Iray Camera Light

There's a new product (saw it in today's promo email from DAZ) from @KindredArts which looks interesting but ... will it work? The product page says it is compatible with 4.16 but it has Ghost Light attachments which, from what I've read here, will not work in 4.16.
Unusally for @KindredArts, there's no discussion in the PA Commercial Products sub-forum yet so I thought I would ask here as there has already been discussion about Ghost Lights. By the way, I am still on 4.15 and don't intend to update until they have ironed out the wrinkles in the new betas.

Please bear in mind the distinction between the General Release (4.16.0.x using an older version of Iray in which ghost lights are not a problem) and the Public Build (4.16.1.x using the current, more or less, version of Iray, in which ghost lihgts are an issue though there are steps that may be leading to a solution).
Still, it is a bit questionable to release a product when it is already known that it will not work with the latest version of IRay. I mean, IRay is in the product title. That there miight be a solution one day is no guarantee.
I was not aware of the Nvidia changes, i start making these sets months in advance so engine changes don't cross my rader unless there's big tech changes coming. I've contacted daz to see what's going on but as Richard said above, there may well be changes between betas. It's not just light kits that get affected by this, a lot of environments lean on diffuse lights too, and would obviously be broken by the change as well. I already know how i can update my GL sets to reflect these changes but it will be unfortunate if they are broken going forward.
I don't have a copy of 4.16 yet but i'll keep monitoring the issue and see if i need to make corrections. Fingers crossed that daz fixes it on their end.
That's encouraging - especially as I do have your other Ghost Light kits (and use them a lot).
Ok just to follow up on this for anyone who drops in -
There is a workaround for this issue, but again i'm going to hold off modifying any sets until daz have given me a firm answer on whether things will change or not. They may still patch out this issue so i'm not updating sets until i know what their plans are. If this is just the reality of the new iray update, i will work through all of my kits utilizing ghost lights and update them for the store. Also my free tutorial will be updated to reflect the new information obviously.
Thanks
Yes, thank you for your responses.
I also purchased the KinderArts Iray Camera Lights - tried it the first time today (Jan-01-22) and it doesn't seem to do anything. The 'lights' have no impact on the scene, and the cameras show up as those ugly white-black umbrellas regardless of the Ghost setting (although maybe I misunderstand what that means). I was looking for Poser-like light which I could place in a scene to lighten a shaded area and yet NOT be visible in the render. At least with DS 4.16.0.03 Pro, I'm still suffering what seems like a horrible design decision in the DS arhcitecture!
Doesn't anyone know of a non-standard DS light which is invisible in a render? So F* the 'emissive-surface' BS. I want a light which bathes surfaces in light, yet has no visible presence in a render. That seems like a possiblity to my dumb engineering mind.
@coralyn
may I ask why It must be a non-standard DS light? Is it because it appears in mirrors even though being invisible otherwise?
Seeing as the changes have been made by Nvidia, assume that they will be reflected in the next general release as it's on Nvidia for the update/change with ghost lights!
You can easily make your own ghost lights from primatives for free. The method is show in one of the Daz "In the studio" sesions. https://www.daz3d.com/in-the-studio-with-daz-3d the one that you will need is "Sci-fi Interiors, Ghost Lights, & Outfits - In the Studio with Daz 3D." Also from the same page "Lighting, Camera Angles, & Puppeteer - In the Studio with Daz 3D" will tell you how to get the most of the standard Daz lights.
Thank's Matt, I'll check our that tutorial. As for KinderArts, I don't really want my money back - the theory offered by the tool is too enticing. Just hoping it eventually works with what DS calls 'the norm' :-). I should probably try to roll DS back a few revs then BLOCK all of these new magic DS updates. Get something which works and stick to it. I've also cross dForce purchases off my list. To spite my 3000 CUDA cores, dForce simulations virtually never work (always 'explode').
I did finally figure out one oddity in DS - create a new light and it forms as 1-sized pizel, so obviously it doesn't 'emit' enough light to effect the scene! You need manually go in and make bigger, hoping it doesn't block your camera-view. Just a new way of working - defaults are bad & one needs to always manually change. I suppose that's my dForce problem - defaults are unusable & I need to learn to manually tweak.
Has this been updated yet to work in DS 4.20?
Sadly, the ghost light doesn't work with 4.20.
But the Iray Ghost Light Kit One works well.
Im on 4.15
Can anyone tell me the difference between using this product (which I purchased) and spotlights?
Thank you
