adding second order spectrum is really easy on this. Nice setup. The best I have come across so far. Cinema 4D´s physical renderer allows for individual normal maps per reflection layer as well. This should be adaptable with some tinkering
CG-community is about to get so many CD renders, it will be enough for us to set up a new CD-store (at least digitally) :)
As always, extremely gorgeous render, Raphael! You don't fail to impress. Your shading skills are just impeccable!
Ha ha ha. Would be awesome to see it catching on creating a trend. To be honest I am still surprised how many people like the CD. Seems like I was lucky with my choice.
Thank you again for your support. Much appreciate your kind words!
Great stuff, I can't wait to give it a try to replicate it in 3dsMax + V-Ray!
Thank you!
Oh nice. Looking forward to it. Keep us up to date!
1:19 "..with Limited knowledge.."You are the Octane Guru.. But a Guru is always humble.. Amazing Content once again!!!
Thanks so much. You are too kind ❤ I appreciate it very much!
OMG, I'm so glad this worked out in Corona as well! Thanks Raphael! This is an amazing technique
Awesome to hear that it worked for you 🙌✨
Big thanks! Im not using Octane, but could understand how the effect works with your help and recreate kinda similar thing in Redshift
Yay, that´s fantastic. Glad you made it and could use it on RS now 🙌
That´s the good thing with my videos. They are usually pretty universal, so they can be applied to a lot of other render engines!
i liked this video as soon as I clicked on it, I knew it'll be a treat, hahaha I missed chart time, thank you for putting this together, wish you a productive week ahead 🌟🌈
With such a comment there is no other way then to have a good start into the week ha ha. Great to hear you like chart time 📈 and of course liked it overall! Cheers and thank you for your support!
Thanx Man, as usual your chanel is litteraly a gold mine !
Hey hey. Thanks so much. Phantastic to hear that 🙌
The maestro is back with a banger. Not only octane, Your C4D Xpresso setups always amaze me. Can you do more tutorials on Xpresso pleeeease? 🙏
Thank you very much for your nice words and your request.
I love Xpresso and would do more videos. Unfortunately we are in the minority as it seems 😇
Hope I can do one every now and then though.
LOVE. Thank you. Love the detail you went to. Enjoyed the physics lesson too. 🤓🌈
Thank you very much Tristan.
Glad you enjoyed both the physics and the shading 🙌
I personally love when both go hand in hand!
Insane, is awesome how you achieved the result via all the investigation on how it really works. Thanks for sharing.
Thanks so much. Yeah I love using physics as a pillar 🙌
You are the first youtuber I'm seriously considering supporting on patreon. Love your work good sir. 🌈🌈🌈🌈🌈🌈
Thank you so much. Super great to hear that.
Please only do it if you can afford and really want to. I appreciate your support here writing comments 🙌
@@SilverwingVFX Seeing as your work here has helped me do my own work, it's the very least I can do to support. Thanks again.Looking forward to the next one.
🌈 Amazing tutorial, Raphael!! 🌈
Thanks for this breakdown! Love to see this level of model representation and simplification for abstracting complex reality behavior!
Keep it real!
Hey Fernando.
Thank you once again for your comment and your support. Much appreciate it!
Cheers and a great start into this week to you!
Wow insane complexity - genius at work
Thanks so much ❤️
Thank you very much for all the knowledge you're giving, really helpful for many of us !
Such a "simple" yet clever solution to make it works like real life 🔥
So cool to read this. Thank you very much.
I predict a lot of disc project in the following weeks 😅
Super in-depth technical breakdown! Thanks Raphael! 💿🌈
Yaaay thanks a lot 🌈 Much appreciated.
this is much better than my way of recreate this, which is too noise and heavy. Thank you so much for sharing to our community
Thanks so much. Glad you find it useful 🙌
It might be still render long-ish. As calculating all those materials is not too trivial... but the look makes up for it!
Excellent stuff as usual
Thank you Omar. Much appreciated 🙌
Crazy ...!
Ha ha thanks. I hope crazy in a good way 😇 😄
Are you even a human? This is a mindfu** 💀👑
Ha ha ha. I can assure you I am all to human. This is the only thing I am really good at 😅 😇
LEGEND
🥰 Thank you!
Brilliant as usual!
Thank you so much 🙌
Interesting !
🙏💿
golden informations. thanx for effort
Thank you very much. Glad to hear that 🙌
🌈Huge Thanks)
You are very welcome. And thank you for your dedicated viewing routine 🌈 🙌
thanks for this raphael
You are very welcome Paddy 🙌
absolutely insane, thank you for such another masterpiece 🌈❤
Thank you so much Yassin. Also for being a loyal patreon!
Means a lot 🌈💿
Great tutorial!
Thank you. Much appreciated 🙌✨
Thank you!
You´re welcome 🙌
This is the most realistic CD shader I have ever seen .
Now that is a huge compliment. Thank you very much 🙇♂💿
AMAZING TUTORIAL!!THANK YOU
Thanks so much. Appreciate that you liked this video 🙏🙌
Wow this is one of the biggest contributions to the VFX / 3D community I can think of. Amazing breakdown of the process and engineering of the material. A legendary milestone in terms of content. I am certain pros and novices alike will be using this as a basis for many creations to come. Also tutors should not miss this! I suppose it's quite obvious how excited i am lol
Hey hey.
Thanks so much for the long message. Super nice to see that you are exited about it. Not sure if it´s a legendary milestone. No doubt its useful for artists who want to shade a disc though 🙌
@@SilverwingVFX welp it will be legendary in many ways I think hehehe 🤭 definitely a huge step up for those who will apply this to their process!
Very impressive tutorial! 👏 🙏
Hey, I am very happy to hear that. Thank you very much Michael ✨
🔥🔥🔥🔥
✨💿✨💿
Love it! Looks amazing. Thank you!🧠🌈
Thanks so much Zotake. Really appreciate it 🌈
🌈
Thaaank youuuu 🙌
I'm late to the party but amazed as always, thanks Master!
🌈🌈
Thank you Emanuel!
Highly appreciate your kind words and watching it all. Ha ha thanks for the effort with the rainbow. I had the same Idea, but also was stuck reversing it 😇 So I leave it to imagination ☀💦
lets gooooooooooooooo
✨💿✨
🤯🤯🤯
Yaaay. Achievement unlocked. Very nice seeing you here 👑
Very cool! Is this the same way the holographic foils work? Have you tried using different patterns to adjust the angles of refraction? I think this is worth a separate tutorial
Hey thank you very much for your comment.
I have thought about it but was pretty busy getting this tut out. I definitely want to try something like this when I find some time!
I've been wanting to create holographic foil for years now, and with this GEM of a tutorial I have finally got a foundation to work with, I will definitely try to work on my own shader for holographic foil based on the amazing research and work Raphael did with this
Always the boss ! What do you think about lenticular effect like you are looking to the right and left you have a different image shown. Or may be laser holographic (image with depth and usually red and green color reflexion) i will send you references on instagram
Thank you very much.
Actually my first implementation of this went along the lenticular effect route. Showing different colors to the camera based on a wave pattern on the surface. but I scrapped that since it was very noisy to render 😇
Yes please send references. I am always interested in seeing what´s out there 💪
maaaan thats amazinhg, but i just noticed that the color interface changes all the game here, i was used to get the c4d native color GUI type, and the color values was always broken when i try to do that.. wow! everything was working agter changing it to the octane one.. maybe there some color correction when using it.. damnn
Thank you so much Marcus.
Hm. Interesting observation with the colors in the C4D Interface. I think C4D is Gamma 2.2 and Octane is linear. But still values of 0 and 1 should be the same.
Maybe I need to make some tests. Phantastic to hear you got it to work at the end 🙌💿
@@SilverwingVFX I've tried to use the color correction node, but Im it doesn't work on normal channel.. Then I tried to roll back to the octane GUI, they are really different output values, setting the rgb as 127 on c4d they were around 0.2 on the octane picker
@@MarcusRizzo Ah, that´s what you mean. Yes. Normal Maps need technical unaltered values (in other words linear)
If you put in 128 in C4D and then use a color correction with gamma 2.2 it should work technically. Habe not tried it though.
But the good thing is that you managed to get there in the end 🙌
Very impressive backward engineering. I got the same result using the Ai node and typed in 'CD shader' although the label wasnt Windows 95 - It was Radiohead-In Rainbows. :)
Thank you very much. Backwards engineering is great if it works 😅
Radiohead is also a great choice if you ask me 🙌
🌈⛅✨
Yaaay, thanks so much. Hope you liked it. Also your name in the credits 🙇♂ 🙌
@@SilverwingVFX yaaaasss! Loved the mention haha it reads so well on screen 😇 made me chuckle with joy! 🥰
🌈💿
Yessss. Thank you so much for 🌈 the video. Much appreciated 🙌
I wonder did my post on Octane Render group with Diffraction Granting hint you towards that? The layout and method is exactly the same lol
Hey there. I indeed saw your post while doing research. But I did not realize my approach was that close 😇
I remember watching your results some Days before I started working on mine. So there is definitely some inspiration in there.
It´s interesting that they are so similar as I did not pay that much attention to the nodes back then and when it came to the node creation process just tried solve it in the most efficient way. I had another method in place first that applied grooves. But that was really noisy to render. So I ended up with the method in the video. Must be a good method if we both landed on the same conclusion! So thanks for your work and inspiration!
Is that possible to re-create the same shader in Redshift?
Hi Fedor,
yes, definitely! Instead of adjusting the normal maps strength you have to use the Bum nodes strength set to "Tangent Space Normal".
Getting the Anisotropy to work right is also different in any render engine. I noticed that checking "Use Tangent Channel" in the material that utilized the Anisotropy in RS gives you better control. I can´t tell you how to get the gradient right so you get a circular anisotropy.
Other then that it should be pretty much the same as in octane.
All the best. Would love if you´d let us know if you succeeded!
Cheers,
Raphael
@@SilverwingVFX Thanks for the answer, really helpful!
I tried to rebulid it but faced the problem with material layering. Redshift doesn't have that "material layers" feature. I stacked a couple of materials together with Material Layer, but seems like you can't layer more than 5 materials (and we need 7) :(
🌈🌈🌈🌈🌈🌈
Ha ha ha ha ha. Does that mean you have seen it 6 times whole 😁
Anyway thank you very much for your support. Much appreciated!
Thank you so much for this! I've been waiting for years to find this solution 🥹 you're a legend 🌈
Thanks so much. Those comments make me get up in the morning and spend editing tutorials on weekends 💪
