同“ Alembic”

The Alembic object contains links to the Alembic file, which means that any changes made to this file will be assumed by Cinema 4D. Objects can be switched for rendering (e.g., low-poly dummy objects can be replaced by high-poly objects for rendering). The object type must, however, be the same! For example, you cannot switch a Spline object with a mesh.

Alembic 对象包含到 Alembic 文件的链接，这意味着对该文件所做的任何更改将由 Cinema 4D 承担。可以切换对象进行渲染(例如，可以用高多边形对象替换低多边形虚拟对象进行渲染)。但是，对象类型必须是相同的！例如，不能将样条对象与网格切换。

The following elements will be added to the Attribute Manager’s object icons:

下面的元素将添加到属性管理器的对象图标中:

• white ,a’ at left 白色，左边 a: no PSR animation; mesh constant : 没有 PSR 动画; 网格常数
• green ,a’ at left 绿色，左边: no PSR animation; mesh points morph : 没有 PSR 动画; 网格点变形
• red ,a’ at left 红色，左边: no PSR animation; point count on mesh changes : 没有 PSR 动画; 点数取决于网格变化
• white film strip at left 左边的白色胶片: PSR animation; mesh constant : PSR 动画; 网格常数
• green film strip at left 左边的绿色胶片: PSR animation; mesh points morph : PSR 动画; 网格点变形
• red film strip at left 左边的红色胶片: PSR animation; point count on mesh changes : PSR 动画; 点依赖于网格的变化
• red ,x’ at right 红色，x 在右边: no link found (e.g., because the name of the Alembic file or the Object Buffer ID changed). : 没有找到链接(例如，因为 Alembic 文件的名称或对象缓冲区 ID 改变了)

If the Alembic object is made editable (C key), the geometry will remain non-animated in its current animation state.

如果 Alembic 对象是可编辑的(c 键) ，则几何图形在其当前动画状态下将保持非动画状态。

Selection Tag

选择标签

The functions described below will only work correctly as long as the number of points/polygons of the Alembic object are not modified.

只有在不修改 Alembic 对象的点/多边形数量的情况下，下面描述的函数才能正常工作。

Textures

纹理

If Facet Sets (polygon selections) are saved in the Alembic file, these can be used in Cinema 4D by entering the name of the Selection tag listed as a (invisible) tab in the Attribute Manager in the Selection field.

如果 Facet set (多边形选择)保存在 Alembic 文件中，可以在 Selection 字段的 Attribute Manager 中输入 Selection 标签的名称(不可见) ，从而在 Cinema 4D 中使用这些标签。

Creating custom Selection tags for Alembic objects

为 Alembic 对象创建自定义 Selection 标记

Proceed as follows if you want to create custom Selection tags for Alembic objects: Duplicate the respective Alembic object, make it editable (c key), make your selection, save the selection and copy the corresponding Selection tag to the original Alembic object. These custom Selection tags will be evaluated correctly (these can, for example, be used for texturing as described above).

如果您想为 Alembic 对象创建自定义 Selection 标记，请按照以下步骤操作: 复制相应的 Alembic 对象，使其可编辑(c 键) ，进行选择，保存选择并将相应的 Selection 标记复制到原始的 Alembic 对象。这些自定义 Selection 标记将被正确评估(例如，它们可以用于上面描述的纹理处理)。
