Alembic Animation Sequence + Build Hierarchy by name --> Maya Error

[joko.diep]

Hello,

 

I encounter major problems when exporting an alembic sequence from houdini 17 to maya 2018.
I traced the problem down to the “build hierarchy from attribute” option combined with rendering frame ranges into an alembic-file.

Attached is a test file, to rebuild/illustrate the problem:

export an alembic file with build hierarchy from attribute “name” ON
—> import in Maya causes crash or empty transform nodes, but the hierarchy would be there

export an alembic file with build hierarchy from attribute “name” OFF
—> import in Maya with animation works fine -  except that I don’t get the correct hierarchy I’m aiming for.

 

Is someone encountering the same behaviour and has a solution for that? Or is it only at my system/setup?

I’m working with Houdini 17.0.352 and Maya 2018.5 

(but it didn’t work in any maya version between 2017 and 2018.5)

 

Any help would be appreciated. Thanks!

Joko
