[Max] Bug Reporting / Re: All scene assets disappear from VFB and scene crashes

« on: 2025-06-18, 13:56:46 »

Hi, I wonder if someone can help me understand why this is happening.

It tends to be on 'heavier' scenes, but randomly my scenes will crash during interactive rendering when making really small changes. Prior to the crash, everything in the VFB will instantly disappear, and then lock me out of stopping the interactive running and saving.
It tends to be really sporadic and doesn't really seem to follow a pattern or happen when I am editing certain objects/materials. I have a feeling it may be something to do with scattering large amounts of grass objects in a Forest Pack but I don't seem to be to replicate the issue with any consistency. It catches me by surprise when making the smallest change to a material for example.

Any ideas welcome and thanks!

Carl

Hi, did you found a solution for this issue ?

Thanks for the replies, seems we are on the right track.

Can you please just try with a wired mouse to make absolutely sure this is wireless issues, and not something related to Corona-Max updates?

I have the same issue.
With and without wired mouse.

[Max] I need help! / Re: material editor SLOW - i think its a CORONA issue?

« on: 2024-09-23, 15:44:00 »

I have tested this on two 64-core workstations and one 24-core workstation, and the issue is only occurring on the 64-core workstations.

I will oppose all the advice in this thread, because I can already tell you, it will not help. Any big-PC (Threadripper, Xeon, etc..) in high-core version, is pain like this in material editor unless as you correctly shown, you use native Physical Material.
Corona, will have super slow material editor in any remotely sized scene. And it's not snappy even in completely empty scene, unlike native.

This has absolutely nothing to do with proxies. This is technical issue on Corona's side that they just don't care about. I guess majority of users aren't on 64-core machines.

BTW, my settings:
Standard viewport (so no HQ)
Every big mesh is proxy. (most of long opening is due to bugs like "corona assets" etc.. and similar stuff, having proxies makes scenes smaller, but it hardly makes difference in opening after scenes start to feature bloat).
Viewport texture settings 1024px for all 3 types(laughably blurry, so despite having 16GB of Vram, I only use like 2GB per scene because otherwise everything will be even slower).
Basic material editor for editing materials. I only use Slate to create them, but because it's so slow, all the little changes (changing IOR 10perc. here or there, etc..) I do in basic.
All textures mapped locally, on local disc with exact paths.
No plugins whatsoever. No ForestPack, no nothing.
It doesn't matter which Max version. It's the same as long as I can remember. Really makes zero difference.

It's not anything else, it's Corona. Yes you are correct.

This does in no way help with slow material editor, and esp. slow material editor during IR. That's like unusable, I waste like 90perc. of my time and 99perc. of my mental health waiting on shit to unfreeze.
It's what it is :- (.

If it's really all because of QT, then that should have been tried ages ago.

One thing I never tested, if it's connected to materials being applied to scene ( and/or additionally, having "shown in viewport"). So I will test:
- disable show in viewport in big heavy scene
- dis-apply all materials (I don't know, apply them to single box and hide it) just keep big material editor full of materials.

[C4D] I need help! / Re: AMD 3990X massive slowdowns

« on: 2024-08-12, 13:48:14 »

I've noticed the same issue on both the 3990X and the 5995WX; they behave similarly, though it seems the 5995WX is even worse. I’m working with an almost empty scene, just a single box, and when I start interactive rendering, the PC becomes nearly unusable. Interestingly, it actually performs better with more objects in the scene rather than just a single box or an isolated object.

In contrast, my 3960X workstation doesn’t have this problem at all. It seems this issue is specific to these high-end workstations with 64 CPUs and 128GB of RAM.

Hi Guys,

I have a workstation with a Threadripper 5995wx CPU.
I have 128 GB RAM (32gb x 4) running at 3200 MHZ.
I did the Corona Benchmark in the morning (benchmark 1.3 and the new benchmark) and I got some good scores: first one 17 seconds, and the new benchmark 22 843 900 rays/s.
I've got a Cooler Master ML360 TR4, and the temps are 65 under full load.

I've installed AMD Chipset drivers, and now I get really bad scores (33 seconds, and 15 897 916 rays/s)
I have uninstalled all the AMD drivers, even restore the windows (to the point of having nothing, just right after I've installed the windows), and still getting these bad scores.

Even my other 3990X gets ~ 21 000 000 rays/sec.

I've attached the screenshots, on the left are the first results, and on the right the one that i have now.

I don't know what I am missing but maybe you have some advice.

I mean...you can just run the benchmark 20 times and the result for 3990X will be anywhere from 17 to 20 seconds. It just isn't a good benchmark at all, outside of all the randomness introduced by actual voltage, current, room temperature, OS overhead...

I can't believe people get hang-up on something like this :- D.

You were right. I moved my PC in another room, and I left my front case open without any dust filter  (Define R6 Case) and voila, the CPU temperature dropped from 80 to 65 degrees on heavy load, also the CPU speed increased from 3.2 to 3.5.

I have no interest in benchmarks. With XMP enabled @ 3200 MHZ, my CPU it's stuck @ 2.9 GHz in Corona. At 2666 MHz my CPU it's stuck @ 3.3 GHz, so maybe for 5K does matter. My default RAM works @ 2133 MHz but I didn't tried that yet, so I've got to do some tests.

So this is weird...when I enable XMP on my 3990x build (or actually d.o.c.p. in this case, first I've heard of that acronym) and bump my RAM from 2666 to 3200mhz my benchmark rate actually worsens.  I go from 17 seconds to 18 seconds, every single time.  I wonder if the system is pushing CPU clocks down because memory clocks are higher?  Temps don't seem to be a problem, I'm upper 50's lower 60's for CPU.

Not a huge deal, but odd!  Currently stepped back from the faster ram speeds since I can't see any benefit?

I have the same issue, did you find any solution ?

@lolec - what is your RAM speed and infinity fabric clock? (IF clock in BIOS)

Ideally, they should be "coupled" - e.g. in my case 3900x with 2 sticks of RAM running in dual mode at 3600 MHz and IF clock set to the default of 1800 MHz. 

Oh and you can also check enabling different power plans in Windows. Download and install Ryzen Master, and then activate the AMD Ryzen High Performance plan.

In power plans I can see just the AMD Ryzen Balanced. How can I activate the High Performance one?
Thanks.

Hi Guys,

I have a question. Yesterday I ordered my 3990x build, but as a cooling solution i've added a be quiet! Dark Rock Pro 4 TR4. I've watched some testing on a 3970x and it performed pretty close to Noctua, but i couldn't find any testing on a 3990x. I didn't chose Noctua because of looks, i really hate that shitty colors. Later i checked on be quiet! website and on specs are mentioning that DRP it recommended on a max 32 core CPU. Should I worry about this ? Does this influence the performance of CPU?

You can see that on my photo one page back as well with what are not even low-profile memory modules. Also..with 2x A15 fans. But I tested that configuration one time before already and the result was the same this time, there is no thermal improvement (after all just 10 cm to the left is Case Exhaust fan again, so it's basically 3x vs 2x. The heatsink is too narrow and it creates very annoying resonating turbulence. Noctua A12x25 (120mm) fan would probably give better result for this situation and with much nicer sound profile.
(It's incredible how much more advanced the A12x25 is compared to A14/A15. Even at same noise level...the noise is super pleasant, low-pitched humming car engine, not high pitched jet engine.)

Is the Great Wall M1200 PSU something you already have? If not, I would suggest changing to something more reputable like Seasonic Prime series (or Corsair AXi which is also made by Seasonic except for 1600W top model).
Any reputable brand (BeQuiet,..) or OEM (SuperFlower) works but your choice is bit obscure. High-end PSU is paramount to stability of PC, but esp. for 4000 euro CPU.

Any reason for going with 5400 RPM HDDs ? Are these just for back-up? Because otherwise they're far too slow,..even for backup.

Then I will add an extra A12.
I choose that PSU because I need to buy everything just from one store and the 1200w Corsair its double the price (around 500 euro). They have Corsair Professional Series Platinum HX1000i  but I'm not sure 1000w is enough because i'm planning to add an extra RTX 2080.
HDD are fore backups, but you are right, it's better to switch to 7200.
Also i'm not sure about 512gb A-DATA SSD- PCI, M.2, PCI Express 3.0 , even it has a lot of good reviews.

Thanks for advice!

Hi guys,

I want to buy next week a 3990x workstation.
What do you thing about this config:

AMD Ryzen Threadripper 3990X 2.9GHz box
Noctua NH-U14S TR4-SP3
GIGABYTE AORUS TRX40 MASTER
GIGABYTE GeForce RTX 2080 Ti GAMING OC 11GB GDDR6 352-bit
HyperX Predator Black 16GB DDR4 3200MHz CL16 1.35v   x 8 (128 GB)
SSD ADATA SX8200 PRO 512GB PCI Express 3.0 x4 M.2 2280
Seagate BarraCuda 4TB SATA-III 5400RPM 256MB x2
Inter-Tech GW-M1200, 80+ Gold, 1250W
Fractal Design Define 7 XL Black Solid

Also i want to add another Noctua NF-A15 PWM fan for CPU , but from my experience with another 3970X configuration, this will cover 2 slots of RAM, so you will have just 6. This happned with AORUS TRX40 PRO WIFI. I dont know if TRX40 MASTER its bigger.
