Alembic curves rendering - segmented ?

[nicholas_yue 0]

I have an alembic file which has curves which I generated (programmatically). The default constructor is to create cubic curves.

However, when render it in Mantra, it looks segmented and not smooth. Is there some special curves setting in Mantra ?

Here is the Alembic file

curves.abc

on the /geo1 object, go to the Render tab/Geometry and turn on "Render Polygon Curves As Subdivision (Mantra)"
