How can I make the map with more light?

Hey everyone! :)
I some streets and stuff like this in DAZ3D but when I put light in the option Environment Intensity its give me to render only in 7% , I mean If I make it more the render take a loooot more time.
I have the idea with PointLight but it makes shadow and stuff like this that I dont want to.
Have any more good ideas for making light? Thanks! :P

Maybe try increasing "cm^2 Factor" in the Tonemapper Options. That seems to be a popular solution.
I put it on 20 and its still very heavy and not render fast , also it makes my character her glowing eyes all the time , I need to put less as well like the option I said before? Thanks ^^
Cm^2 factor 20 seems like a bit much. 1 is usually default. Maybe try something in between?
Honestly it sounds like the problem you are having is likely because you're used to rendering on your GPU and the scene you're trying to render now is using more vRam than you have available, so it's rendering on CPU, which takes MUCH longer. Does this sound right?
Well maybe but I use 3080 Asus Ti for my rendering , I also render on 4K sometimes render take me 20min with map , If I wont use light its take 8min to render it
I'm not really understanding what you mean by map in this context. I'm maybe also not understanding what you mean by "if I won't use light". I mean, there has to be light coming from somewhere or you won't be able to see anything, either an HDRI dome, the Iray Sun Sky Dome, mesh lights, or spot/point/distant lights.
Have you tried saving your scene, closing Daz, waiting for it to close completely, restarting Daz, and then rendering? Sometimes vRAM doesn't clear completely when trying to render multiple times in the same session of Daz.
Yes I do do that , Sometimes I make few renders and when I see it slow I exit and enter DAZ again , it render cery fast.
And what I mean about the light its when I use Environment Intensity and cm^2 Factor like I up it to 10 from 1 the rendering time is up , like if I make this render in 10-8min now its take 1:30 hour.
For some reason its all the time change the Exposure Valiue , I need to reset it and make it on Shutter Speed?
It's possible that whatever street scene you're using could be making changes to the environment and tonemapping settings, some assets do that sort of thing. Sometimes I push the Defaults button on the render settings and then change things to what I think they should be. I don't know if that will help.
What are your Iray Compression settings? Changes in that will definitely make a render take longer or force it to drop to CPU when it rendered fast before. As far as I can tell some assets will make those settings change as well.
Another thing to check is the Lighting Resolution in the Environmernt Settings tab. Some HDRI set that by to a match the resolution of the HDRI which will use lots of resounces, and isn't really necissary. It may help to open a new empty scene, which should reset all Environment and Tonemapping to defaults, and make a note of what all the settings in the Environment and Tonemapping tabs are. Then you can open your troublesome scene and change everything to match the defaults.
I don't know what figures, props, or architecture you're trying to render, but sometimes things are set up with shaders that aren't really compatible with Iray and that definitely makes trouble when trying to render. I've come across things that cause rendering to use tons of memory, render really slowly when they don't seem like they should, and just plain crash Daz when I try to render them. Sometimes I'll go throu and select all the surfaces in the architecture and props and double click on the default Iray Uber Shader, which should convert everything to work correctly with Iray. Don't do this with Genesis 8.1 figures because they're usually set up to use the Iray PBR skin shader and won't look right is you change them to use a different shader. Sometimes this will fix scenes that weren't rendering quickly or were crashing the render engine entirely. I've created a few scenes that no matter what I do, just won't render. With that said my GPU is a 1660ti that only has 6GB of vRAM so I would imagine that you would have less problems with twice the vRAM. I usually end up rendering on CPU because of my GPU limitations.
Last and probably most importantly when was the last time you updated your GPU driver? Even if you're sure it's up to date, I've noticed that WIndows Updates will sometimes change it, and usually not for the better. I could be worth it just to install the same driver that you think you already have running. Sometimes that will fix render problems too.
Wawww thank you for all the information!
About my Compression settings 512 on 1024 .
Lighting Resolution 512 Defult
About the drivers and all that I think 3 weeks ago if im right , I bought this graphic card one month ago +- the ASUS 3080 TI.
And thanks again for the help hope I can fix it ^^
Also the picture I want to render have some details like cars and street with lights they self , But when I redner without change the settings its take 7min , but its very dark..
If you need picture of what I do in this 3d and its may help you tell me and I will upload the two renders with the light settings and without.
BTW stages some times have Iray and 3Delight whats better to use? ot its don't matter so much?
Pictures of exactly what you're talking about are always a good idea here in the forum.
If you're rendering in Iray then you deffinitely want to use the Iray materials.
3 weeks is a while. There's definitely newer drivers for your GPU. I should add that it's generally a good idea to use NVIDIA's Studio drivers rather than the Game Ready ones. Updating or even re-installing the same drivers is always the first thing I do if I'm having any rendering issues.
Those Lighting Resolution and Iray Compression settings should not be causing this, in fact you definitely don't want to set either of those to lower numbers. Once whatever is causing this issue is resolved you may want to experiment with Doubling or even quadrupling the Compression numbers. Higher numbers for Compression will give you clearer more defined textures, at the cost of using WAY more vRAM. I generally set them low for complicated scenes and high for simpler ones.
Thank you very much!
The picture I render down below. Also I want to say it again when I wont change anything its take 32min , when I put lights with cm^2 Factor and Environment Intensity like 20% the picture below its take 2:10 hour. The real picture on 4K but here i make it on 1000 pixel to upload it to the site hehe
It will sound strange but I install the NVIDIA's Studio drivers and it so bad! I mean it was render on 30min +- now its take 2hours same render without using the cm or environment , But I fix it after I do check for update in the device mananger and now from 30min its 26+-min , so thats good start but still a lot of time with the cm^2 Factor and Environment Intensity , pretty sure I do something or its just like that because all the details in the map and the shadows xD
I start to think that not only the light make it a lot of time , I think the map is heavey as well , other maps without the CM2 and ENV take me to render 10-15min , and this picture take me 32min.
Did you restart your computer after installing the NVIDIA Studio Drivers? I've never hgeard of anyone having better results with drivers updated through Windows Device Manager before.
Since you can't see the sky in your render, maybe try using the default "DTHDR-RuinsB-500" HDRI that should be able to find in Smart Content > Render Settings. That's the one that loads with a default new scene and it doesn't use a lot of resources.
It looks like there's quite a bit in that scene. A Sci-Fi city of some sort, Neon type mesh lights, metalic surfaces, Two figures with it looks like dForce clothing, hair, a fairly detailed car. I would expect that scene to take a bit of time to render.
Yes you got it right the map is slow the rendering because she very very heavey! I try to render all the picture without the Street and its rendered in two minitue!!! With 20% cm^2 Factor its super fast.
But I really liked the map , so it means if I want to use this map with cm^2 Factor I need to do the slow rendering because the map is heavey? other map runs fine like 40min+-
I'm still not sure what you mean by "map". Are you talking about the Street and Buildings?
Yes , If I remove this street and buildings and make it empty with not background its render the 2 girls and car for two minitues with 20% cm^2 Factor , If I change street and background its take like 30-40min. so it means the stage i use right now is heavey no? or something else in my pc? or all good? Also when I up the cm^2 Factor for more percentage the render time up , it's supposed to be like that right?
Of course if you remove the entire street scene and buildings it renders fast. The reason you're having this difficulty is a combination of all the factors. It seems you may be looking for an easy answer, and there likely isn't one.
It sounds like the Street Architecture must be huge. Possibly you could try to delete the parts of it that you actually can't see in the camera frame of the render. It depends how it's set up, multiple pieces or one piece. It also could be textures on the architecture. There's no way for me to know.
A scene like that would likely take me many hours to get a crisp render like that because I have half the vRAM available on my GPU compared to yours, and would have to render it using CPU only.
I suggest spending the extra render time using google to search this forum and learning about the inner workings of DAZ. Learn about lighting. Learn about why some scenes render fast and some slow so it's not such a mystery. The more you understand about that, the more easily you'll be able to overscome obstacles and render the scenes that you imagine.
Yup that's what I did! I deleted some parts in this streets and the render goes very well with a lot less time , This map is heavey but I really like it.
Thank you for the amazing help mate! Your awesome! You learn me a lot! ^^
