Could you use the default constant shader? You can adjust overall transparency and the alpha does not accumulate when stacked. Not sure that is the best way to express the effect but it sounds somewhat like what you are looking for. The only problem may be that by default the alpha from this cuts through the rendered image.

(LARC-E1A)[LITES] Sent: Friday, August 23, 2013 10:34 AM To: softimage@listproc.autodesk.com Subject: Particle overlap I've got several particle strands which overlap. They are also transparent. When they render the transparency is additive where they overlap. I want to render them as though they were a matte, but still transparent. In other words if I were to render them as 100% opaque white as a pass, then reduce transparency in composite, thats the appearance I want. But I want to do this at render time, not comp. Transparency should not be additive. Is that possible? And I'm trying to avoid doing this as a pass.
