[C4D] Daily Builds / Re: Mac M1 LOW POWER MODE bug lives on.
« on: Yesterday at 10:59:47 »

The fact that other software can't run the CPU to its full capacity over an extended period.

Sorry Tom, but all Corona Team continue to replay that. I understand that every software developer loves it's creatures...and we love Corona Render too...but please could we try to analyse the fact that Cinema4D Cinebench or Cinema4D standard/physical rendering engine can handle the CPU up to 99% for hours without any overhead, without any CPU throttle and without any ISSUE on Apple Silicon Processor...?

Nejc Kilar is the only one said interesting things about the "different" part of the CPU used for calculations...maybe Cinema4D rendering engine takes part of the CPU for calculation that Corona and Vray don''s interesting. I don't know deeply how the pure calculation works...but what I know that Cinema4D push the CPU at it's best, Corona it doesn't...Science is a fact and numbers say that.

Anyway, I wrote many time about that Corona Render "sometimes" reach the 98% of the CPU...and after some loop renders on the same scene, continuous works or long period or "I don't know why", it falls below 800%...sometimes 750% of a total of 1000% of 10 core Apple silicon CPU. The Cinema4D rendering engine stay up to 990% of the CPU, this make the CPU Hot, not as my second iMac with Intel 10K generation processor that become very hot, but the CPU never falls below 990%.

I tested internally the behaviour of:

iMac i9 10K
Apple Silicon M1 Max.

We have the same Cinebench numbers: around 14.000 CB. So when I try a complex scene, my M1 Max and my iMac i9 renders with the same timing...M1 Max is a little bit speedy.. and stay cold..the i9 seems a phon and drive me crazy :)
I tried with a complex Corona Render scene and at first passes my M1 Max outperformed the iMac i9. But after sometime my M1 has fails with a 20-25% of processors percentage unused.

It seems a throttle issue, but it doesn't...

I want to repeat my question: way does Cinema4D rendering engine use 98% of the processor for hours? How different are the mathematical instructions sent to the CPU by Cinema4D rendering engine and Corona Render? Do you think is a good idea to try a Stand Alone Rendering without pass through plugin Ecosystem? Maybe Cinema4D creates a bottleneck?

This pictures from me are absolutely clear.
PS: I don't tested the low power on or low power off...I work with automatic corona issues come up with any settings.

Happens to all OS X users from the beginning.
Unfortunately the image editor is a total disaster.
Crash every time I close it without any action.

The thing is, further investigation does not seem necessary. We can't say how the native renderers in C4D use threads, how optimized they are, etc. What we can say is that Corona and V-Ray are VERY good at using a CPU to its full capacity, and this seems to be the problem as the CPUs or some other element in the machine end up throttling. Since no program can ever "make the CPU do more than it can do" that comes down to the hardware not keeping everything below operating temperatures when the CPU is maxed out.

The only solution would be to deliberately make Corona and V-Ray NOT run at full power, which would be somewhat backward. Of course this should be possible for you to control at some level by reducing the number of threads Corona is allowed to use for rendering, which may keep temperatures down (EDIT - or of course use low power mode, which is the OS equivalent of reducing the power of the CPU available for use). But ultimately the tests are pointing toward the fact that the hardware does not keep the CPU (or some other element in the machine) cool enough to avoid throttling when the full power of the CPU is used for an extended period of time, and that one comes down to the hardware manufacturer.

I don't totally agree with you Tom. Try to follow me: if you start a render with Cinema4D internal rendering engine, (I agree that we don’t know how it uses thread or how is optimized) you can push the Apple silicon cpu to near 100%. (I have 10 cores so around 998% CPU) My MacBook Pro M1 Max can handle a scene for many hours running without any CPU or GPU throttle. Sure you can hear fan running (medium velocity of course). If it was a hardware problem related the same thing should happen. Cinema4D can't tell to the CPU to avoid throttling so is very easy to make a conclusion about.

The fact is that Corona (I can't try any rendering engine that uses CPU unfortunately) uses around 80% of total cores after some passes or after some loop renders. Cinema4D can handle the full percentage of the CPU without any throttle.
The throttle it does not matter here, believe me.

About other kind of test with Corona Bench, I know that right now is not compiled for Apple silicon CPU, I seen on Trello about future re-compiling for M1. I think that a good test should be to try with a stand-alone app for to see what happen during rendering. Avoiding to pass through Cinema4D C++ plugin ecosystem is a good way to test the power of the compiled app.

It does not happen with the Cinema 4D native render engine.
It happens with Corona.
It happens with V-Ray.

Interesting thinks...maybe this can be used to investigate more?

Does it mean that "Only Corona has this issue"?

I mean that Corona Render and now also Vray has issue...
What do you think about Cinema4D Rendering engine has not issue? do you think that could be a "C++ C4D plugin behaviour" problem? I would like to know if a Corona Benchmark stand alone is afflicted from this issue or come from plugin ecosystem.
Anyway take it easy, we love corona render and we would like to see it render at speed of light on Apple silicon CPU...

- “Only Corona has this issue” - this is not true. This is not a Corona-only issue. According to our tests, the same issue appears when rendering with V-Ray.

Did you try with a Cinema4D internal engine scene? download an example scene from the content browser and give it a try..please.

I don't think Corona team already upgraded the installer, here is the dropped link from chaos support for ULA:

I deleted the ULA installation manually so I haven't yet tried to instal the new ULA...

here some WIP screenshots from our up-coming TV spot for an Italian company....Native Corona Renderer stills without external post production...

The ULA has been upgraded so the background issue has gone way. I got a message from Chaos support, you can download from chaos directly.

I already tried to stop the ULA background app and I didn’t get corona license on my computer without it. So I don't know if ULA is a component of the license server or something else.
These packages follow YOUR Corona render installer so I don't know where uninstall app is stored and also ULA is not an app but a user agent running into background started on Mac startup and scripted by a plist file with some rules inside.
Did you never seen the chaos cosmos and chaos license server folders? There are apps and executable files without icons into it in a total confusion, is impossible to understand where files are stored. Absolutely a total chaos!
So please, if Chaos is developing some apps without quality control is not a my problem.
I absolutely love Corona Render...but not Chaos Group app...

What is the point of sharing support answers on the forum? If you have some concerns, please discuss it with the support agent.

Please stop being disrespectful

Sorry about but this is not the right way to make support. What means “you can uninstall ULA from applications” answer? From where? Where is the uninstaller? There is not a uninstall app but only folders in a total confusion without icon with duplicated names and folder.

Right now is impossibile to work with this ULA background app that popup continuously into background...very disappointing...this issue is not only from ULA but from CBCservice too, cosmos browser.

If you want to delete my it without problem...
I’m a corona costumer “day one” with two licenses on my studio. If it were possible to pay corona render and not chaos group apps I would do it!
But don’t worry I will try by myself to find a solution.

I’m not here to disrespectful your job. As I said I love corona developers and I respect them for their jobs but chaos apps are a total disaster with a very bad development and quality control. I redirect tons of costumers to corona shop for buy it because we have a CGI school here in Italy, so we love corona render but the low quality of chaos service apps is very annoying.

Thanks anyway

this is the great Chaos Group support service:

It appears to be something new in Ventura OSX that has caused this issue. Until they release a fix you can uninstall the ULA from Applications.

Oh yeah, uninstall the ULA...and all problems will be cleared...🤦🏻‍♂️

A workaround is after rebooting the computer click into notification and at the preferences panel unflag the ULA and it’s stop for this session.
I have no words

Come on guys! Someone can Tell to Chaos developers to make something working with license server and cosmos browser on Osx system?
Here are tons of notifications on Ventura, due to a background services unrecognized as developer 😵‍💫
My god.

Same here on my MacBook Pro M1...The cosmos browser or the Chaos license server apps are absolutely the bad applications ever....I must disable it and login manually on the browser to get the license running...
Very disappointed....all has started by installing Ventura....

[C4D] General Discussion / Re: Speed on M1 Macs
« on: 2022-12-20, 18:26:18 »
Thank you Tom. Can you tell me roughly how much faster a MacBook M1 pro M1 max is compared to a MacBook pro Core i9?
I also believe that there is no difference in CPU between pro and max.
I'm sure many here would be interested to know what Corona'sg future with Apple looks like. After all, we don't want to spend money on machines that are hopelessly behind equally expensive Windows systems.

I work with a MacBook Pro M1 Pro Max. The Cinebench is 14.000, same as iMac i9 10K generation. Try a Cinebench on the MacBook Pro i9 so you can see yourself differences during rendering...
