Can I ask here about the relationship between redshift render and alembic file?
The alembic made by Houdini is due to the lack of velocity in Maya's redshift.

I created alembic files in Houdini and then rendered them in maya's redshift.
However, motionblur was not rendered anymore.

I'm definitely checking vel and motionblur (also rename attribute ‘vel’),
but I don't know if redshift does not recognize it, or not included in alembic.
