Hi,
I've got a small problem. Whenever I import an Alembic file into Houdini and export it back to an Alembic file, the Alembic file gets really big. It's 10-30 times bigger than the original file. Any idea why this happens?
Best wishes,
Thomas

I never try to export an imported Alembic back as Alembic but I just did a shot where I need to export an imported FBX file as Alembic and the file size is roughly double the original FBX size.
It is simple boat geometry animation around 348KB for the FBX and the exported Alembic is 822KB.
Hopefully others can chime in about the issue.

Hi,
I found that unchecking “Transform Geometry To World Space” do the trick, but then, all parts are somewhere else. Importing via the Menu File->Import->Alembic creates a net of Alembic nodes (Archive, XForm etc.). At that point, I could use a new Object Merge node inside of a Geo node; then, I could use ROP Alembic to export. Now, it's fine.
Thanks!
Best wishes,
Thomas
