Thanks for the update, very much appreciated. 🙂
Great that you found your workaround; I wonder if a custom build Capsule could help here. Brainstorming here: Placing the light under the Capsule, setting it up for different uses, and adjusting it. Perhaps allow for individual or global adjustments, light group-wise. If you think that would improve your workflow, please let me know, and I will discuss it internally.
My concerns with the dual light setup might not be yours, but Light Groups and Light Project settings need to be kept in sync. Otherwise, there might be a surprise at one point.
The option that tech support mentions is the Preview> Illumination Adjustment slider.
This has zero impact on rendering; it is just a preview.
Enjoy your weekend
