Hey! Tried making some curves in Houdini, extruding circles along them and rendering in Octane, but they do not show up

Any tips? I'm fairly new to Houdini so probably a simple fix, just couldn't figure out why they show up in the viewport but not in an Octane render. A basic cube using the same emissive material renders just fine as you can see. Here is my scene file and some screenshots:

Thanks in advance!
