cloud types. Coverage defines the actual coverage a cloud exerts, i.e., the greater the value, the more dense the cloud will be. Contrast defines the internal noise contrast which affects the transition of clouds to background.
这些设置用于与 Ac perlucidus 云类型一起使用。覆盖率定义了云的实际覆盖范围，也就是说，价值越大，云的密度就越大。对比度定义了影响云到背景的过渡的内部噪声对比度。
Ratio[0..100%]
Groove Depth[0..+∞%]
Shape Strength[0..100%]
比率[0. . 100% ]槽深[0. . + ∞% ]形状强度[0. . 100% ]
These three settings are for use when creating anvil-shaped storm clouds (i.e. only for use in conjunction with the Cb capillatus incus cloud type. The Ratio setting defines the diameter of the lower cloud region. An axially symmetrical curve will be cut from the cloud (which is actually cube-shaped). Groove Depth defines how smooth or jagged a cloud should be rendered. A value of 0% will result in a smooth cloud. The greater the value, the more the jaggedness will be carried inward (into the cloud) which will reduce the cloud’s overall size. Shape Strength defines the transition between both vertical cloud regions (unaffected upper region / cylindrical lower half). The smaller the value, the smoother the resulting transition will be.
这三个设置是用于创建砧状风暴云(即只用于与 Cb 毛细管云砧状云类型结合使用。比率设置定义了较低的云区域的直径。一条轴向对称的曲线将从云层中切割出来(实际上是立方形的)。凹槽深度定义了云应该呈现的平滑或锯齿状效果。0% 的值会产生一个平滑的云。数值越大，越多的锯齿被带入云中，这将减少云的总体尺寸。形状强度定义了两个垂直云区之间的过渡(未受影响的上部区域/圆柱形下部区域)。值越小，生成的转换就越平滑。

Use the Scale setting to define the noise scale in all three dimensions. If scaled only in a single direction, lamellar cloud formations can be created.
使用比例设置来定义所有三个维度的噪音比例。如果只朝一个方向缩放，就可以形成片状云。
网格点
Grid Points displays a cloud’s expansion in three dimensions. This lets you estimate whether or not a cloud has been modeled correctly. For example, if you intended to model a flat cloud and the middle Grid Point value is very large compared to the other values, you cloud will surely not be flat.
网格点在三维空间中显示云的扩展。这使您可以估计是否正确地建立了云模型。例如，如果您打算为平面云建模，而中间的 Grid Point 值与其他值相比非常大，那么云肯定不会是平面的。
