Overview

Imports the objects from an Alembic scene archive (.abc) file into the object level.

File name

Path to the Alembic archive (.abc) file.

Filter options

Scene Mode

Whether to import Alembic as a full object hierarchy or whether to load geometry into a single SOP node.

Object Path

A path to one or more objects inside the archive. If specified, the node will load only these object and their children. The default is blank, which means load all the geometry in the archive.

Start Frame

The Alembic first frame at which to sample the geometry. The first frame is imported into frame 1 of Houdini. The next sampled frame is imported into frame 2, etc.

Frames per second

Combined with the Frame parameter, this is used to convert Alembic’s time-based animation to Houdini frames. The default is $FPS (Houdini’s current frames-per-second setting). If the archive file was created with a different FPS, you will need to enter it here.

Load As

How to load the Alembic geometry into Houdini:

Alembic Delayed Load Primitives

These custom primitives are very light-weight and will display faster in the viewport. They are not as full featured as other Houdini primitive types (i.e. ray-tracing is not very accurate), but can be converted to other primitive types if need be.

Unpack Alembic Delayed Load Primitives

Load the geometry as Alembic packed primitives and then automatically unpack the geometry to create native Houdini geometry.

Load Houdini Geometry

Convert the Alembic primitives to use native Houdini geometry.

Houdini Point Cloud

Load the P attribute from the Alembic primitives as a Houdini point cloud. Currently, this doesn’t load any attributes other than P.

Bounding Boxes

Load only the bounding boxes of the Alembic primitives.
