Guides and Hair

指南和毛发

To begin with, something you should always keep in mind: Guides are not hair. Where guides are present hair must not necessarily grow. Nevertheless, hair can grow where no guides are present.

首先，有些事情你应该时刻记住: 指南不是毛发。在有向导的地方，毛发不一定要长出来。然而，毛发可以在没有向导的地方生长。

In which areas hair roots can be placed is determined primarily by these three factors:

在哪些区域可以放置毛发根主要取决于以下三个因素:

• An object, Selection tag or vertex map, which can be placed in the 对象、选择标记或顶点映射，可以放置在Link 链接 field of the 字段Guides 指南 tab. 标签

• A texture placed in the 一个纹理放置在Density 密度 field of the 字段Hairs 毛发 tab. 标签

• The 这个Root 根 setting in the 设置在Hairs 毛发 tab. 标签

Hair will grow from the hair roots planted using the above-mentioned methods. The direction in which the hair will grow, as well as its length, will be determined primarily by the guides (of course the hair can also be influenced using the Hair material, but we will get to that later).

毛发会生长从毛发根种植使用上述方法。毛发生长的方向和长度主要取决于向导(当然毛发也会受到毛发材质的影响，不过我们稍后会讲到)。

You can define exactly where guides should grow in the Guides tab. Basically, hair will be interpolated between existing guides, wherever they are placed. Hence, it makes sense to plant guides where the hair should grow (this will, though, occur automatically if you select an object and subsequently select Add Hair).

您可以在“指南”选项卡中确切地定义指南应该增长的位置。基本上，毛发将被插入到现有的向导之间，无论他们是放置。因此，植物指南对于毛发应该生长的地方是有意义的(但是，如果你选择一个对象，然后选择添加毛发，这将会自动发生)。

Guides roughly indicate how the hair lies, i.e., how the hairstyle looks. The density of the guides does not at all reflect the density of the hair!:

指南大致指出了毛发的位置，也就是说，发型看起来如何。导游的密度根本不能反映毛发的密度！:

Guides can be manipulated using the numerous Hair tools.

指南可以操纵使用众多的毛发工具。

How each individual hair is rendered (frizz, bend, kink, etc.) is determined by the rough placement of the guides, as well as the numerous channels available in the Hair material.

如何渲染每个毛发(体积曲，弯曲，扭结等)是由导游的粗略位置，以及众多的渠道可用的毛发材质。

Guides are also essential for hair dynamics: Hair dynamics moves the guides, between which the hair is interpolated (dynamics can also be made to affect individual hairs but this would require considerable processing power).

导向器对于毛发动力学也很重要: 毛发动力学移动导向器，在导向器之间插入毛发(动力学也可以影响单个毛发，但这需要相当大的处理能力)。

Unrooted Guides

无根指南

Guides will basically follow any movement the object makes, onto which they are rooted . Nevertheless, guides can still be unrooted (uprooted):

向导基本上会跟随物体的任何移动，它们就扎根在这些移动上。尽管如此，向导仍然可以不扎根(连根拔起) :

• By using the 通过使用Unroot Guides 非根指南 tool. 工具
• By over-manipulation of hair-covered polygon surfaces, on which guides had already been planted. 通过过度操纵毛发覆盖的多边形表面，其中导游已经种植

Unrooted guides will be depicted with a green circle around the root. Unrooted guides have the following properties:

无根导游将在根部画一个绿色圆圈。无根导游具有以下属性:

• They are no longer attached (rooted) to the surface – they more or less float freely. If individual polygons, or groups thereof, are moved, the hair will not follow (as opposed to moving the entire hair-covered object). 它们不再附着在水面上——它们或多或少地自由浮动。如果移动单个多边形或其中的一组，毛发就不会跟着移动(与移动整个被毛发覆盖的物体相反)

• Unrooted guides will result in a 无根向导将导致concrete 混凝土 hairstyle, i.e., all subsequent changes made to the hair-covered surface will not affect the unrooted guides. Hence, if you have completely finished styling your hair you can unroot the guides and make subsequent changes to the surface on which they grow. After you have finished editing the hair-covered surface, simply use the 发型，也就是说，所有后续的变化，毛发覆盖的表面将不会影响无根导游。因此，如果你已经完全完成了你的毛发造型，你可以取消根导游，并作出后续的变化，表面上，他们生长。编辑完毛发覆盖的表面后，只需使用Set Roots 扎根 tool to replant the guides. Since the surface was changed, though, some guides may jump to a different position when replanted. 重新植入导轨的工具。不过，由于表面发生了变化，一些向导在重新种植时可能会跳到不同的位置

• When in the 当在Roots 根 mode, guide roots, including the entire guide, can be moved using the 模式，导向根，包括整个导向，可以移动使用Move 走开 tool and replanted using the 工具和重新种植使用Set Roots 扎根 tool. 工具

• Guide roots can be moved using dynamics (as well as PLA/XPresso). Simply deactivate the 引导根可以使用动力学移动(以及 PLA/XPresso)Fixed Roots 固定根 option in the 选项Dynamics 动力学 tab. 标签
