Well, first, I'm not really that technical, so cpu, gpu, such and such, no idea.

Second, I have a lot of versions of cinema4d, but at the moment, I'm very happy with R18. I've had a lot of problems with R19, crashed lots of times. Superlame. R20, with it's new material node system, completely new to me, so have to find some time to learn..

Third, time! I don't have any time to really get into it and do some tests and experiment =(

And lastely, I'm not sure if it's my computer or my ability to get something good (Probably both =D), but it doesn't render that fast..

 

Is it THAT good, gpu rendering?

 

haha... amusing and at the same time very lovely answer...

just to give you an idea: you could have rendered that image with redshift or octane for instance about 20x faster on a single nvidia gtx1080ti. that's no exaggeration, it's really that much faster. plus, you have an ipr where you can immediately see any changes you make to materials or camera position or lighting and so on... which means not only rendering is 10 to 50x faster (depends on the specifics of your project), the look dev process speeds up by roughly the same... so any time and money you invest, you'll get back after the first couple of projects. i really couldn't imagine a life without redshift anymore, it's just so much more fun to see changes immediately, also it saves a lot of money in rendering.

 

edit: that image would have probably rendered in around 4 to 5 minutes in redshift. you also would have gotten nicer looking sss and it renders c4d hair natively.

    Ah yes. Nvidia. I have an iMac Pro, with an AMD Radeon Pro Vega 64 16Gb card.. Would that work?

    4 to 5 minutes in redshift? Versus 14h (on my old Mac Pro by the way!) physical? That's a HUGE difference! :O

    I agree with Everfresh - though don't rule out better CPU engines on older Mac hardware.  Take a look at Corona.  Easy interface - integrated much like native Cinema and will still run on a CPU and give you almost real time feedback with an IPR.  Not to say that Octane and Redshift aren't awesome - they are, but CPU engines have evolved past Physical too.

    with a mac it's a little bit more tricky. i know because i'm on a mac, too... to be able to use redshift or octane you would have to buy a thunderbolt e-gpu enclosure and a good nvidia card. then you will have to run a script once via terminal to make your mac recognize the external card. does only work up to high sierra, there's no nvidia drivers for mojave (yet). by far not an ideal solution, but still better than having to wait 14 hours for a render that you could have had in 5 minutes. 

     

    if that sounds too complicated to you (it really isn't that complicated), i recommend to try corona, which is cpu only, but still very fast. not as fast as redshift or octane, but still like 5 to 10x faster than physical. also a bit more easy and intuitive to use than redshift for instance. then there's also cycles, which is gpu and cpu, and also vendor agnostic, so it also runs with amd cards.

    can't say anything how it performs on amd cards though since i never used it. but just download the demos for cycles and corona and compare which works better with your setup.

     

    btw, redshift, cycles and octane have purely node based materials, while corona has a layer system ( @EAlexander: corona does have an optional node editor as well now, doesn't it? )

  • I read about those eGPU's yesterday, and also read about that script via terminal. They did say you should make a back up of everything, just in case. A bit scary, as I have a pretty constant flow of commissioned jobs. And I run Mojave, but I reckon there will be Nvidia drivers pretty quickly for that.

     

    And this was a personal project, so time didn't really matter. That's why I rendered it on my old Mac on the side, so I could continue working on my new Mac. For commercial projects I try to keep the render times as low as possible, and if it's too much, I use a render farm instead. This works great, but like you said earlier, it costs me money, and download time.

     

    Which would be the best Nvidia card to have? There are so many!

     

    I'll have a look at corona too! Thanks for all the tips and info guys! =D

    and that's the huge difference... with a render engine like redshift you don't have to worry too much about render times, and if you should use GI or not... you just always use GI, since it basically comes for free. and flicker free ;) also you can use insane amounts of sub-poly displacement without the insane preparation and render times c4ds native material system has. for commercial work i also always render via online render farm, but it's just much cheaper if a frame renders in a couple of minutes opposed to a couple of hours. and you can still charge the client the same. basically all the bigger render farms support redshift by now, but be aware that this is not the case with octane, due to its licensing policy.

     

    regarding the best nvidia card for gpu rendering: i suppose it's the 2080 now, but a 1080ti will serve you well enough.

     

    regarding backups: i hope you do regular backups anyways ;) i know many people who ran the script to use their egpus, and i've never heard of any issues with it, so you're most likely going to be fine.

    Awesome! I'll have a look at it. I've heard many good things about redshift (my agent was also bragging about it) so maybe it's time to jump on the wagon ^^

    Guess I just have to wait a bit when there are drivers for Mojave..

     

    As for backups: of course I make backups =D But it's always lame to go back to a previously saved thing, and trying to find everything back.

    oh yes, always NICE to hear such kind words straight in the ear of Mac-Mini user ::):

    I fear that there may NEVER be drivers for Mojave.  I read an article suggesting that relations between Apple and Nvidia were so bitter that there were no plans for it.  Apple has to approve any drivers Nvidia creates, so they are at Apple's mercy.  One can only put off upgrading the OS for so long...

    I moved to PC over a year ago mostly because Apple had pretty much abandoned it's pro users.  Remember when they released a "new" Mac Pro with no room to upgrade anything internally - over 5 years ago?!?  Yes, they say they are launching a new Mac Pro this year, but I'm not holding my breath.  I love the OS - switching to Windows was painful- but I just didn't see a future in 3D with Apple.

    Yes, you can either use the node editor or build matials the tradional way now (similar to Octane), but the traditional way is very well intigrated into Cinema. Corona uses native procedural noise, Fresnel and other shaders.
