In this C4D tutorial you'll lean how to create physically accurate metal surfaces in Redshift, by using the Advanced IOR technique. I've shown how to do this for Octane early on the channel, and now it's time for Redshift as well! And as a bonus, we'll explore how to make procedural imperfections and scratches, to give our metal a realistic, scuffed look.

man we need more redshift
Yeah I'll probably introduce more Redshift into my workflow!
Woah, New Plastic on Redshift? You love to see it
Who woulda thunk it
With just a single tutorial you're already dropping serious node knowledge on the Redshift community. Always loved your Octane videos and after switching over to Redshift I've fallen behind on your content unfortunately. Nobody gets down to the nitty-gritty of surface imperfections like you do. Please make more Redshift stuff!
Yeah it's trickier with Redshift because its node system is much more basic and limited than Octane's. But I'm trying to push it the furthest I can. I'm learning more as Igo! Will share more stuff soon
Wooooow redshift tutorials finallllytt
Yessir! We'e still Octane babies but Redshift can get some
Thanks for using Redshift!
I love your Octane Tutorials but I had to switch to Redshift because every of my agencies uses Redshift so I very much look forward to more Redshift tutorials in the future.
Yeah I think it's important to know your way around as many platforms as possible, they all have different strengths and I think Redshift has a lot of (unfulfilled, yet) potential since it's owned by Maxon. So I was just curious to finally see what it can do. Octane is still king tho.
same, only redshift in the pipeline
Time has come. We are going to have Redshift packs
I'm excited for this too!
Haha yeah I've been neglecting Redshift for a long long time but it's finally time.
oh my god, REDSHIFT COMING!!!
Coming in hot!
want to use Agx in redshift 😢 is it not available yet? I can not find way...
Damn, this is one of the best and most informative redshift material tutorial I've ever seen and its just your first one. Cant wait for more. Thanks!
Thank you sir, more coming up!
New Plastic redshift tutorials?? Am I dreaming 🥹
Haha it's a nightmare buddy wake up
Wow, man, i feel you in process! So much fun and learned so much new technique about Noise and how deep you can dive in to it. Thanks a lot 🎉
Redshift finally!! That’s great..can’t wait to see more stuff made with RS 💪💪💪
Yup, me too, I'm already working on few
This is Brutal, thank you for the tutorial.
Love Redshift! Great video, dude! 🥳 X
Thanks jakejakejakejakajeakjakejkajekae
Wow, masterclass
Finally Redshift. Stunning.
Yessir!
bravo dude!
More Redshift, please! Love your content!
Hehe it's coming
"Hey look at this cool animation, it's done with OCTANE! So let's get to it on Redshift"...
i'm so sad because i don't have redshift... but amazing video !
Welp, you're not missing a lot. Stick to Octane my boy!
Yooooo redshift!
Had to give it some love
muy chulo
ayee orale
wow great tutorial thanks. Quick question....in the intro with the spinning rings, the second ring has a kind of oxidisation in the grooves. Will you be making a tutorial on how to do this?
More Redshift!!!! I love your octane tutorials but every job or client uses redshift now for hand offs and are to scared to shift into anything else :/
That's wild, Octane is better in almost every way. But Redshift comes with the full Maxon pack so I guess it makes sense to work with it. That's why I started to mess with it because I already had it installed so I figured I should give it a go.
@@NewPlastic Its mainly that, its in every studio. A lot of freelance clients come with a half backed redshift idea and want to keep it within that pipeline, not for any reason other than thats what it started in... I think Redshift is just pushed by maxon. I don't know if one is better!
Wow this is soooo helpful thank you so much for the tutorial! This might be a dumb question but how do you save the material in the asset broswer?
No stupid questions. If I'm not mistaken you just drag it into the folder you want it to be in. That's it!
I love everything you do! I study and repeat after you, the result is just bombing❤ I ask you to make a video about the rendering of jewelry with diamonds. How can you do it?😊
Redshift or Octane?
If you're doing a glass-like material with refraction I've found that Octane actually has some easier ways to tweak the level of refraction in a predictable way. RS seems to have major color shifts the more you try to art direct the refraction. There's a few good tutorials on youtube that cover glass refraction that will probably get you pretty close though. The rest of it is lighting and building your mesh so it displays impoerfections/etc. correctly.
@@spenserwilliams5515 Nice! I'm working on a professional stage lighting with a ring, now I'll try the octane work)
Welp there you go, Spenser probably knows more than me. I can say that so far, Octane looks better in a lot of ways. There's something more sophisticated in the way Octane handles light and materials.
Thank You very much! Is there a chance you could create these cool libraries for Houdini?
Thank you!
Where did you get the RGB wavelength for gold from?
thanks again.
had to switch from Octane to Redshift but I totally love your work, please do more Redshift stuff there are way too less good redshift material tutorials!!
Well, there's a reason for that. Redshift is pretty weak when it comes to pushing the node system, compared to Octane. And since Redshift is slower than Octane, the slower response time for render updates when you mess around with the node system is seriously exhausting, so it's hard to just keep exploring. But yeah I'm getting more and more into Redshift and will share what I learn.
@@NewPlastic yeah, I totally agree with that, had been working with Octane since day one and I really miss it, besides the obvious there are so many little things that really give me a hard time working with redshift, don't know why so many studios use it. But especially because of its problems I would love to see how to get the best out of it! (mainly because I just have to use it..)
Amazing tutorial! A bit too fast for me but i managed to follow, how can I can randomly rotate the big scratches that you added last? Thanks
I do go fast! Can't randomly rotate just use the rotate transform to do that, some noises don't have that so you can just try another seed or change position
For some reason maxon noise in the new redshift began to be very small at skale 1 need to set 100 to see it as at setting 1, how to fix it?
I've been an octane user forever... but I've been considering switching. What do you think some of the pros and cons to both? You're the best man. Thanks for your work.
I might do a video about it when I wrap my head around it, but the biggest pro RS has is that it's owned by Maxon and has a huge potential in its growth. For me personally, crashing doesn't really happen with RS probably because of better integration with C4D. But another reason why Octane crashes more might be due to the way Octane uses the GPU, maybe pushing it way harder than RS. That results in Octane rendering faster, but crashing more often. If I had to choose one, I'll take rendering faster over crashing less.
So Octane renders faster, has a MUCH better sampling system (RS is just so confusing, and full of options you just don't need), and has a much much more robust node system.
I think RS has a quicker responding micro-displacement mechanism which is fun, Octane can take forever once you deal with heavy micro-displacements, but it just looks so goddamn good.
@@NewPlastic always coming in with thoughtful answers. Thanks man! I totally agree. VBD's in octane... crash juice. But it's speed when working in production is so hard to beat.
Do these not work in the latest version? after databasing them, they are not showing up. I'm new to the rendering side of all this, so it could (most likely) be me. but it seems the material libraries have changed their format.
Hmm, weird, I'll check it tomorrow. Thanks for letting me know
Very Great tutorial !! i have another question, how i can achieve an alloy, or managing a little bit the colour ?
Managing colors would be just carefully adjusting the IOR values for each channel.
For alloys, what I do is I look at what metals the alloy consists of, looking up their IOR values, and take creative control over how I mix them together.
@@NewPlastic thank you very much !
What a great in-depth tutorial. If I may ask a quick question - when I use UV Projection node, the Bump Map does not recognize it. So, while the isolated Color Layer shows all of my various noises, the actual surface of the material is smooth. Any ideas? Thank you!
Hmm. Are you sure you using a Bump node between the bump noise and the bump channel? Is it turned on high enough to show the bump?
@@NewPlastic Hey, thank you for the response! Yes, everything works fine if I remove the UV projection node, but as soon as I put that between the noise (or the ramp) and the color layer, the object loses its bump. It's odd, because if the color layer is isolated, you do see the way it is meant to look. Not sure if I'm missing a checkmark somewhere, or do I need the RS object tag?
Cool tutorial!! But for some reason maxon noise don´t seems to work with UV projection, anyone knows how can i solve it?
Thank you a lot for your tutorial is very useful ! i just have one question how did you find the wave lenght of redshift ? i mean it change for each scene or is fixed like the value that you said in this tutorial ?
The wavelength is fixed, what changes are the N and K numbers. The gold N and K numbers for 0.65 wavelength are different than the aluminum N and K numbers for 0.65 wavelength, and that difference is what dictates the different reflection "color".
@@NewPlasticunderstood thank you !
Yo, Finally Redshift! Always great, would you shade a metahuman?
I tried to render a Metahuman in redshift and I couldn't get a realistic result.
Any video is always appreciated!
You know it's something I've been wanting to do for a while. Last time I checked (around last year) exporting the metahuman outside of Unreal wasn't that easy to do, but maybe that changed it
@@NewPlastic in fact, I exported the metahuman to maya, with the rig and the various controls and after that I exported the obj to cinema, I succeeded, try this method, also if you want to animate it you can export an alembic
@@NewPlastic but to find a tutorial with really realistic skin shader is very rare, every day i try to find something new
wow, what a master
Thanks boss!
I learned your operation, and there was no problem with the rough connection, but there was a problem when connecting to the bump, which made me very confused.
I use the latest version of the software.
Where do you go those RGB wavelength numbers from?
So IOR gives you infomation about the amount of reflection. But what about the fresnel? How does Redshift know about the fresnel of a material? Is it only defined by metalness? That would mean that every metal has the same fresnel?
The last fortress has fallen 😭😭😭. Redshift from scratch...
Nothing like scratches from scratch!
@@NewPlastic axaxaxaaxa
Are you completely abandoning octane? :(
Nah not at all. I love Octane, and it's still king.
Man, please don't move over to redshift 🙏🏻 everyone seems to be switching to RS, aside from speed I can't understand why...
Haha trust, I'm not moving. I'm just expanding. Redshift isnt even as fast as Octane.
@@NewPlastic thanks man. I watch your Octane vids on my commute into work. By far the most comprehensive for advanced topics.
great tutorial but you go WAY TOOOOO FAST.
Yup I know, I do go fast, but honestly that's the only way I can do it. And that's how I watch tutorials too! At fast speeds, always moving forward. Maybe it's my ADHD
No more Octane please!
Haha why? Octane is incredible. Better than Redshift honestly. But it's good to explore and expand
man we need more redshift
I got you bud
