[C4D] Daily Builds / Strange configuration of materials in objects downloaded in Chaos Cosmos update

« on: 2025-05-29, 16:56:41 »

With the april update of Chaos Cosmos with the release of the latest version of corona c4d macOS, chaos cosmos objects are downloaded with a canl of SSS material that makes render times increase a little bit (actually it increases a lot the pre-calculation and the render only a little bit in print) and the interactive render times increase a lot, being impossible to use it.
I have made a comparison with the same objects downloaded 1 month ago, and the same old object does not have the SSS channel in the materials and the same object downloaded now has it. This has happened to me in a scene with several vegetation objects and the scene has become almost impossible to handle with interactive renders.
I think it's due to a bug and it's activating this channel in materials that don't need it. I have tried to go object by object and material by material deactivating this SSS channel and when I do this exercise cinema 4d closes with an error in the corona plugin.
Is it possible that this is a bug and not a problem with my equipment?
My computer is macOS 15.4 Studio M1 Ultra. I have tried it on other computers and the result is unfortunately the same.
I hope you can help me.
Thanks for the support and this wonderful render engine, thanks for not forgetting the macOS users.
Suggestion: study the options of implementing rendering through chaos cloud. Chaos Vantage for macOS.

[C4D] Bug Reporting / Re: LegacyVRayShader

Some old vray stuff converted to corona.
I don't know how to locate the material that channel has, because there are several models and materials that I have in the scene. Is there a method in cinema 4d to locate it?

[C4D] Bug Reporting / LegacyVRayShader

« on: 2024-04-19, 17:18:01 »

Cinema 4d starts some crown models with this message:

Several plugins used in this project are missing.
Saving may result in loss of plugin data
Plugin 'LegacyVRayShader' (ID 1026701)

How can I locate this reference to vray? I don't have vray, I only use corona. But I get this message with some objects. Can I identify the material in some way so I can delete it?

[C4D] Daily Builds / Re: Corona Render Test M1 and M1 Max

Yes those numbers do look about right according to the internet! 20 core Ultra makes sense as my 10 core M1Max MBP scored just short of 12000 pts.

So I was expecting more of the i9 but maybe my logic is off - but in turn that does make the Corona results odd too.

That is why I insist, there is something that does not fit me and I think that we can do something to improve or help.

@Chules - just wondering - you haven't accidentally limited the number of cores on the i9 Cinebench in the preferences have you? (Something I've done before!)

To the best of my knowledge, I believe that I am performing the test correctly and there are other people with the same results. Attached screenshot of the test. When you perform the test, 20 buckets can be viewed. This same test in mac Studio yields a score of 24,000 points compared to 13,000 for the iMac i9 10C/20T.
Value you, I speak from limited knowledge in terms of hardware.

I agree on the Cinebench - that doesn't make a lot of sense!

According to Embree on its website, it says that both cinema 4d and corona use the Intel® Embree library. It seems that previous versions were already prepared for apple silicon. There is a new version, but I don't understand if it has optimizations for apple. Do you think that this is where the optimization can be to improve something? If so, I can't know, I still don't understand the results I get with the native render of cinema 4d. This is the point that makes me doubt that we can have better rendering times on apple silicon. Thank you so much.

At the end of the day a 10core iMac (20 threads) i9 has much higher speed base clocks than the 20 core Ultra - so there I would expect the i9 to win in certain tasks - and also the Intel Embree rendering libraries that had to be converted to work on Apple Silicon are no doubt still in their early stages of optimisation - so I think there are still things going on/ being developed.

Thanks for your comment. The way you explain it, I understand it very well and what you say makes a lot of sense. But... why when I run the cinebench test on multicore is the mac Studio almost twice as fast as the iMac i9? Shouldn't it be logical that something similar would happen with a crown? Is it possible that when those libraries are ported to apple silicon, Corona will return results that are more similar to those of the native cinema 4d engine? I'm just trying to help and see what limits can be reached with these processors and this rendering engine.

I would like to add that I am trying to pass this matter on to the apple developers to see if they can provide some help on this issue.

First of all, I would like to thank the developers and the corona team because thanks to this rendering engine my work is easier and the results are very popular in my infoarchitecture area. I am a mac user, and I have renewed my equipment. I currently have the latest iMac i9 128GB that apple makes with an intel processor... it works great, I've had it for two years and both cinema 4d and corona work perfectly. I have acquired a mac Studio M1 ultra and it is incredible how cinema 4d, photoshop, illustrator works... a performance improvement is very noticeable when it comes to processing, saving, executing files and plugins. Cinema 4d moves wonderfully, everything is much more fluid. When rendering with corona I only see a slight speed around 10%-15% faster than the mac Studio M1 Ultra compared to the latest model iMac i9. However, Cinebench and Geekbench benchmarks show that the mac Studio is almost twice as powerful as the iMac i9. When I render with corona, that difference is not seen, but when I render with the native cinema engine, yes. I have selected a movie scene and I have rendered it with the iMac and with the mac Studio. The iMac returns a time of 8min-48sec and the mac Studio a time of 4min-56sec. I have a lot of trust in the Corona team and you are the ones who have more information than us. We do not question your work, quite the contrary, we appreciate all the news and corona operation. I just want to add that after several tests I have the feeling that the optimization so that Corona is native in Apple Silicon processors is not being able to take advantage of all the performance of these processors. I can guarantee you that these processors are wonderful because I have 3 different computers with apple silicon and both in 3d and in graphic design I have noticed a great performance improvement in the software I use. I just want to ask you to give this topic one more review and tell us how we can help. Possibly we have to talk to Apple to help us all, because there is some concept of this transition that we are forgetting. I am going to continue using corona because I feel very comfortable with the render engine and cinema 4d, I also feel more comfortable on my mac computers than on windows. My plans are to acquire the third corona license because I want to expand the workforce, but what would make me happier is that this issue be studied again in case there is the possibility of improving the performance of corona render when rendering and taking advantage of all the power of apple silicon. Thank you very much for everything and best regards.

[C4D] Daily Builds / Re: Mac M1 LOW POWER MODE bug lives on.

« on: 2023-02-09, 19:33:37 »

I have done many tests and always the Mac Book Pro M1 Max was much slower than the iMac i9. Always the M1 Max rendered at an average of 750-800% and the iMac i9 at 950%. Apparently, the M1 with better ventilation do not have the %CPU drop problem... I have raised the Mac Book Pro from the work surface leaving the lower central space free and cool and the render times have improved... it takes 1 hour with an average of 950% CPU. I'm doing long-term render tests and I'm buying it with iMac i9 and it's starting to improve a lot in performance. A little below the M1 Max. When I carry out more tests I will be able to throw a percentage or comparative times. I hope I can shed some light on this matter because my workflow is mac and corona and I am so comfortable that I would not want to change it. From what I read, the mac studio does not have this performance drop and it seems to be a very powerful processor. I have the problem on an iMac M1 that I don't know what I can do to improve its cooling or CPU performance. Thanks to all users and the corona team. Thank you for bringing this wonderful rendering engine to mac. A greeting from Spain.

On my Mac studio Ultra with 128Gb all works as it should, all cores fully on close to 2000% with all night renders.  I think the performance problems are realated to Macbooks.
Interesting to know if the new M2 Macbooks pro max have these issues as well. I was thinking of getting a Macbook pro max with 96Gb but if rendering slows back to a throttled mode its a waist of money.

Thanks for the information. This week I'm going to order the mac studio!!! I love the infographics and homes you have on your website. All the best.

@Chules There is a large thread somewhere about this performance issue for the new Macs. I thought i remember someone mentioning some type of workaround to get the performance up, but can't remember exactly. Curious if you install an app like Macs Fan Control so you can monitor the temperature. Does the slowdown happen when a certain temp is reached, or is the slowdown a preventative based on the load?

What happen if you have a fan blowing on it or run it in a cold room? Does that keep the temps down and does that affect the temps?

Thanks for the suggestion. I will test and tell you the results. All the best.

Good morning. I'm having performance issues with a mac book pro M1 max and an imac M1. It seems to be according to the corona department that the performance drop problem is due to the ventilation system of the equipment. The activity monitor shows a % CPU of 750% when rendering when on mac intel it shows 990%. The fact is that I see that the M1 Max is much more powerful in certain tasks than the last iMac i9 but when it comes to rendering complex scenes the M1 Max is below the i9. I am going to buy a Mac Studio Ultra 128Gb, ​​my question is if you are observing that when rendering it is not taking advantage of all the power or, on the contrary, the mac studio takes advantage of all the potential when rendering with corona. The developers of corona comment that they work with a mac mini that in their opinion has better ventilation, and their tests with corona show that corona works at 990% when rendering. They say that they have done tests with Mac book pro and that the performance also drops to 750%, and their reports say that it is the mac book pro itself that prevents excess heat and lowers performance. I would like to know if I am right to buy mac studio and if you can verify that the ventilation design in mac studio is better and does not cause a %CPU performance drop when rendering. I take this opportunity to congratulate you on your 3d infographics and projects. I have a scene that I've been testing so I can buy the i9 vs M1 Max. Thank you for your attention and I hope I don't take up too much of your time. A greeting from Spain.

Hi there, are you able to share a test scene for us? I am not able to reproduce this. Thanks in advance.

I have verified that the error comes when the light is inside a subdivision container. In corona 8 it does render the light inside a subdivision container and in corona 9 it does not render. In corona 9, I pull the light out of the container and if it renders. It is not common to put a light in a subdivision container, but it had been the case.
