Solaris: Render Curves as Thick with Arnold?

In the traditional way I would render curves in Arnold, I would select the Geo node containing my curves and go to Arnold -> Shapes -> Curves -> Mode and set it to Thick.

In Solaris, I used a Sop Import to browse the Geo Node (with the thick setting) but when I render, It looks like Ribbons (instead of Thick). Any idea how to solve this?

The arnold-usd codebase has a unit test with this in it:

string primvars:arnold:mode = "thick" (interpolation = "constant")

SOP Import won't pull anything from the Geo node, but you can add this primvar in either SOPs or LOPs and hopefully you'll get what you're after.

Hi robp_sidefx!

Thanks for the reply. Today, I found out about the Render Geometry Settings node that has an arnold tab. There, I can change the Mode to Thick. I still have to test it out but it looks like the easy answer.
