HDF5 - future plans ?

[Nicholas Yue]

Hi,

  Will HDF5 variant of Alembic continue to be supported or is there some sunset date and transition to Ogawa only ?

Cheers

[Lucas Miller]

Good question!

I would love to drop it in a future version, currently it's an
optional dependency.

Who is still using it?

You know karma has it where as soon as you remove it someone will ask you to restore a 10-year-old Alembic file using hdf5 and will complain that Maya can't read it.  That's why we still compile support for it though we don't use it 95% of the time.

We're still using it at Isotropix for Clarisse, to be able to import legacy HDF5 files and to ship abcconvert so that users can convert their files to Ogawa. However, on export, we use exclusively the Ogawa format.

We could drop HDF5 support completely, but then the users are on their own to get abcconvert binary with HDF5 support, or use another conversion tool.

Blender used to have a disabled-by-default build-time option to enable HDF5 support. It was removed entirely on Jun 15 2020.
