Hello everyone.
This is another long technical one. I hope you like it nerdy, because this definitely is.
As we explore camera lenses to basically get better bokeh with the octane Universal Camera.
Thank you so much for all my existing patreons for your generosity!
And thank you very much for watching.
P.s. leave a comment if you have any good Idea for a future quick tip / tut.

I know these longer videos are tedious to make, but I want you to know that they are highly HIGHLY appreciated. All these in-depth videos are super interesting to watch. The educational aspect of your tutorials is what makes them so unique, specially the longer ones. It’s always a pleasure to get over a topic and pick something new.
Whenever you upload I always feel like we don’t deserve you, honestly :)
A magician never reveals his secrets. That’s what they say right?
Hey, thank you so much. That´s so nice to hear.
It was worth making this video for your comment alone 🙌
I guess a magician never reveals his tricks. But to the tricks there is another aspect. And this is practice. But I also get so much in return. Your great comment for example 😊
Cheers and thank you for your support!
Finally!
And holy shit. You've made that xpresso setup just to show the bokeh shape.? I don't know what to say. 🤯 I love you.
Ha ha yeah... finally 🙌
About the expresso 😇 I was thinking of ways to show it. Animating it in AE etc. This seemed the most efficient solution. Also because I could offer it to download so people have a helper at hand.
Nice tutorial!
3:00 - most beautiful lenses are triplets IMHO, modern examoles by meyer-optik-goerlitz. The less glass the better... more rendition, color saturation and micro-contrast. Well rendering wont deal with that anyway.
Thank you very much for your insights. Very interesting to hear that. Modern lenses seem to have a lot of glass. At least my Sony Zeiss lenses do 😇
But to be honest. I find them quite well performing.
Dude, the amount of effort you put into these tutorials for us designing the graphs and the mock scenes is unreal! Forever grateful 🙏
Thank you very much. Appreciate that you know how much work goes into making one of those ❤️
This Videos has navigated right into my heart💘
Not sure how this is possible. But great to hear that 😊
Cheers!
Really appreciate how you're educating us in an understandable but detailed manner. I'm learning instead of just mimicking here.
Thank you very much Eli. Appreciate to hear that its understandable. "Learning instead of Mimicking". This is a fantastic compliment 🙏🙏🙏
Awesome video Raf 🙌🏻
Thank you Ryan. Much appreciated!
after watching this, i felt like i didn't learn anything at all in my photography classes for 3 years
😅 Oh my, what have I done.
Thank you very much for your entertaining comment 😄
DUDE! This is the math class i needed in high school! the technical aspects of 3D are always amazing to learn!
Hey there. Thank you so much. Well I would argue its more of a physics class. But anyway happy you like it and learned something 🖖
40 minutes long.. oh yes! I’m grabbing the popcorn!
Ha ha ha I like that attitude. Keep it up!
Sadly I can´t make a 40 Min Vid every week 😇
Really appreciate you sharing some of the scene files. Always helpful for troubleshooting if I run into any problems while follwing along.
Hey James, thank you very much for your nice comment.
Those are just very basic files. But you are very welcome 🙌 🖖
men ! you are putting so much work in your vidéos ! that amazing !
really, thank you for you hard work !
ps : sad that the custom bokeh shape have so many bad side :(
Hey Atom,
super nice seeing a comment of yours again. Really nice to hear that you liked the tut 🙌
Yeah Custom Bokeh could be better. I think it misses a couple of sampling optimizations that could be implemented.
Hopefully we will get there in the future!
SLVRWNG men, you're by far the most amazing channel on youtube capable of explain and share so much great contenten not only for octane or CD4, but the science behind rendering. It's not like a tutorial on how to do something, you're are sharing the very meat behind the physics. I'm an enthusiast of motion, 3d and rendering, I'm always trying to learn things, grow my knowledge behind the process and you always are sharing in a way that could keep us excited to see your next video. Thank you so much for the effort, the compromise and the good will.
Hey there Rodrigo,
thank you very much for your great comment. That´s so nice hearing all that.
Happy I could give you some insight and be a small part in guiding your way as an artist.
Cheers and an awesome time to you,
Raphael
I am a blender user and I totally could relate it to blender options. Thank you. Really looking forward to getting better with Octane.
Thank you very much for your comment. That´s fantastic to hear. All the best and welcome to the octane club 😅 🙌
Brilliant! I learned so much and also re-learned things in a far easier way. Thank you, as always!
Hey Perry. Thank you so much for your great comment. Also for supporting me by becoming a Patreon 🙏
Really appreciate it 👏
wow, amazing!
Thank you very much. Glad you like it!
You sir are a technical encyclopedia.
Thank you very much Glyn.
Appreciate to hear that 🙌🙏
🔥🔥🔥🔥
🙏🙏🙏🙏 😁
Crazy that all this content is free. Thank you for this. But you could and should honestly make money with this
You are very welcome.
"But you could and should honestly make money with this"
This is why I have setup a patreon. This will not offer any additional content. But gives people the chance to give something back if they want to. I hope one Day it will be enough for me to make a living.
Great tip! We should have a focusing day, May the 2nd, The Focusing day :D
Ha ha ha ha. Lets make Focusing Day a thing 🥳
u just got a new subscriber
Thank you very much Micheal. Much appreciated 🙌
INCREDIBLE Tutorial Raph. My God. I'm opening a Patreon account as we speak.
Maybe you can do a small quick tip about the bokeh in anamorphic lenses next.
And once again, incredible. Thank you so much.
Hey Arenas, thank you very much for your comment and your support on Patreon. That´s awesome!
Also thank you for your suggestion. True Anamorphic Bokeh would indeed be rather interesting. I would have to do some research first though. I will write it down on my list 🙌
Watched it without coffee! Very nice
Thank you very much. Much appreciated!
It´s of course also allowed to be watched without coffee... On your own risk 😄
thank you very much!!! nerdic degree achived!)))) split-focus something that I've never heard about, very interesting! Still I'm looking forward to watching a tutorial about volumes! thank you very much, your tutorials are outstanding
Hi there and thank you for your nice comment.
Split focus diopters are a real thing that have been used mostly in older films. Basically those are cut in half screw on lenses that give you a different focal point for half of the image. If you google it, you probably see examples.
Thank you also for your suggestion. As volumes are a really complicated subject (as you know) and therefore a tut would cost quite some time to produce I am shying away from the idea right now.
Maybe you will get lucky in the long run 😇
Thank you so much man, super helpful!
Thank you SilverwingVFX!!!!! like always!!
You are very welcome!
Very nice tutorial. Thank you Raphael.
Very nice seeing you here Jochen.
Thank you very much for your kind words. Glad you like it 🙌
Hello Raphael, you mentioned about the new ideas for future videos, i dont know anybody asked about that but i'd like to know about your lighting process, usage of both hdri and scene lights. Different lighting for different materials, etc. Thanks!
Hey, thank you very much for your comment and suggestion.
Generally my lighting setups are shockingly simple. I will write it down on my list. Might actually be a good idea for a Quick-Tip!
@@SilverwingVFX Thank you very much! Your tutorials are the best! I am studying them as a 3D student 😅
@@gumustas Thanks so much. All the best for your studies and happy learning 🙌
whenever I see your videos, I like them as soon as click on them, because I know I'll find lots of valuable knowledge, thank you 🙏🙏
Ha ha ha thanks a lot. I hope this always holds true and you find at least something useful in those now as well as in the future 👍
@@SilverwingVFX it's been the case for years hahaha so yeah 😂
ty
You are very welcome 🖖
Hello Silverwing, do you know which is the earliest Octane version that has this Universal Camera? I only use perpetual licenses because subscriptions are too much risk. but not sure if there is a perpetual that has this camera type (or at least aparture maps)
Hey hey.
Thank you very much for your comment and your question.
The Universal Camera came into Octane in release 2020.1
It was however somewhat usable before that as an OSL camera. But not with all the features that I show in the video above.
Hope this helps 🙌
P.s. I would also prefer to go back into a world with perpetual licenses 😊
@@SilverwingVFX ok, thanks! Yes, we should advocate perpetual softwares more often. and also speak out against subscriptions as an only option. Or report more often at consumer protections etc. about such and more consumer related subscription ripoff.
great work. love the notched look. Looks like there is interesting uses for some light kaleidoscope effects with high values. I wonder can you have the C4d Camera deformer act on this? or is it further down the stack of operations?
Thank you very much for your nice comment and your question.
Unfortunately for now, all the settings of the Circular, Polygonal and Noteched Aperture are hard coded to the camera shading system. So no way to apply any changed outside of the already existing possibilities.
If you know programming, you can write your own camera in octane though. Therefore we have the OSL camera preset!
I´d totally watch an entire camera settings walkthrough
Ha ha that´s a nice compliment. But would be sooo much work to do 😅
Thank you for these tutorial videos. What I want to learn is: Which lens is closest to the human eye in cinema 4D? Based on my own experience, I use the sensor size as 70 mm Focal Length and 50 mm. Do you think this is true? According to my research no one changes the sensor size. Thank you!
Hey Muartive, thank you very much for your comment!
About your question. Hmmmm I honestly have no idea. The saying is that with 35mm sensor, the closest would be 50mm. But some say it is wider, more like 35mm. I actually did not think about it to much to be honest.
About sensor size. I at least never change it. In general everything that can be done with a 70mm sensor, can also be done with a 35mm sensor. The numbers for the focal length and f-stop are just different. In real world bigger sensors have a wider FOV on the same focal length and shallower depth of field.
Amazing, love the detail you go into! I had a question regarding anamorphic lens, is this possible to mimic in C4D?
Are you talking about the C4D Physical Camera?
Yes you can use the "Anisotropy" setting in the "Diaphragm" settings for that.
Hope that´s what you wanted to know. If now feel free to further explain.
awesome as always Raf . can you do some scenes breakdown please ?
Hey and thanks for your kind words and the suggestion. I may do that in the future 🙌
Hey, this is great. One issue I am having is that when I switch to Universal camera then live viewer becomes quite slow. Is this normal?
Hey hey, thank you very much for your comment!
Depending what you are doing rendering with universal camera is slower. Using custom bokeh shapes is super slow (you also notice that the scene becomes more unresponsive.
Also I noticed when you switch back and forth between a thinlens camera and an universal camera the scene might become laggy for about 30 seconds and then responsive again.
If you have a somewhat decent GPU and your scene become super laggy / slow, that is definitely not expected!
i was wondering how could i simulate aperture rotation like helios 44-2 lenses, do you have any tips on that?
Thank you very much for your question. I am guessing you are talking about the so called swirly bokeh?
I think a combination of settings might come close. Definitely a combination of Optical Vignetting, Cola, Spherical Aberration and maybe some Astigmatism.
You probably won´t get the exact effect but, you can definitely get some swirly bokeh... Sorry I am not able to give you some formula or something. Usually its the mix of understanding the settings (which this video should at least make more easy) and then researching the "flaws" of the original lense that gives it its characteristic.
@@SilverwingVFX you just gave me the most practical answer, the flaws is what i have to look out for! Thanks again for everything.
Your tutorials are gold. Extremely helpful.
That´s super awesome to hear 👏 Thanks so much 🙌
Another very nice totorial! I still in search to find a realistic way to do an anamorphic lens with distortion in Octane without having to put a "fake lens object" in front of the camera... If you have any idea? Peace!
Thank you. I much appreciate your kind words.
What are you looking for in an anamorphic lens?
The most simple way would be (as I mentioned in the video) to just squeeze the bokeh shape. I say in the video that the factor is 2. But after studying a bit more, this might not be right. I have to do the math on it.
@@SilverwingVFX Haha You will understand what I mean., I actually found a nice technique in a interview for blender... But don't know I to do it with c4d octane. ruclips.net/video/Eeh8crvsqbA/видео.html (Go at 52:08)
@@learn2share461 Thank you for the link. I think I get what you mean.
So its a basically a barrel distortion that only takes place on the horizontal axis of a frame. The vertical axis is barely or not distorted.
You can pretty much do the same effect in octane when choosing the panoramic camera. But you have to type in those numbers by hand. There is no focal length there.
If you want the nice Bokeh of the Universal Camera, you would have to use lens distortion maps. Those are the same as saved out Texture Coordinate (UV coordinate) maps.
So what you could do is take a 16:9 3D plane. Distort it in the fashion you like. Point your camera straight on the plane, so it shows the mostly everything (minus the parts that were barrel distorted above and below the frame. Then render a Texture Coordinate of that (best use 16bit or even linear exr) Then load it in as your distortion texture.
I made a distortion map creation scene using a FFD deformer and linked it to the description. As well as a file showcasing how to apply it.
If you have any questions about it, let me know.
Hope this helps.
@@SilverwingVFX You are very nice to take the time to give all this informations. I will keep you in touch of my test.
