There is 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. 🙂
