Multi-Pass

多通道

Here you will find several settings with which you can output individual layers of complex Reflection channels. The settings described below are available for reflection and specular highlights.

在这里，您将找到一些设置，您可以输出复杂反射通道的单个层。下面描述的设置可用于反射和高光。

Separate Materials

单独的材质

You can select from:

你可以从以下选择:

• None 没有: All reflections/specular highlights in the Project will be output to a single Multi-Pass layer without additional separation. : 项目中的所有反射/镜面高光将输出到一个单一的多通道层，不需要额外的分离
• Selected 精选: Only materials whose : 只有其他材质Separate Pass 独立通行证 option ( 方案(Reflectance 反射率 channel’s Layers tab) is enabled will be output separately. 通道的图层标签)将被单独输出
• All 所有: Each reflective material will be output separately. 每种反光材质将分别输出

Separate Layers

分层

If you also want to split individual Reflectance layers in addition to the material splitting, you have the following settings from which to choose:

如果你还想在材质分割的同时分割单个的反射层，你可以从下面的设置中选择:

• None 没有: All Reflectance layers will be summarized. : 将总结所有反射层
• Selected 精选: Only Reflectance channels whose : 只有反射通道Separate Pass 独立通行证 option ( 方案(Reflectance 反射率 channel’s Layers tab) is enabled will be output separately. 通道的图层标签)将被单独输出
• All 所有: Each Reflectance layer will be output separately. : 每个反射层将分别输出

Mode

模式

Here you can define the degree to which reflections should be broken down per Reflectance layer (e.g., specular highlights have an analog behavior for reflections):

这里你可以定义每个反射层的反射应该被分解的程度(例如，镜面高光对于反射有一个类似的行为) :

The reflective object at the bottom left with 2 reflective layers named ,Clearcoat’ and ,Metallic’, respectively, and the Multi-Pass layers in Photoshop. 左下角的反射对象有两个反射图层，分别命名为 Clearcoat 和 metal’ ，以及 Photoshop 中的 Multi-Pass 图层

Note the special case for the example on the right (Channel 3):

注意右边例子的特殊情况(第3频道) :

In addition to the Reflection layer (all reflections combined) there is also 3 layers in the Reflection_Mat_1 folder. If this folder is made visible by clicking on the eye icon the Copper_combined layer - and only this layer - will be made visible. Why? Because this layer is made up of the Copper_Multiply and Copper_Reflection_Base layers. If the remaining two layers in this folder were made visible you would effectively have two active reflections.

除了反射层(所有的反射结合在一起) ，还有3层在反射 _ mat_1文件夹中。如果这个文件夹是可见的，通过点击眼睛图标的 Copper _ 组合层-只有这一层-将可见。为什么？因为这层是由铜叠层和铜反射基层组成的。如果这个文件夹中剩下的两个图层可见，你将有效地有两个活跃的反射。

Also note that, for internal reasons, the sum of the layers will never represent the composited image exactly.

还要注意，由于内部原因，这些层的总和永远不会准确地表示合成的图像。

The same applies in principle for the Multi-Pass specular highlight.

同样的原则也适用于多通道镜面高光。
