Hard Edge Data from Houdini to Maya

There is a simple way to export alembic files with “Maya like” hard edges from Houdini.
This can be really useful when the Houdini like hard-edge calculation is necessary or easier to keep (for example really high poly objects).
Of course, you can use this method in HDAs as well (through Houdini Engine in Maya).

  • Create an Attribute Create node and add two vertex attributes:
    maya_locked_normal (integer, value 1, default 1)
    maya_hard_edge (integer, value 1, default 1)
  • Export the alembic file with the usual ROP Alembic Output node.

Tip: save those settings as a preset. 🙂

That’s all.
Cheers, D
