Hi, As a Houdini newbie I hope someone can make a suggestion on getting this to work correctly.
This is what I'm trying to match in Houdini (rendered in Maya with 3delight and some coding to sort out the normals on the curves)


Trying to do this in Houdini I found this tip on using curveNormal.otl https://vimeo.com/65493994. [vimeo.com]
The normals direction update in the scene view when setting the ‘firstupVector’ in the curveNormal but the render results are not working.

heres the setup


Cheers
