Mesh Sequence Cache Modifier

The Mesh Sequence Cache modifier loads data from Alembic files. It supports static meshes, but is mostly used to load animated meshes. Despite its name, this modifier also supports curves. It also handles file sequences, as well as meshes and curves with varying topology (like the result of fluid simulations).

When importing an Alembic file, Mesh Sequence Cache modifiers are automatically added to time-varying meshes. For time-varying object transforms (so animation of rotation, location, or scale), the Transform Cache Constraint is used.

Non-Alembic files, like MDD and PC2 files, can be loaded using the Mesh Cache modifier.


Cache File

Data-block menu to select the Alembic file.

File Path
Path to Alembic file.
Is sequence
Whether or not the cache is separated in a series of files.
Override Frame

Whether to use a custom frame for looking up data in the cache file, instead of using the current scene frame.

The time to use for looking up the data in the cache file, or to determine which to use in a file sequence.
Manual Transform Scale
Value by which to enlarge or shrink the object with respect to the world’s origin. (Only applicable through a Transform Cache Constraint.)
Object Path
The path to the Alembic object inside the archive.
Read Data

Type of data to read for a mesh object, respectively: vertices, polygons, UV maps and Vertex Color layers.

Vertices, Faces, UV, Color
