云

Contrary to 2D clouds, volumetric clouds are real 3D clouds, intentionally placed, with spatial dimensions. You can actually fly through volumetric clouds.

与二维云相反，体积云是真正的三维云，有意地放置在空间维度上。你实际上可以穿过体积云。

And this is how volumetric clouds are created

这就是体积云是如何形成的

1. If you haven’t already done so, create a sky: 如果你还没有这样做，创建一个天空:Create / Physical Sky / Physical Sky / Create Sky 创建/物理天空/物理天空/创建天空.
   
   
2. Make sure that the 确保Volumetric Clouds 体积云 option is activated in the Sky Manager. 选项在天空管理器中被激活
   
   
3. Select 选择Create / Physical Sky / Cloud Tool 创建/物理天空/云工具. Rotate your editor view so you are looking up at the sky, and paint a cloud formation by clicking with and dragging the left mouse button. Avoid painting your clouds too close to the horizon since they will then be created too large. .旋转你的编辑器视图，这样你就可以仰望天空，并通过点击和拖动鼠标左键绘制一个云的形成。不要把你的云彩画得太靠近地平线，因为那样会造成太大的云彩
   
   
4. If you want to create additional clouds, deselect all Cloud objects or click on the top-most Sky object in the 如果你想创建额外的云，取消选择所有的云对象或者点击顶部的天空对象Object Manager 对象管理器’s hierarchy. 的等级制度
   
   If you want to create a cloud manually, and initially without volume ( 如果您想手动创建一个云，最初不需要体积(Cloud 云), make the Cloud object a child of a Sky object. ) ，使云对象成为天空对象的子对象

Existing volumetric clouds can be checked individually (single object Cloud) or as a group (object Cloud Group).

现有的体积云可以单独检查(单个对象云)或作为一个组(对象云组)。

Cloud Shape

云的形状

If you want to assign a specific shape to your cloud, simply create the shape and make it a child of the Cloud object.

如果您想为您的云分配一个特定的形状，只需创建这个形状并将其作为 Cloud 对象的子对象即可。

You can use primitives, polygon objects, splines, even particles (make emitters or TP geometry objects (Thinking Particles)) a child of the Cloud object.

您可以使用原语、多边形对象、样条、甚至粒子(使发射器或 TP 几何对象(Thinking Particles))成为云对象的子对象。

In fact, all you need to do is: Make the object a child of the cloud, wait until the cloud, or cloud formation, has assumed the object’s shape (the time this takes can vary, depending on size), and delete the object. The cloud will retain the shape of the object.

事实上，你所需要做的就是: 让这个物体成为云的一个孩子，等到云，或者云的形成，已经假定了这个物体的形状(这个过程所需的时间可以根据大小而有所不同) ，然后删除这个物体。云将保持物体的形状。

When moving clouds interactively, they can only be moved horizontally. The altitude of the clouds can be set in the Cloud object’s settings.

当云交互移动时，它们只能水平移动。云的高度可以在云对象的设置中设置。
