This feature available only on non-connected node,
after it's connected it is no longer available for editing.

Old projects also show this option as non accessible (grayed out)
so I can't export material_ID to Max the way I could.

Houdini engine also can't export material ID
my post in this thread
https://www.sidefx.com/forum/topic/58396/ [www.sidefx.com]
and there's no docs/tutorials about it.

maybe there's a different to export mesh from houdini -> max with mat_IDs

Thanks!

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.

Thank you, Derrick!

that works!

//it kills 3ds Max though (on the last piece of my animation)
it's easy to kill max by almost anything you do

I am also experiencing this bug, and it seems partitioning is the only method currently working with our alembic > Maya pipeline. We reverted to H16.5 for any exports, which still works fine. It seems stuck as grayed out in H17.

if something worked well in the previous version and now it doesnt… it is of course your fault..
more over if the settings are there but always greyed… you might as well removed it…
can u guys pls bring this back as it maximize compatibility ?
