Arnold not rendering hair that uses a sweep. Renders ok in Physical Render

Hi. I am using c4d hair to generate some tentacles and using a sweep method in the hair simulation to give the tentacles their shape. Im only getting a ribbon of the shape when I render in arnold, but it renders correctly when I render using c4ds physical render. Is this a doable task in arnold? I see I can render a regular sweep along a spline fine so Im not sure why this is not working. Thanks for looking

I found a work around that did the job in the IPR.. But now that Im trying a test render it stopped working in the PictureView. I am generating splines with the hair simulation and sweeping them outside of the hair sim now and that solved the problem I was initially having, but only in the IPR I am realizing. They do not render in the pictureview. Any idea where I am going wrong? I saw a similar thread and added an arnold tag to the hair but that did not solve the issue.

Was your original method using the Sweep type under the Generate tab of the Hair object? Hair instances are not supported (yet), but there's a workaround: move the Hair object under a Connect Object.
