Good day,

I have a following problem - using Maya Educational license, I have created a simple house, deleted transforms and history and all, separated different materials into different namespaces, triangulated it and then exported it out as Alembic.

When imported to Non-Commercial version of Houdini, I can load it nice and easy, I can see all the different groups and I can blast them away to separate concrete wood and glass for testing out the rbdMaterialFracture node.

It still works, but some features are just not working as intended - I can't increase the geometry for brush paint, or I can't see the Primary Volume geometry guide. Then I have tried different things and run into more issues - divide doesn't work. Only way to work around that was to convert the whole mesh into VDB and then convert it back to polygons. Since then all the features works well and I had no issue.

But I believe I must be doing something wrong. Not ticking the right option in Maya when exporting to Alembic perhaps? Does anyone have any clue what can be wrong? I am happy to provide the houdini and Maya file if you need that for debugging.

Thank you for any help

Did you unpack and convert to polygon after reading in the alembic? You probably won't be able to interact with the topology without doing so.
