# Transform Cache Constraint 变换缓存约束¶

## 选项¶

Transform Cache Constraint.

Cache File 缓存文件

File Path 文件路径

Path to Alembic file.

Sequence

Override Frame 重写帧

The Frame value is the time to use for looking up the data in the cache file, or to determine which to use in a file sequence.

Frame Offset

Subtracted from the current frame to use for looking up the data in the cache file, or to determine which file to use in a file sequence.

Manual Scale

Velocity Attribute

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

Velocity Unit

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

Frame

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

Second

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

Object Path物体路径

Influence

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