Buying a CPU for 3Delight

I have recently started dabbling with 3Delight because I found that I can render multiple characters and an actual envirment like a club interior and careful crafted lighting...........much faster than I could ever dream doing in Iray.
I have heard that you can get faster renders in 3Delight if you have a CPU with more cores. Well I looked up a few CPU's and some even go up to 64 cores I cureently have a I7 8700 with 6 cores, so I am curious about how mush I might gain in rendering speed in 3DL if I got a CPU with many more cores. How much improvement can it make? If I got a Ryzen CPU would it have any issues with a 2000 or 3000 series RTX NVidia?

Forgot to attach a picture before, but this is an example of a test scene usin 3 fully clothed G8 characters with Dreamlight Stage FX pro with a fog pane and tranlucent light props and full stage 1080x768 resolution, and this photo rendered in 15 seconds with the system specs mentioned above. Since I do animation I would like to cut render time and get about 6 to 8 frames a minute. So would more cores do the trick?
I believe DS was once limited to 8 cores but these days I think it's unlimited, so the more cores the better it will be for you. How much VRAM do you have? You don't really need a NVIDIA card if you render in 3DL
Well I want to render in both Iray and in 3DL. Iray for more realism and and a single character 3DL on larger scenes with more characters. I have a GTX 1080 right now and 32 gigs of system ram.
Where could I look to find out if DS supports up to 24 or 32 cores? Is there somewhere that DS technical data is listed?
3Delight certainly now supports 24 cores. As far as I am aware the version bundled with DS never did have core limits, unlike the stand-alone version.
Just tested - seems to max out my 32 core/64 thread Threadripper 3970X ok
Thanks Richard and Jack ! As I said my system currently has an I7 8700 6 cores 3.7 Ghz, if I replaced with maybe a Ryzen 32 core how much improvement (speed) would I see with 3Delight? A vast difference or just slight?
If you have a test scene using standard content (or if I have the non-standrad content) I am happy to give it a test render on my 12 core/24 thread Ryzen.
5-6x increase..? probably more considering the boost clock is higher. I think mine does 4.something on all cores.
Richard , do you happen to have Dreamlight's FX Pro, Time for School Asia (G2) nene hair, AD 50's ponytail and Zac Hair. Those are what I used in the attached photo above. I assume I could just go in my scen file and copy the DUF and send as an attachment here.
Well, I have Zac hair...
What standard environments do you have, maybe you could but together a somewhat system heavy scene with a tasking interior and lighting that I can recreate or you could post the DUF for. Let me know your render time, and I will test in my system.......................if I'm not asking too much.
I have never realy pay attention to core management, but if I get a Ryzen with 24 cores is there something I need to set up in bios or in DS to make sure it will use all those core when rendering in 3DL?
No, will just work :)
I always get so confused by technical discussions like this. So Studio and 3Delight can utilize multiple cores, okay, fine -- but what about threads? What's the difference between cores and threads, and how will the quantity of each affect Studio's performance?
cores = physical hardware
threads = software processes/instructions
Since all modern CPU cores are multithreaded, just get the CPU with the most cores you can buy within your budget.
If you want to do animation, have you looked at the new Filament plugin? That could be a better option for you, after all it can render in near real time like a video game even at higher resolutions.
And there is no issue with having RTX installed. 3Delight simply doesn't use a GPU, whether you have one or not.
I'm not sure, off the top of my head. I have soem of Stonemason's winter sets, I'm pretty sur at least one of those is 3Delight with atmosphere. Also most of Jack's sets of coruse, but not sure how many of those come with pre-loaded atmospheres if you want the test to include that.
Outrider are you talking about the Filament that came with DS 4.14, or is there a seperate Filament plugin for purchase that needs to be installed. I did in fact make some attemps to use filament and I just was not satisfied with the results. In paticular I could not find any hair that worked at all. But I agree, it was lightning fast. I attached a couple of photos of renders I made with 3DL and I am still not totally satisfied with the looks of the character's skin, but I was able to add an environmet with mutiple lights with tons of translucency effects and geometry and the scene rendered in 10 seconds. If I can get 6 frames per minute that makes animation some what feasable. I have not seen the latest updates to filament so I would not rule it out (if they fix the hair thing).
Richard, I think I have the info I need to make my decision on getting a multiple core Ryzen, I am absolutely going to do it thanks for the feedback you and everybody here helped me decide.
Now I just need to start learning all the ins and outs of 3DL lighting, shaders and materials. Thats is already a pain, since I have the Advance Spot Light but get a completely dark character with only the cornea illuminating slightly even if I turn light intensity all the way up. Any ideas why???
Umm...no, not seen that happen. Try uninstalling/reinstalling! If that does not fix it, maybe post your light settings...
Is it possible that you set light falloff to custom and the character is outside of the range? Or set surface flagging to not illuminate surfaces with 100 diffuse strength or something similar?
