Particles (HY_Foam01_00000.abc - HY_Foam01_00031.abc) seem to be imported correctly - and are animating on my side?
Are you sure you have checked Is Sequence in the Import Alembic options?

Not sure about the mesh part, this seems to be written in .bdc format which is not something blender can import afaik (see here )

note though that I do get messages like this:

BLI_assert failed: /lichtwerk/01_projects/0000_HACK_BlenderSourceDevelopment/HACK_Produktion/11_Git/blender/source/blender/alembic/intern/abc_object.cc:301, xform(), at 'false'
AbcObjectReader::xform(): unable to find IXform for Alembic object '/particles'

It seems that the bdc file will be output to a separate folder after putting this check in the screen shot.
How about thinking it is irrelevant to this case?

I checked "Is Sequence" and loaded it.

@hisai: maybe I am missing the obvious, but the provided zip only contains the foam/particles (HY_Foam01_00000.abc - HY_Foam01_00031.abc)? Where is the mesh part?

OK, can confirm both issues

  • when importing meshes, then particles --> both are visible, but meshes dont animate anymore
  • when importing particles, then meshes --> only particles are visible

@dr.sybren : mind having a look?

Please update the description of the issue so that it's complete, example files and all. That saves people (like me) from having to read through all the comments and from figuring out which files are relevant.
