Additive blending for particles in Arnold

Hi all,

Houdini 18.0.391 Arnold: 5.1.1

Is there any way to render particles where each particle's color is adding to the one in front / behind? Ideally there would be no occlusion and dense areas would be much brighter than less dense areas. Opacity at 0 seems to produce no emission and transparency + emission still seems to be occluding particles behind. Please let me know if anyone knows a good solution!

Best,
Hunter
