    Help, how to get such a surface of stainless steel?

    Hi,
    I've been struggling all day since yesterday... Please help. How to get such a surface of steel as in the attached photos? I have Cinema 4D R20 and can only use Classic V-Ray. I even started to create a pattern made of many offset circles in Adobe Illustrator for bump and specular maps, but the result is not satisfactory. I can't send a 3D scene because it's a confidential item.

    I am asking for help and thank you.

    Hello krzysztof_malec

    The first option is using Chaos Cosmos or V-Ray Scans and choosing from one of the numerous steel and metal materials available.

    The second option is creating texture maps (bump and specular as mentioned) in a 3rd Party Software and using them via V-Ray Material in Cinema 4D.

      Thank you for your answer. Here, an additional difficulty is the anisotropy of the surface, which is very irregular. I want to achieve anisotropy using a specular map, but I'm not very good at it, so I use a blend material with a separate anisotropic material and mix it with the material I make circles with.

        What you could try is use the Reflection > Anisotropy feature of the V-Ray Material.

        Regarding the blending, it is possible to avoid it by using a Bump map so some parts of the surface would reflect the light differently.

          you need anisotropic textures for such things, bets also soem bump/normapmaps that fit you find some in our vray metal materials library (but not same) at 3dtools.info, but yu can also make that yourself in psd

            Hi Krzysztof, check these great shaders from sirio76
            3DRnB Metal Shaders for V-ray 5 Cinema4D
            https://3drnb.gumroad.com
            Click here for BLACK FRIDAY 50% OFFV-ray 5 Metal Shaders for C4DWe are proud to release our first product for V-Ray 5 for C4D. Every material we made has been carefully crafted, starting with a proper data acquisition from real world samples to see how materials behave in real life and in different conditions, and then trying to reproduce all the shading properties with great accuracy. The result is a collection of over 300 high end metal shaders accurately tested to be production proven, featuring high resolution textures (diffuse, specular, bump, normal, displacement, alpha map, typical resolution up to 8K), chromatic variations of the same shader to quickly choose the one you need without tuning the color, all of that in a practical .lib4d file for the Content Browser in order to find easily what you are looking for. Many shaders have been build in a modular way so that you can easily mix and match some characteristic to create even more great looking shaders. Content BrowserAll our shaders come with a .lib4d file for the native Cinema4D Content Browser. The collection is organized in folders and subfolders. Inside the subfolders you will find each shader with his chromatic variations.By clicking over the icon you will get the preview of the shader, you can scale the preview windows up to 1024 pixel in order to have a better overview.The previews and the lighting setup have been carefully tailored to give the best possible feedback over the appearance of the metal, when needed you will find specific setup for displacement and anisotropy. Content Browser Preview ImageEvery material in the library comes with a High resolution preview, and a lot of information like:-Name of the Metal-Color variation of the Metal-Reference scale in cm and inchesin order to have a quick feedback of the size of the real metal sample.-Tiling information for scaling the shaders properly when using cubic projection-Examples of typical uses of the metal-Tips to get the most out of our shaders. This will vary from time to time depending on the shader setup Support for Both CPU and GPUV-Ray is famous for the robust CPU based engine, but our shader will work on GPU too.You can use our bundle on Intel and AMD CPU, and by switching to the GPU engine you will be able to use both CUDA and RTX kernel available on Nvidia graphic cards, if that isn’t enough you can even use Hybrid render to use CPU and GPU at the same time, we have tested this and it is FAST, like VERY FAST!This versatility makes V-ray one of the most complete solutions available on the market. Sample Shaders Test our Free sample shaders. You will find 6 Shaders with 48 variations always with a .lib4d file in order to enjoy the Content Browser. You are aloud to use them for both personal and commercial projects. Make sure to tag us on social media @3drenderandbeyond (twitter @3DRnB) if you enjoy our product.DOWNLOAD DEMO SHADERSPDF Catalog Here is the PDF catalog to see what’s inside our bundle, you can choose to view it online or download either a high quality or a low quality catalog.ONLINE PDF (Interactive flipbook)Download: HIGH RES. PDF or LOW RES. PDF System RequirementsCPU - INTEL or AMD, (M1 Coming soon)RAM - 16GB (32GB or more recommended for displacement) The Product have been tested on both MacOS and Windows Systems using V-ray 5 for Cinema4D.We have tested the product from R21 and above but it should work also on R20.

              Hi Stefan,
              A very nice collection of materials. Thank you for sending the link. If you help me achieve a similar effect, I will buy your collection. Unfortunately, I don't have time to experiment anymore. Each collection is missing the surface effect I am trying to achieve. All materials are repeatable. Here, the difficulty lies in the lack of regularity of the pattern and showing the exact surface characteristic of machining - milling. These are not microscopic flaws in the metal, this is the effect of the cutter's work. There are no ready-made libraries with materials available here.​

                Hi Filip,
                An equally beautiful collection of materials! I already bought it before. I'm trying to mix it up right now, but I'm not very good at it. ​

                  "If you help me achieve a similar effect, I will buy your collection."

                  well i can help you, there is one irregular brushed material already a in it and i can edit it to your needs for example or create a new one. bets email me to: shop@3dtools.info

                    My thinking would be, to get 100% accuracy, you'd need to model this and make sure all the UV's are correct direction and then in the ano filtering in the material set it to UV coordinates. This would give you 100% accurate result. You could use a texture map to drive the model with a displacer and then UV....the challenge there will be to UV it easily and accurately. VS modeling it you'd be able to select the edges and break it apart with your UV mapping more easily. We have some clients that are SUPER picky on this stuff so we've dealt with a ton of this lol

                      I have a 3D scanner, so if I had the original item I could try to scan the model. Unfortunately, such surfaces subjected to machining (milling) have a random texture, each time a different one. It is not a repeatable pattern. My client is not a purist (fortunately), but it would be nice to show him that you can get close to such a surface texture.
