Particle Digital Asset not rendering in Arnold (Maya)

[achlucide]

Hello,

I have a particle simulation in Houdini that I exported in a .bgeo sequence and collapsed into a Digital Asset. I import it in Maya using the Houdini Engine plugin, which allows me to load the .bgeo sequence.

After shading, my particles are visible both in the viewport and in the Arnold Render View. Everything looks good.

But when I try to render them using Render Sequence, they disappear.  Same thing for Batch Render.

I've tried looking through all the AOVs, using render layers, but my particles just won't render.

Is there anything I'm doing wrong? Is the problem coming from the way I export my particles in Houdini, or from Arnold itself?

Thanks in advance.
