Can anyone confirm whether or not that the latest DS (as of this writing 4.24) supports invisible emissives (ghost lights) as supported in DS version 4.16.0.3 or earlier? For example, in 4.16.0.3, if I set emissive Cutout Opacity=0.000001, then I get transparent geometry that still emits the same as it I set the opacity to 1.0. I use this type of invisible emissive on virtually all of my renders and I have been very reluctant to upgrade DS for two reasons: 1. I don't want residual shadows from emissives plusI don't want reflective surfaces to reflect the geometry, 2. I hope to re-use my existing project files (they go back to the first days of Iray in DS) seamlessly with the current version of DS.
Thanks for any information you can provide.
