Hardware / Re: I NEED HELP with a PC build
« on: 2022-11-18, 13:47:53 »
I don't even think you can get a 3xxx series Threadripper anymore and if you do it is probably going to be really difficult finding a motherboard for it - seems like everything went EOL really quickly. There might be a SIs still sporting a few though.

I do agree with Juraj, 7950x or an 13900K build seems to be quite the sweet spot for your budget. The next gen (although previous gen compared to consumer parts, Zen 3 vs Zen 4) Threadrippers are now PRO only which means you'll get a ton of PCI-E lanes you don't really need for rendering and it will cost you quite a bit. These are still the way to go if you are after top notch performance but they will be quite a bit more in that "workstation" pricing tier that is just a lot more expensive than what you get on the consumer side with the above suggested CPUs.

In case you do want to do the math, the 5975wx is the 32 core Threadripper now and the 64 core one is the 5995wx.

Can't say I noticed a difference anywhere when I upgraded my 3970x build to W11. All smooth... Well, smooth as it can be for Windows meaning weird updates bricking things left and right and changing settings and all that (which applies to W10 too) but besides that functionality all good imho. The 5995wx I haven't really tested on W10 but W11 works fine and as I'd expect it to - with all the Windows being Windows included.

Try throwing that entire setup in a Remesher generator, I think it could do the trick. Otherwise maybe try playing with the adaptivity in the Volume Mesher, setting it to 1% is typically more than enough.

Glad you got it working and yeah, buying more RAM is typically a good idea as once you start running out of it... Its trouble time! :) Happy rendering!

Howdy!

You can see on that screenshot of yours that you're running out of your system memory (RAM) and because of it things that should be in RAM start getting offloaded to your SSD. Even with the fastest SSDs you can buy you'd still be order of magnitude slower than if everything could be properly loaded into your RAM. Basically Corona needs to go search for whatever it needs to do its calculations into a device that is tons slower. The rendering speed in these situations can get drastically lower but on the upside, it'll still render.

As to why your laptop can render it fine with the same amount of RAM I would guess is because you have less memory intensive applications open in the background (like for example post-production tools or multiple 3ds Max instances etc...). Can't say for sure though.

As you noted yourself, a faster GPU will not help you much in this situation as pretty much the only thing a GPU does in Corona is denoising (in the IR or if you have the Nvidia AI denoiser selected).

What I would suggest doing is to either try simplifying your scene so that it fits into your 32GB (and see if it renders appropriately faster) or look into buying more memory.

Hope that helps!

Personally I tend to keep the last 5-15 materials I'm working on in the same canvas but as you noted yourself everyone's workflow will probably be a bit different. When I do have 15 materials in one node view I try to clump them together thematically - so all the wall and floor materials and such are clumped in the top left "corner" and foliage is maybe next to that group but clearly visually separated. That said I also don't really mind dragging and dropping materials in the node editor at all.

You can also try creating new views (View -> Create view) for the subcategories of your material types. For example, all the architecture stuff could go in the architecture view and all the foliage materials could go in the foliage view. That is something I also sometimes do myself to keep things organized a bit better.

The thing with the node material editor being the way that it is, is that it allows you to have multiple unique nodes in front of you. That can be super useful because you can then also share nodes between materials real easily without having to kerfuffle with "reference" nodes and such. For example, if you set up a nice noise shader and you want it to be driving multiple materials at the same time... You can easily just plug it into multiple different / unique materials. Then if you make changes to it you can simply just make those changes and because that one node is plugged into other nodes everything will adapt seamlessly. So this way you can truly leverage the power of nodes.

As for the "nodes dropping on top of nodes" that is something to potentially be improved in the future.

[C4D] General Discussion / Re: How to use Chaos Scans
« on: 2022-10-25, 09:57:07 »
In case you're like me, I don't see the world icon, but that area is clickable. I may submit as a bug.

You can also go directly to the library on the web at:  https://download.chaos.com/vrscans
You'll need to log in. The downloaded files, in .vrscan format, go in the slot picture above or you can click the button to find it and add it that way as you would with an image.

Please do submit that as a bug so that if it is indeed is not showing up correctly we can fix it up for others as well. Never mind this part, noticed you already reported it, thank you!

As all the above posts have suggested though, you can get to Chaos Scans via the web icon inside the Chaos Scanned material or by just simply going to the website quoted above.

We also just released a tutorial on the basics of Chaos Scans which might be useful to you - https://www.youtube.com/watch?v=hK4EFPgCJEU

Hope that helps and I'd also like to thank all the posters before me for chiming in and helping the OP! :)

Hello.
I have a 3995wx with a Noctua NH-U14S. I  have also added a secondary Noctua 140mm NF-A15 HS-PWM and a couple of  Noctua NF-F12-PWM 120mm Fan to help with airflow.
When rendering I am regularly getting temps of over 90c. Last night the max package temp was 93.6c!
Has anyone got experience with effectively cooling this chip? Seems like I need to look at something with a bit more power.

I think something must be off there, I can't imagine a 3995wx getting that hot with a Noctua NH-U14S unless you are doing PBO on it (AFAIK some WRX80 boards now allow that) or something is off

For reference, my 3970x is getting max 70c with that cooler (with PBO it can boost to 80c something but comes to down to 73c after mere seconds) and my 5995wx with an upside down NH-U14S maxes out at 70c.

Really seems off for some reason :\

Thanks for the reply. This is a bit worrying. What would be your first steps for troubleshooting the issue?

Honestly I would first probably go and check if PBO is on and if any of the voltage settings are not set to AUTO or whatever the default / proper setting would be. I'd probably consider resetting the BIOS too. It sounds to me like your CPU might be boosting itself into oblivion.

If that is not it I'd look into what Romullus said and re-seat the thing. If you do that though make sure you wipe the existing thermal paste with proper tools and not a 1 cent napkin that will leave fabric residue on the ILM - that would not be the best. I sort of doubt you'd get 93.6c just because of the thermal paste not being applied properly but then again I've been proven wrong before lol.

As for the 5995wx, lottery would be nice, ha! This was pretty much just saving money for years and years. Seriously thought about other options although this ultimately made the most sense all in all given the workload. Suffice it to say I don't plan on upgrading any time soon even if I wanted to :D It is a real treat working on it that's for sure and it's really helping me out.

Hi Nejc, I went for the 5995WX too but I'm struggling with it. Temps are ok but when using the IR in C4D things are virtually unresponsive. The speed is great for final renders, but getting it to a point where it's ready to go is very frustrating. Any tips from your setup?

Howdy! Congratulations on winning the lottery to you too! Jokes aside, its a fine CPU for just about anything I'd say.

The issue you are describing is most probably the same as in this C4D thread (https://forum.corona-renderer.com/index.php?topic=37900.0) and we are aware of it and are trying to fix it.

In the meantime I'd suggest reading through that thread as I offer a workaround for the time being which is to disable SMT. That will lower the performance ceiling for the CPU as you'll effectively go from 128 thread to "just" 64 but the performance loss is less than that - I noticed about 20-30% which is still faster than say a 5975wx. More info in that thread and I'd really like to stress this, we are aware of it and the suggestion above is just a workaround for the meantime.

Also, if you raise your hand in that thread that'd be helpful in case we might want to contact you to run some profiler tests.

"You need to plug your Edge Trimming map into the opacity slot of the material of the object that you are scattering"  What's the process if the material already has an opacity map?

In that case you still plug the Edge Trimming map into the opacity slot of the material of the object that you are scattering but then you also plug the opacity map you are using into the Edge Trimming map itself. :)

The static pressure required to feed IceGiant means that when noise normalized to reasonable amount, it didn't even beat Noctua.
It has far higher thermal ceiling that is for sure, but I doubt that is preferrable in workstation, even NH-U14 can get too loud with above 1000rpm single-fan.
If you run Threadripper under 300W limit, there is no point to it.

I am more baffled there still isn't single good reliable AIO for the socket, esp. with popularity of Epyc. It would be one AIO for big market (Threadripper, Threadripper Pro, Epyc of all gens,..).
Just weird, not one one.

BTW:
my 5995wx with an upside down NH-U14S maxes out at 70c.


Did you win lottery :- D ? Nice.

That is an interesting remark about the IceGiant. I mean the temps from all the reviews I've seen are just fantastic and the noise doesn't appear to be an issue per say - but I haven't tested it myself so its all on the "I read about it" basis :) Could be useful if the Zen 4 Threadrippers will boost up to 95c as their desktop counterparts lol.

Also there really isn't anything stronger on market. This is it unless you plan custom water-loop.

While I'm a huge Noctua fan I'm still a bit bummed out that we can't mount an IceGiant onto the WRX80 motherboards. IMHO that thing is the best of both worlds but its only for sTRX40 motherboards (the socket is rotated 90 degrees on the WRX80 platform).

AFAIK this is already available via the little dropdown menu under displacement, mind giving it a twirl?

edit: Bengamin beat me to it it seems :)
