Transform Cache Constraint 变换缓存约束

The Transform Cache Constraint is used to stream animations from Alembic or USD made at the transformation matrix level (for example rigid bodies, or camera movements).

When importing an Alembic or USD file, Transform Cache constraints are automatically added to objects with animated transforms. For time-varying meshes (so deforming animations), the Mesh Sequence Cache modifier is used.

Transform Cache Constraint.

缓存文件

Data-block menu to select the Alembic or USD file.

文件路径

Path to the Alembic or USD file.

序列

缓存是否在一系列文件中分离。

覆盖帧

是否要使用自定义帧用于查找在缓存文件中的数据,而不是使用当前的场景帧。

数值是用于查找缓存文件中的数据或确定在文件序列中使用哪些数据的时间。

帧偏移

从当前帧中减去,用于查找缓存文件中的数据,或确定在文件序列中使用哪个文件

手动缩放

遵从世界原点放大或缩小物体值。

密度属性

The name of the Alembic attribute used for generating motion blur data; by default, this is .velocities which is standard for most Alembic files.

Note

The Velocity Attribute option is currently for Alembic files only.

速度单位

Defines how the velocity vectors are interpreted with regard to time.

  • 帧/框

    The velocity unit was encoded in frames and does not need to be scaled by scene FPS.

    第二

    The velocity unit was encoded in seconds and needs to be scaled by the scene FPS (1 / FPS).

Note

The Velocity Unit option is currently for Alembic files only.

物体路径

The path to the Alembic or USD object inside the archive or stage.

影响

Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
