Cinema 4D ShaderGraph C4D着色器

Introduction

引言

The Shader Graph allows you to create and personalize complex materials inside of Redshift, these materials are composed of Shader Nodes. The Redshift ShaderGraph defines the structure and the processing flow of the shading process.

着色器图允许你在红移中创建和个性化复杂的材质，这些材质由着色器节点组成。Redshift shadgraph 定义着色过程的结构和处理流程。

The ShaderGraph Editor UI

图形编辑器界面

The Shader Graph Editor is broken up into a couple sections, the Node Tree which includes the Material Preview above, the Shader Graph Area, and the Attribute Manager which includes the Parameter Search box above.

着色图形编辑器分为几个部分，包括上面的材质预览的节点树、 Shader Graph Area 和包括上面的参数搜索框的属性管理器。

The Node Tree

节点树

The Node Tree located on the far left, contains all the Redshift Shader Nodes that can be added to our Graph Area. The nodes are organized into Categories depending on the type of node or its functionality.

节点树位于最左边，包含所有红移着色节点，可以添加到我们的图形区域。根据节点的类型或其功能将节点组织成类别。

Categories

类别

There are 8 different Categories of nodes to choose to from that include; Materials, Textures, Utilities, Environment, Lights, Volume, Math, and Color. Nodes inherit the color from their respected Categories once brought into the Graph Area.

有8种不同类型的节点可供选择，包括: 材质、纹理、实用工具、环境、灯光、体积、数学和颜色。节点继承颜色从他们的尊重类别一旦进入图形区域。

Search Box

搜索框

The Search Box allows you to search for specific nodes in the Node Tree for easier navigation.

搜索框允许您搜索节点树中的特定节点，以便于导航。

Material Preview

材料预览

Redshift uses the material preview scenes that are provided with Cinema 4D. Redshift only allows for a single rendering session at any given time, so the material preview will update after any active render has finished or is suspended.

红移使用的材质预览场景与电影4D 提供。红移只允许在任何给定时间的单个渲染会话，所以材质预览将在任何活动渲染完成或暂停后更新。

Graph Area

图形区域

The Graph Area, which is based off of Cinema 4D's Xpresso system, is located in the center of our Shader Graph window. This is where we can drag & drop nodes from our Node Tree to build our shader structures.

图形区域，基于 Cinema 4D 的 Xpresso 系统，位于我们的着色器图形窗口的中心。在这里，我们可以从节点树中拖放节点来构建着色器结构。

Attribute Manager

属性管理器

The Attribute Manager located on the far right, holds an attribute editor, for editing the parameters of nodes currently selected inside the Graph Area. The attribute editor has all the same functions as the C4D built in attribute editor, including setting key frames, takes overrides etc.

属性管理器位于最右边，拥有一个属性编辑器，用于编辑当前在图形区域中选择的节点的参数。属性编辑器具有与 C4D 内置属性编辑器相同的功能，包括设置关键帧、重写等。

Parameter Search

参数搜索

The Parameter Search allows us to search for specific Attributes, in our selected node. To enable the search box click on the magnifying glass icon  located at the top right.

“参数搜索”允许我们在选定的节点中搜索特定的属性。为了启用搜索框，点击右上角的放大镜图标。

The Tools Menu includes a number of options to help you inside of the Shader Graph, described below:

工具菜单包括一些选项，以帮助您在内的着色图，描述如下:

Create Texture Node

创建纹理节点

Opens up your File Explorer and after selecting a texture, Redshift will automatically create a texture node inside our Shader Graph.

打开你的文件资源管理器，选择一个纹理后，红移将自动创建一个纹理节点在我们的着色器图形。

Create Texture Node

创建纹理节点

Connect Node to Output

连接节点到输出

This command will connect the output of the currently selected node to the Surface output. This is useful in conjuction with the IPR, for quickly previewing the output of any shader in the graph

此命令将当前选定节点的输出连接到 Surface 输出。这在 IPR 中很有用，可以快速预览图中任何着色器的输出

Connect Node to Output

连接节点到输出

Connect Node to Viewport

连接 Node 到 Viewport

This command will connect the output of the currently selected node to the Viewport output. This is useful when editing the UVs for a specific texture in the graph.

此命令将当前选定节点的输出连接到 Viewport 输出。 这在为图形中的特定纹理编辑 uv 时非常有用。

Connect Node to Viewport

连接 Node 到 Viewport

Optimize All Nodes  优化所有节点

Resizes nodes and deletes any inputs that don't have any connections.

调整节点大小并删除任何没有任何连接的输入。

Optimize All Nodes

优化所有节点

Colorize Graph   彩色图形

Changes node's Title Color based on its category.

根据类别更改节点的标题颜色。

彩色图形

Options Menu

选项菜单

The Options Menu contains Auto settings that can be turned toggled on/off to help with workflow.

选项菜单包含自动设置，可以打开/关闭，以帮助工作流。

Auto Refresh Preview

自动刷新预览

Redshift will attempt to refresh all materials in your scene whenever you make changes to them.

红移将尝试刷新所有材料在您的场景时，你对他们作出更改。

Auto Request Texture Files

自动请求纹理文件

Whenever a texture node is dragged into the Shader Graph, Redshift will open the File Explorer by default.

无论何时将纹理节点拖动到着色器图形中，默认情况下红移都会打开文件资源管理器。

Auto Optimize Nodes

自动优化节点

Redshift will automatically optimize nodes inside your shader Graph while you work.

红移将自动优化节点内的着色图，而你的工作。
