Hello. I have a simple 694-frame animation I created in Blender and exported as an Alembic file to Houdini for VFX. I've tried importing to the stage with the Alembic Scene option, and I've tried creating an Alembic node inside a Geo node, and navigating to the .abc file, but once in Houdini, they don't move. What am I missing? Can anyone help?

There should be nothing special you need to do. The easiest way to get an Alembic file into LOPs is with a Sublayer or Reference LOP pointed at the alembic file. This definitely will just load the animated data. But also going through SOPs is something that other users have definitely done successfully. I don't think there is any trick to it. If you can post a simple alembic file or submit one to SideFX support maybe we can help figure out what's going wrong.

One thought: make sure that your Houdini frame range matches the frame range of the data in the Alembic file. Maybe on the playbar you just haven't reached the "animated" time range in your file?
