Well I thought I was on the right track, I altered things to bring the image closer to the one above,
I thought it looked fine, but obviously still had many more things to alter.

Having bypassed the srgb utility node on all materials, and re-checking the AO was multiplied according to the new way of thinking
(not sure it's correct way of thinking) I found myself going back again & re-enabling them all(for some crazy reason)
I was in a place of predictable render result that looked ok to me.
I wrestled with many materials trying to get rid of spec dots that suddenly started appearing,
dont think I found the source(though as I edit the text I wonder if the sundial is the culprit),
and now after turning back on the srgb-linear(but rendering tone mapped)
the image is much darker and gone is the smoothness of the image(AA&Mat samples seem to low now).
Sorry for rambling on, I know nobody else who might be interested, infected with the Clarisse Bug.
As its now darker (render time doubled)the materials/spec /reflection is more prominent but because of the poor resolution look
I now have to figure out what needs to change, I wondered if i'd mixed my normal maps correctly
ie a mix of 2 materials has 2 normal maps, I have them going into a blend with mix/mask texture,
I decided to look into it, and found a tutorial splitting each to rgb and recombining, which looked handy to know about
but as I wasnt trying to have both combined in this way, I figure the way i've done it is a little easier & hopefully isnt causing any issues.
Just discovered the castle material i'd changed back to didnt have the srgb-linear, now i'm back to something perceptually better than before,
I've replaced the emissive bulb in the street, and positioned the sphere light to replace it, but I decided to flip them 180 thinking the throw would be better, didnt like the ies so trying the standard for a change...and so it goes on...

16aa & 16spp before was fine, though all light samples are on 1, not sure if having all samples on 1 only works with adaptive rendering,
and now it seems to be pulling back into shape with 8AA & 16spp. Ticking away the moments that make up a dull day.

Many little changes, probably many more to do, think i'm only using less than 5% of the power of Clarisse, though not sure i'll ever get past 10% there is so much I know I will never know. I thought this looked ok when working on it, but now looking at it uploaded on different computer doesnt look so good, gamma on island/fog or too much top light? Also had much darker version with darker clouds. At the start I didnt have falloff on any of the lights, thinking it was easier to light & maybe easier on the CPU, but curiosity took over and I decided to use it, to see if it made a difference, ideally to realism. but wonder how much longer I can keep playing with the same thing over & over, like mixing a music track with endless replays.

Real moon, that's from a Clarisse user :D

Great !

Thanks, I know it should be an over exposed tiny dot way off in the distance, but where's the fun in that, if I really wanted realism i'd have to move it far far away...How many Clarisse users have modelled threads on all nuts & bolts :)

There really isnt any reference shots of the island at night, it's actually pitch black on the lake at night.

Not sure how these look for others but they looked ok my end, in over 30yrs on computers
I've never colour proofed a monitor or used a spyder thingymabob, but only now do I wish I knew more
of so much more than I ever needed, but it really is too late to learn, all the things I wanted to
so many tools I thought i'd get around to, but now doubt I ever will.

The only reason for the 2 islands in this uninspiring arrangement was down to not knowing what I was doing.
After importing the castle I copied it to another position, and all the extra's where added to the second moved items,
so my combiners & groups are all over the place, as is the project hierarchy.

I tried to use the real world geo for the lake mountains, but wasnt impressed with results, the displacement map seemed to have errors in some places creating thin jagged peaked ridges where they shouldnt be. Wanted to make a couple of single mountains in terrasculpter, but ended up with a whole range, good enough for now but always room for improvement. The temptation to at least try to add trees to the mountains & tiny low res, simple Italian Lake buildings shouldnt take too long. There must also be a way to feed data/mask from where light lands on the moon, to an emissive version, only emissive in the crescent.

Still not managed to get the moon contributing into the clouds, but it's probably the sun in the wrong place, also not transmitting the sun through a blue/curved atmos, not sure if adding a sphere the size of earth would help. Obviously the moon would be brighter in most pictures, but things could be a lot more intuitive if camera aperture/exposure/iso where somehow accessible?

The recent tutorials from Sam & Eric where excellent & made me think they where talking directly to my issues, though I haven't had the chance to try out any of the tips, I feel like they will help a lot. As would a reference monitor or a new HDR capable display, I have tried to optimize the scene, rather than crank up settings & render times, by not having DOF or SSS or Inverse Sqr falloff or anything else I think of to reduce or turn off. I'm not sure how much better the image could be with those subtle things added or with sample increases. Wondering if you have 20 or more lights with low samples is equiv to one light with more samples? obviously not exactly as you would only have light coming from one direction. Also assuming that rendering in 32bit needs more samples than tone mapped/clamped image. I was trying to make some simple buildings for the mountains, it would be good to make them proceduraly, with blenders geo nodes but my laptop isnt even able to run blender, which I also struggle to get my head around the interface & way of working, I had to install an old version and gave up after about 5min, tried searching for some other simple 3D modelling app only to find nothing suitable, except mecabricks. Having watched a few Houdini videos I realize I'm never going to become proficient with it, understanding overall concepts isnt quite the same as getting deep into the nitty gritty of the latest DCC apps, & now there's just not enough hours in the day, or years left to live, it maybe 5 or 10 years before I could get access to threadripper performance plus good graphics cards & Angie, and then that would require a little more study, you have to keep up or get left behind, I wonder if Elon Musk perfects Neuralink we could get Clarisse knowledge on a chip? Though maybe better to just connect into Nvidia's AI painting app https://www.youtube.com/watch?v=jl0XCslxwB0 & have it take references from dreams while sleeping...who knows where things will be in another 10 years time.

This looks interesting & ideal for the distant buildings but i'll be damned if I ask the American Government for something
