Abc Points problems Feb. 20, 2019, 11:31 a.m.

So my question is: How is Houdini able to read the data correctly if the alembic library seems to return points where no points exists?

It sounds like the other applications you tried do not respect Alembic's “visible” property. Packed Alembic primitives have an intrinsic called “abcvisibility” you can use to inspect an item's visibility.

The “abcecho” command line tool will report this information. There is currently no convenient way to access the information through the Alembic HOM extensions.

ROP Alembic Partition Mode does not work in 17 Oct. 12, 2018, 1:41 p.m.

The Partition Attribute is only meaningful if you export an Object hierarchy. When exporting from a SOP, the “Build Hierarchy From Attribute” option gives you greater control over where things should be placed in the resulting Alembic archive. Consider enabling “Build Hierarchy From Attribute” and creating a primitive string attribute (identified by the “Path Attribute” parameter) specifying where everything belongs in the resulting Alembic archive.
