Vertex Color Tag

顶点颜色标签

You’re already familiar with the Vertex Map tag that can save weighting (0 - 100%) per polygon point. The Vertex Color tag works similarly and can do much more. It can save, display and even render - with the help of the Vertex Map shader - one or more colors and alpha values per geometry point.

您已经熟悉的顶点映射标签，可以保存加权(0-100%)每多边形点。顶点颜色标签工作相似，可以做得更多。它可以保存，显示，甚至渲染的帮助下，顶点地图着色-一个或多个颜色和阿尔法值每几何点。

It can also be controlled using Fields, i.e., you can create simple parametric texture effects using Fields (if only via the colored object points):

它也可以控制使用字段，也就是说，你可以创建简单的参数化纹理效果使用字段(如果只通过彩色对象点) :

Vertex colors can be saved by numerous foreign formats and Cinema 4D can now also import and export these (e.g., via the Alembic, FBX or Houdini Asset formats). The XPresso Vertex Color node can read out and set colors.

顶点颜色可以保存多种外国格式和C4D 现在也可以导入和导出这些(如，通过 Alembic，FBX 或胡迪尼资产格式)。XPresso 顶点颜色节点可以读出和设置颜色。

What are some uses for vertex colors?

顶点颜色有什么用途？

Objects can be painted directly without worrying about materials and projections 物体可以直接绘制而不用担心材质和投影
This is a standard feature in the gaming industry 这是游戏行业的一个标准特性
Many 3D scanners save scanned colors as geometry points 许多三维扫描仪将扫描的颜色保存为几何点
Various types of information can be coded into vertex colors that can in turn be read by other applications (or vice-versa) 各种类型的信息可以编码成顶点颜色，这些顶点颜色可以被其他应用程序读取(反之亦然)

A polygon object can be painted by calling up the Paint Tool (main menu: Character) and setting the Paint Mode to Vertex Color (RGB). While painting, a Vertex Color tag will be created in which the colors will be saved. A double-click on the tag will call up the Paint Tool directly.

一个多边形对象可以通过调用画图工具(主菜单: 字符)和设置画图模式为顶点颜色(RGB)。绘制时，将创建一个顶点颜色标记，其中的颜色将被保存。双击标签将直接调用画图工具。

Note that the Vertex Color tag will be displayed with a different icon, depending on the mode selected (left: Polygon Points; right Points Only):

注意顶点颜色标签将显示一个不同的图标，取决于选择的模式(左: 多边形点; 右:

As with the Vertex Map tag, the colors of the just selected Vertex Color tag (multiple colors per object are possible) will be displayed in the Viewport.

与 Vertex Map 标签一样，刚刚选中的 Vertex Color 标签的颜色(每个对象可能有多种颜色)将显示在 Viewport。

The values can be displayed numerically and modified in the Structure Manager in Vertex Color mode.

这些值可以在顶点颜色模式下的构造管理器中以数字形式显示和修改。

Restriction: When using Deformers (e.g., Polygon Reduction), the topology of an object to which a Vertex Color tag is assigned will change but the vertex colors will not automatically be adjusted.

限制: 当使用变形(例如，多边形缩减)时，被赋予顶点颜色标签的对象的拓扑结构会发生变化，但是顶点颜色不会自动调整。
