Billboard particles with arnold renderer?

How do I make billboarded particles with the Arnold renderer?

I've typically done this with scanline using Shape-facing with a camera, and a dynamic material with a simple radial gradient opacity map, which works fine. I've attached a scene using that with simple grey blobs.

I'm not having much luck doing that with the Arnold renderer, I cannot get the edges of the square billboard to be transparent.

What are you using for your material? In general if you're using Arnold as the renderer I would use an Arnold material like a Arnold Standard Surface. Use the Cutout attribute for the transparency. I changed the background to red for clarity.
