V-Ray | How to do BRUSHED METAL Materials | Anisotropy

In this tutorial you will learn how to build the most commonly used Brushed Metal or Anisotropic Shaders. We will first use Bump or Normal Maps to build basic Surface Imperfections. We will soon learn that V-Ray offers a much more optimized workflow which is using the Anisotropic Parameters of the BRDF. This way we will get a much nicer and more optimized result. Finally we will also develop a hybrid approach which will combine the use of Anisotropic Shaders with Bump or Normal Maps to generate the most realistic result.
I am using 3ds Max and V-Ray 5 in this demo but you can also use the same techniques for older versions such as V-Ray NEXT and V-Ray 3.
A similar workflow can also be used in other software such as Cinema4d, Maya, Blender and different kind of render engine such as Corona, Octane, Redshift, Arnold, Cycles, CyclesX, Eevee and countless others.

Thanks mate! Finally the best tutorial about brushed metal 👌🏻😘😘😘

[@ss54dk]

you are the most best tutorial of vray in youtube world

[@3DRnD]

As always great tutorials.. 👍

[@sagarpanchal5011]

Thank You 🌹❤ So much Jonas

[@tobiasnoll5359]

Finally a new video 👏

[@jimmwagner]

Using this method on a project as we speak. Thanks Jonas!

[@JonasNoell]

Cool 😀

[@SRaheelGillani]

very nice

[@abdullahubeyd3060]

thanks

[@chrisheath786]

Thanks Jonas. I have a couple of ideas for shaders. Your take on a complex velvet shader and the dreaded towel shader! Never seemed to find a towel shader that was totally realistic whether using displacement or scattering. Always end up comping a real photo in. Wonder if you can crack it :)

[@JonasNoell]

Oh alright, that's interesting. Thanks for the ideas! 😀Will put it on my list!

[@addamski]

Nice, would also like videos more frequently if you have the time. How about animated environmental fog 🤞🏻😃

[@JonasNoell]

Yeah will try to be more regular, though sometimes time is limited. If you flood me with good ideas it's also easier to find a good toppic :) Idea about Fog is great, will put it on my list!

[@gumby3057]

Nice, thanks. Environment, light placement and camera angle plays a part on reflections right?

[@JonasNoell]

Yeah for sure, as usual with metallic shaders the environment is the most important factor.

[@pixelquarry]

Long time no see ;) Very helpfull tutorial yet again! So you do need proper UVs for both approaches, either for mapping an actual bump texture or to control the direction of the anisotropic effect, right?

[@JonasNoell]

Hi, when using Anisotropy in the local axis mode you don't need any UV's, unless you wanna blend in some scratches with the bump :)

[@pixelquarry]

@@JonasNoell Right, but as your example shows just using the local axis might result in weird effects. If your cones were merged into one mesh without UVs, local axis orientation wouldn't work. That's how I understand it.

[@JonasNoell]

Yes, local axis sometimes works if you for example just have one cylinder or some other simple object. But as soon as you have one object where you want to have multiple anisotropic effects with different directions you would need to have some kind of UVs to control the direction.

[@gekfurian]

Great tutorial. The problem I'm having is animation. If I rotate the cylinder on its local z, like a lathe or similar, the hourglass reflections in the base tend to rotate with it or in some other weird way. Like it's depending on local uvs or maybe it's a map gamma issue. I feel like I'm losing my mind.

[@JonasNoell]

Yeah that is indeed an issue. Actually I haven’t found a solution for this issue yet as the UVs rotate together with the object. You could open a thread on the Chaos forums, would also really like to know how or if it’s possible

[@abdelrhman1251]

Do you recommend the use of color2bump map? because Vray docs says VRayColor2Bump is slower, & it is better to Directly plug the bump map to the mtl

[@JonasNoell]

Hi, I would at least recommend to try out the Color2Bump conversion if the bump is a very important part of your shader. Often times I ended up getting better results for some reason even though I just plugged in a simple Bitmap. As with the example in this video here the result looked also different and better when using Color2Bump. So in my opinion just test it out if there is a visual difference. I can't imagine the performance to be drastically worse to be honest, at least I din't really encounter anything noticable as of yet. But definitely always use it though when you blend procedurals or multiple textures together or have in general a more complex setup for your bumpmaps.

[@abdelrhman1251]

thank you😀

[@punithaiu]

@@JonasNoell i always thought color2Bump is only used to convert a color map into a bump map in case a dedicated B/W bump isnt available. i assumed its just a faster way to create bump map instead of going out to photoshop and creating bump map from the diffuse map

[@scpk2246]

Hi Jonas, can you please make a GPU RENDER SETTINGS video? so we can a starting point thanks

[@JonasNoell]

Seems like a good idea, will put it on my list!

[@hengchaozhang5755]

缝隙之间的焊缝怎么制作的啊？ 有视频介绍吗？

[@JonasNoell]

VRayEdges and some masking

[@bharatprajapati5260]

Sir How did you get these both maps????

[@JonasNoell]

Which ones? All the maps are on my Patreon

[@iamski]

Jonas, what's the hardware (cpu, mobo, ram, gpu, etc) you're using for these tutorials? And you're using cpu, not gpu rendering correct? And which version of V-Ray? Also, in terms of ideas for a tutorial, there quite literally isn't a single good tutorial out there for making crystals like quartz or amethysts. Only one I've seen which has come close to the shader I'm looking for is a Houdini one like this: kzbin.info/www/bejne/pqKVk4yQfNqlsMU You'd get mad views if you could do one for the rest of us. Me and hundreds of others would be eternally grateful if you did. Danke!

[@JonasNoell]

Most videos are with Dual Xeon 16 Core, 64gb Ram, Quadro P1000. I don't use GPU rendering, don't really have good hardware for that. The idea about the christal is cool, will definitely check that out! Thx!

[@iamski]

@@JonasNoell Thanks dude. By the way, which model # xeon you using? Since there's various ones.

[@JonasNoell]

E5-2698 v3, but why does it matter? You can render with any CPU :P

[@iamski]

@@JonasNoell I'm kinda in a tough decision whether I want to stick to GPU rendering (own a RTX 3090) vs going CPU for my future projects. I've noticed in some benchmarks and real world tests that GPU outperforms even Threadrippers in certain cases, so looking at the preview renders is interesting to compare. That's basically what I'm getting at. Thanks by the way for the follow-up.

[@JonasNoell]

​@@iamski Ok, as said most videos were with Xeon, but I recently upgraded to Threadripper 3990X, so this Brushed Metal is the first video on the Threadripper. Would be interesting to see a comparison btw. RTX 3090 and 3990X. In my tests it renders around 3-4x as fast as my 2 x 2698v3, is quite silent and probably uses a fraction of the electricity than the 2 Xeons. Very happy with that CPU, but in terms of Performance vs. Money there are probably more attractive CPUs on the market. For GPU rendering I personally didn't really do it a lot so far, because my CPUs always outperformed my GPU. I imagine with a 3090 it's probably another story. So unless you own a highend CPU, or require some V-Ray CPU rendering features, I would imagine for you GPU rendering would be the way to go.

Hi Jonas I want to join your Patreon. But i don't have debit card - But i can pay you with Google pay. If it's possible please reply!

[@JonasNoell]

Hi, since the whole content is up on Patreon you would need to use a way that is compatible with the Patreon Platform, sorry :( I think they offer PayPal though...
