Does anyone know why I cant seem to use spotlights and ghost lights together? this has been going on for a while and I've just been lighting my scenes in other ways, but ghost lights are useful so I would like to get them working, This issue is with both SY Invisilights and Iray Ghost Light Kit One I will provide some images below which I hope will show my issue more clear than I can explain

Image one this is just one spotlight that I am basically faking the sun with for demonstration purposes, and the hdri in the background as you can see everything it working fine, the noise clears up relatively quickly and I've got some okay basic lighting going on

Image two this is with one ghost light on from the Iray Ghost Light Kit One kit usually I will perhaps put them near the windows to add a bit of more light to the room, as you can see the spotlight is now just a noisy mess especially compared to above image, If I render like this (I've tried) I'm looking at a very long render, I've also left it for a while to see if it clears up in the viewport, it don't

Image 3 basically same thing as above just with a different product, When I first purchased these products they seemed to work with spotlights fine, as far as I can remember, also I can add mesh lights or point lights and everything works just fine, it's just the spotlights, Oh and just to mention I am using spectral rendering here but the problem is the same with it on or off so that is not the issue. Maybe I'm just being thick and this is to be expected, but surely using ghost lights and spotlight together shouldn't result in this noisy mess and massive increase in render time?

I seem to remember that when 4.20 & VDB's appeared, the currant crop of ghostlights don't work properly. Then this one came out , which should work properly.

Thanks I will give that one a go, I was under the impression that SY Invisilights were a post 4.20 product though, not sure about the other one I was using though

I think it's KindredArts second ghost light set, I'd need to check on when they all came out, but those 2 of yours are older versions...

I think this is normal. I ran a test where with one ghost and two spotlights my render took 28 minutes. With just the ghost it took 17 minutes. With just the two spots it took 8 minutes.
I would be pretty happy with a 28 minute render, In my case if I use a spotlight and ghost lights together its going to take a couple hours at least to clear up the noise, I remove the ghost light or the spotlight from the scene then it will be done in 15 to 30 minutes, It just doesn't seem right to me, I can just use like a mesh light or a point light instead of the spotlight, that solves the issue, I'm just a big fan of spotlights.

Well, this one took me six hours. I'm using a 3090, rendered in 2K at 99% convergence. I had three spots on the model, a fourth spotlight coming through the window, and a large overhead ghost light. Bloom filter on, max path length -1. Several reflective surfaces and the space behind the model is walled in with everything retextured from the way the asset came. I'd love to have someone tell me that it shouldn't have taken six hours, but I wasn't able to get a better result with different settings. 3-4-x1.jpg

Nice render by the way, The only reason why I was thinking it was some other sort of issue was because when I bought these products a couple months ago they worked fine, I had no issues, render times weren't that much different, then all of a sudden no matter what my lighting set up I started having this problem, it doesn't matter if I have a really basic light set up or a really complex one, as soon as I use try to use a spotlight and ghost light together the spotlight starts creating tons of noise, If I replace the spotlight with a point or mesh, render times will return to a reasonable time, But those don't really create the same sort of light you can get with a spot.

I'll be watching to see if anyone can offer a solution.

And thank you for the compliment. All your work is S tier, my friend.

Thanks for taking the time to trying to help me out, like I say I can get by without ghost lights, it's just they are really useful at times, mostly for daytime interior scenes, which is an area I still really struggle with.
