Alembic import/export

[haggi 28]

Hi,

during the work with my maya alembic reader, I discovered a problem with alembic files written by houdini. Obviously Houdini exports an additional point geometry together with my mesh. If I load the alembic in Maya, I get a mesh shape and a particle shape. In houdini I can see two packed objects in the alembic sop. This only happens in certain situations. e.g. if I create a box and deform it, only one packed object is created in the alebic export. Only if I export my flip mesh an additional packed point geometry is exported and I get a warning in the exporter: "Renaming node to /geo1/file3_1 to resolve collision". Does anyone know what's going on here? It seems not to be a new phenomenon, it happens the same way with H16.

never had issues with it. you should check if all data garbage data is removed.  all un-needed point /primitive und specially  details attributes.

You may need to make a simplified example scene to demo the issue. I'm guessing it's specific to your setup.

no answer? I have the same issue: 'Renaming node to /AlLEMBIC/File1_1 to resolve collision

Hard to say without a hipfile.

Unpack the geometries before creating the alembic, and/or create a 'path' attribute and check "build hierarchy from attribute" on the alembic rop.
