Transform Cache Constraint 变换缓存约束¶
转换缓存约束 用于串流来自 Alembic 的在变换矩阵制作的动画(例如刚体或摄像机运动)。
当 导入Alembic文件 时,变换缓存约束会自动添加到具有动画变换的物体中。对于时变网格(变形动画之类),将使用: 网格缓存序列修改器。
选项¶
- Cache File 缓存文件
要选择的Alembic 文件的数据块菜单。
- File Path 文件路径
Path to Alembic file.
- Sequence
缓存是否在一系列文件中分离。
- Override Frame 重写帧
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。
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
遵从世界原点放大或缩小物体值。
- 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
在档案的Alembic 物体的路径.
- Influence
Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
