Jewelry Design / Organic - Rhino - Zbrush - Keyshot

1. Intro - Organic jewelry modeling - Rhino - Zbrush - Keyshot: Hello everybody and welcome to my new jewelry design class. This class will be focused on the students who'd like to learn how to combine Rhino with the ZBrush and to use key shot for the end result for the renderings. So in this specific class, I wouldn't be talking too much details about how to use specific tools in Rhino. I'll be just focusing on simple 3D modelling. And then I'll be trying to explain you how to import this model when to ZBrush, how we can do changes to this models to achieve, to define a look that we want. And the final stage is how to import this 3D model into key shot so we can get our renderings. This class should be kind of an overview of the techniques from 3D modelling, the implementation to D3, the detailing and ZBrush and 3D rendering and Kishore. So you can have an overview of how this workflow is going. I'm going to try to make it as simple as possible so every one of you can follow. And there'll be other more classes to talk a bit more about jewelry design and other specific things. But for now we're just going to focus on this specific workflow. Let me see and hear what you think a common sections so I can maybe implement some other design lessons and talk about other details in my next classes which I prepared to launch this year. So thank you for following and let's move on to show you how to do this. 2. Rhino organic modeling: So let's start with our 3D model. In order to achieve this result, we're going to start first by, by drawing the rail of our ring. We're gonna do that by selecting the circle. So we have a circle with the center and radius. Once we select the circle, it says the center of a circle. So we want to define where at the center of the circle, I believe so far, if you use the Rhine already, you should know. Let me start from the center and that means we type 0 and press Enter. Once we do that, we see that we start drawing a circle from the center. And for the dimension, we can use 60 millimeters diameter, does the diameter that we usually use for size six, size sudden ring. And that will be okay for our project right now we just use producers type 16 millimeters if you specifically want to do according to some other dimension, that is also up to you and you just make sure that you know which diameter you using for the specific ring size that you measure it before. So I'm going to use the diameter is 16 and I'm going to press Enter. This is what I got right now. So in order to achieve what I wanted to do now, I need to first measure like, how big is this circle? What is the distance of this circle line? So I'm going to type length n is going to tell me that the length is 15.265 millimeters. What I can do now is I can take this distance and I can copy it. Once I copy it, I can just draw the line next to this circle like this. And I'm going to, for the purpose of this project, I'm going to turn on the grid snap because they need to use later some symmetry. And this is going to enable me that the good symmetry. So once I click End to draw a line next to it, is going to ask me, ask me where is the next point of a polyline? Because I already copied this length of a circle that we had. I just going to click paste. And now I have, as you can see, the line which is the length of this circle. And I'm going to click, and after that I'm going to press Enter. So now that I have this line, let me first to realign it somewhere closer to the center. So now that I have this line, I can play with the certain shapes that are going to draw along this line. And then I'm going to use that shape to flow it along this circle. We're going to have some really interesting results. I'm going to first just draw some simple shapes so you can see what I have in mind. So let's say if I do something like this, and then maybe add another line like that. This is completely unrelated for now, don't worry about my design. We're just going to use this as an example. If I have something like this, I'm going to use the command that is called flow along. So just use the current flow. He's going to ask me for the base curve, select near one end. So because this is my base curve, the length of this circle, this horizontal line over here. So I'm going to click on it. And then he's going to ask me to target curve, and this is my target curve. So once I click, you're going to see that something really interesting happened. And that is that all the lines that I drew over here, we're going to get here. So what I can do now is I can use the pipe tool like a Round Cap Type Tool. And I can click one-by-one and define the radius to be 0.6. And I can just repeat it again. And I can repeat that again. And we're going to get the result that something like this. Let's check that in our shaded view. So as you can see, for this specific purpose, I didn't even design much, right? As you saw, I just randomly draw a line. But as we transform it into a tree deem we found something really interesting. And that is that once we flow those lines along the circle and transform into a treaty, we can actually get some interesting shapes. So this tool and process that I teach you is something that I want to teach you how to utilize this tool to steal the sketching something in jewelry design and design general, especially in 3D, is really important. How to get the quick sketch of what we wanna do and then think how to change. So for example, once I know what I can achieve with this tool and I can see this shape for me is now very easy to just go back here, turn on the curve, edit points, and just move them a little bit here and there and see the end results, how it can look like later. But for now, let's just take what we have here and see if we can turn this into an interesting piece of ring. So this process I'm going to save, I'm going to save this model as STL file, and I'm going to import into ZBrush and then show you what we can do in ZBrush to it and how it can make it into something and actually try, I'm going to try to get her with you to turn this into interesting piece of ring. Let's help. Let's hope to see what is going to be the end result. So first what I'm gonna do, I'm gonna select this without this line here. I'm going to select this object and go to File export selected. This is my organic modeling rendering. Here. We're going to save this as the STL file. I'm going to call it organic ring model. Okay. I'm going to press Enter for that and enter for this. So now that we have this, the first part of modelling should be done. And we can proceed to ZBrush part. What I want you to know is that every time I draw a line, my line would end at the endpoint of this baseline. As you can see here. That way when this flows along the curve, all these lines will connect at certain point. So here you can see this very weird point here where all the lines connected, that is where all my lines that connect. If you want to make an open ring, you can do similar thing like that. Just the lines open. And then you're going to have something that's more open like a branch drink that doesn't close and one edge. Just bear in mind that if you want to ring to be closed, all your lines needs to finish in one specific end. That is for our modelling part. And now we're gonna go to ZBrush and do some fun things to this model. 3. Zbrush modeling: Okay, So thank you for following so far. I hope you'll open your ZBrush for now. In this specific tutorial, just keep in mind, I'm not gonna talk too much about treating modelling tools in Ryan. I'm going to cover that in audit tutorials. This tutorial specifically for you to find a quick way to sketch in Rhino and you can use the same model that I did. So you can use the same flow command to flow certain object and to make a ring. But also you can use something that you did yourself and then just implement the same strategy and techniques that we learned throughout this tutorial. It's all up to you. So just bear in mind that this tutorial was not specifically for 3D modeling in Rhino. I'm going to talk more about ZBrush and key shut later. So let's now turn off the light box for a zebra. Or sometimes when you open a ZBrush and beginning had the light box. And once we turn it off, we have our document open and clear to see what we're working with. If you need a light box, you can just click back and open it. There you can see the different models that you can use from the lightbox project. Anyway, let's go to our import 3D mesh. So we click Import and we're going to find our model, organic treaty modelling, organic rink model. And we click Okay. So it says draw. So if I click and draw, I should have my model on my stage like that. And then I'm going to click Edit. This is very important because if I don't click Edit and just keep on drawing the model and it's going to look like a mistake because we can have many different 3D models here. So we just click on Edit. Now when I click Edit, if I click on the side of a ring, I can rotate it. If I hold Alt and click, I can get around. Maybe this can be a little bit different for Mac users, but probably it's just pressing Command or similar things like this. Let's go and see in a sub tool, we can see our model and let's see what we can do to our model. First, let's analyze the poly mesh. So I'm going to click, right-click and the drop poly frame. What that's going to do, we're going to see the frames of how hiring and training model is subdivided, which is also very important. Okay? We can turn that off. It looks like pretty decent. We're going to change the structure of our 3D model and their subdivision later. First what I want to try to do is I'm gonna go and use the Move Topology tool. Let's make that a little bit bigger just to see what the mall typology does. So once I click with a specific part of the topology, I can move it. Because in Rhino, I created all these lines, a different pipes. Let's call them like that. Therefore, if I click on one and move it, I'll be able to reshape just that specific pipe. Let's first play around with that. And that's why I told you that for this tutorial is specific 3D modelling in Rhino. I don't want to focus on that because I want to teach you the power of ZBrush and rhino combined, which is something that I found very interesting. And I think once you master that, you can really create amazing, amazing models and designs. I'm going to click on a different part of this 3D mesh. And I'm just going to play around with it a little bit and see what I can achieve. I'm going to try not to mess it up vertically, which means not to go in this direction. I just want to go horizontally. Engine, click around and see what I can do to the mesh itself to make it more, let's say organic or just more interesting. In general, I'm going to use more Topology tool. I'm going to circle around this mesh and see what happens. There are some straight lines. I'll try to break them apart. Just two. Let's check if everything is okay vertically. Mess it up too much because we need to maintain the circle shape of our rink. Keep on doing what we've been doing. I'm gonna make this smaller. Maybe not that small. Like this, that's fine. Just try to make this a little bit more interesting than just very straight lines that we get from Rhino. Because Rhino is a really good software if you want to do something very precise, but if you want to do something more organic, more like you designed with your hand, Rhino is not really good software for that. So let's see what we got here. Okay? Something like this. I think it's okay. Because now what I'm gonna do is I'm going to use the Snake tool. But before I use the Snake tool, I'm going to go to my geometry. I'm going to go to DynaMesh, and I just got to DynaMesh all of this. So what that's gonna do is gonna connect it all into one object. And you can see now it looks like it's welded together and not like it's all made from a one piece of clay. If I hold shift like Smooth Tool, click around, we can get results like this. So this is why I told you that even though in my Rhino file, which I'm going to show you pretty quick here. Even in my Rhino file, we got this mess here. And the edge that we created, ZBrush is placed where we can turn that mess into something like this. And now imagine creating the same shape like this in Rhino. That would be really long and complicated task. So now we're gonna play with the power of ZBrush to connecting these lines together. I'm just clicking shift, so you're now is the smooth tool. And with the smooth tool, I'm able to smooth out all these edges that were a little bit weird after we use the DynaMesh tool. If you don't know, the DynaMesh tool is right over here and you know, it's active, but just because it turns orange, He's going to just connect all your shapes into one shape. You can play with the resolution. So the higher the resolution of your DynaMesh is, the higher resolution you're gonna get different model. But we don't need to big resolution because for now we have like 29 thousand polygons. For now. That is okay. It's always better to start with a lower res, model, play with it as much as you can and then add resolution to it through subdivision. So this is one of the way you can do it. Like you can easily go to geometry or you can go to geometry and just click Divide. And once you get divide, you can see, you can see just a second. So for example, this is our model that has 29 thousand polygons. But if I go to geometry and I click Divide, we can have, we can see that we now have a 114 thousand polygons. So almost like six times, five times that. So first we're going to play with the low poly and tried to get the best result from debt. And after we're going to see what we're going to do, what I'm gonna do now is I'm going to use the clay buildup tool. And I'm going to just draw some lines to try to add some, some texture, some shape, some dynamic to the my treaty model. Bear in mind that for this, I am not using any drawing tablet like a synthetic or are bent back and bamboo or anything. I'm just playing with the mouse because I assumed it. A few who want to play with the ZBrush. It's really good to have actually any drawing tablet you can get. But some of you maybe not going to have something like that. And the reason why I'm working on it with a mouse is to show you that you can achieve some really good handmade results, even by just using a mouse and none of those specific equipments. So I'm just working now with the mouse and you can replicate the same what I'm doing. If you have a drawing tablet, you can use the drawing tablet and just do similar to what I'm doing. I'm just going to use the clay buildup tool. I'm going to show you again where it is. You can go here. And here it is. Clay buildup tool. That tool is going to let you achieved a result that like a solid line of like a cube of clay as being laid upon your model. So that's what we're gonna do and I'm gonna do this a little bit quick. So not spend too much time on what I'm building. So everybody can easily follow. As you can see, I'm trying to maintain always my vertical dimension of my models. So never to mess my model and this direction. But actually to mess it only like horizontally. If we can say that. This should be fairly finished. Just a couple more lines here and there. I'm doing this to achieve some soil profile, let's say row or C. I messed it up a little bit here. So I'm just gonna go back and smooth it out with the Shift, holding shift on my keyboard and clicking. By the way, here we have something called Z intensity. If you think you're, when you click and draw it's too intense. You can make the Z intensity light less, for example, five. And you can see now the intensity of which clay is added to my model with this specific tool is much less. So. I like around 1415. For me that is okay. I'm just going to quickly block this out. Smooth it out inside just to make it comfortable. Don't forget, we're just doing a quick sketch. This doesn't need to be a final model. What we're learning here in these tutorials, how to do a quick sketching. Sketching is as important as the final 3D model. If you can achieve a quick way to sketch your 3D models and 3D jewelry, then you will be very much more productive than if you spent one day 3D modelling something that a T and you figure out it's not something that you really want. Okay? Now, it'll get more and more topology here because I see that this part is to ten and we might need to make it a little bit thicker. Another way to find some places that you may be dropped. The process of smoking, which because that's usually what happens. So trots smoothing, they happened to be too thin. You can go to your brush tools and use magnified. Once you have magnifier tool, make it a little bit bigger. Just click on that part of the model and you can see we can instantaneously make it, make it bigger. This very nice and fun way to play with it. What I wanna do now is I'm going to go to my geometry. I'm going to Chris divide. So that way we can get a lot more polylines to work with and polygons to work with. So we can see here it's fairly detailed model. Another thing that I can do is I can the scene like how I can do the smoothing by holding Shift, I can actually increase the contrast. So if I hold Shift and Alt, that's going to increase the contrast of my model. So if I have some shapes that I want to increase, I'm just going to hold Shift and Alt on Windows. And I'm gonna get some really interesting shapes. You can check it out. So we get some really cool textures. Almost like really made by hand and clay. Now let's go back to move topology. And this time I'm going to use much smaller brushes q2. And we can play around some edges to try to make them more organic. This is why we always first work with the bigger tools and bigger scale. And then we use smaller tools and smaller scale to add detail. So never add detail before you're satisfied with the overall shape. Always first work, the forum, and then on the subject of your model, same like in any class of sculpting or drawing, like this specific dynamic of a whole object that you're drawing or painting is much more important than the detail itself. If everything is okay and it's dynamic and it's size, then once you add detail is just going to look much better. So as you can see, you can use the same topology tool to play around and you can achieve some really cool and realistic effect, almost like a tree branching. And very natural. Like this. Okay, let's take a look at our model. Cool. So that's something that I'm more or less happy with. Now that you followed along this, we're going to go to the third part of this tutorial, which is about key shot rendering. So we can work a little bit in key shot to try to render this into our final piece of jewelry. And just to show you how you can easily use key shot to get your 3D models nicely rendered without too much effort and time. So what you're gonna do before we go to another part of the tutorial as we press export and save this as OBJ file and ready for renter. Okay, thank you for following this part was a little bit long, 15 minutes, but I hope you'll learn something cool and new about ZBrush. If you have any questions, please leave them in the comment section below, or something that you wish me to cover in the next videos. So yeah, keep me informed and I'll try to make a content that suits you the best as a student and follower of this class. 4. Keyshot - rendering: Okay, Hello everybody. And now we're in our third part of our tutorial. And this is the first time I talked about the key shot. I'll try to make it as simple as possible so you can follow as well as the cover some basic things that you need to know about Kishore. So this specific tutorial won't be teaching you details about how to work in Q Sharp. What I'm teaching you is how to achieve a quick result with what you already have. And it is a 3D model of a ring or a jewelry that you created and produced. So other tutorials we'll be focusing on how to go in details, how to use Kishore. What I want you to know about in the beginning is first what you wanna do is you're going to drag and drop your modeling turkey shot. So when you start to go Kishore, you go File new and you have a new surface and new document to work with. Once we have that, we're going to find our 3D model and drag and drop it straight into the key shot. He's going to ask you to import. You don't need to worry about anything. If you create an OBJ file from either Rhino or ZBrush, the workflow will be the same. So we're going to click Import. And now we have our ring inside of a kitchen. For now there are no materials, there's no specific lighting, they just general lightning that comes with the first file of acacia. So we're going to start building something around. But first I want to tell you how to orient yourself around key shot. So you have three buttons over here. One is tumbled, one is pen, and one is Dolly. And every, each one of those does the specific camera movement. So unlike a rhino and unlike ZBrush, where you would just click around your model and either hold Alt and just click and drag and you can rotate in key shot. You need to get used to these three tools. So sometimes if you don't see a ring properly, maybe you're gonna go to tumble, click, and you're going to move your camera around your ring, or you're going to click pen. I'm going to move left and right, or you're going to click dolly, zoom in and zoom out. So these are bursting to need to know how to orient a cation. Okay? Whatever you click on your model. For example, I double-click my model or just click it once. Here you have seen material camera, environment lightening and image. First, we're going to go to scene. And this is what we're working with. This is our organic ring model over here in a group under name. You can change it to, for example, ring model. And this is how it's going to be called right now. So it's easy to know that this is under your model set. These are cameras sets, environments, but the camera and environments now you don't need to worry because we're not using this for now. What we're using for now is just like a model set. So focus on that. Okay. Let's add a background plate. Once we add a background plate, we can do a little bit of orientation, move our rink on the background plate, position it. And after that, we're going to add some materials to it so we can play with materials and light. So we got to edit, add geometry. And there's something called plane. So once we add plane, something like this, you don't see it because it's really small or our rink is really big. So we're going to click on plate and move selection. If you don't have something like that, maybe let's say you see something like this and you don't know what to do in this moment you go to scene. You'll click on plane, or click on plane like this with your mouse. Once you click, you got right-click. Once you see that your plane is selected, you've got right-click move selection. Once you click Move Selection, you have three options here that you can turn on and off. You see once I click, they changed the color. So what I want to do is I want to scale it, okay? You can choose it by typing in the numbers. There's other options inside, but that's not something that I need. What I need is really simple just to click on this yellow box in the middle and drag it. So when I'm teaching is really simple method without needing to know too much about software, how to get the specific result which we need. As a jewelry designers, we don't need to go too much in-depth of how to use some specific things in specific software. If we just need to render, for example, a piece of jewelry, we don't need to know. I like everything about that specific software. So once that I clicked in the yellow square in the middle, I dragged and dropped and as you can see, I resized it to specific size. That's okay. That covers the whole surface of my camera. So I just said it. I just see my whole camera view. I see that background plate. I click. Okay. And another thing I want to do is I'm gonna go to my ring model. So I'm selecting my ring model. I go select, Right-click Move Selection. We have more selection and go to translate. I'm going to turn off the scale because I don't want to scale anything right now. I'm going to move it like this. Maybe I can now rotate it a little bit. Here. I'm going to type. Just a second. I'm going to click on rotate. I'm going to type 90 degrees. This is okay. And as you see, for example, now when I rotate it, it's out of my camera, I don't see it. You need to go to pen. You click pen and new track down. So this is why this software is a little bit different than the rhino and ZBrush. Camera movement are done with this tree. Specific options and you need to learn to use them. Once we have that with our ring model selected, tried to right-click it again, more selection and click snap to ground. What that does. If you have like a key shot ten, you'll be able to snap your model to the ground plane, which is the plane that we created right over here. And by doing that, you don't need to do it manually. I think in some earlier versions of key shot, you don't have this option and luxury to do that. But if you have Kishore ten, you can just click snap. The ground is going to snip it immediately if you don't have this option, well, what you need to do is you click this arrow that points to the ground and you're probably going to do some movement by hand. Here we have three options like performance mode. If your computer is too slow, you can turn on performance mode and everything is going to be much quicker. But the result that you see in your screen, it's not going to be great. And you have a GPU, you can use your GPU if some of you have a really good graphic cards to do some rendering for your calculations. So you get a really nice view. And very, fairly quick, right, as you as a live view. Once we have that, let's start to play with some materials. So first thing, that one I'm going to do is I'm gonna go ahead and click on the materials on my left, It's under library materials. So once I have that, if you don't have this, by the way, if you don't have seen project and library materials, they should be here under this under this tab. So you have library projects, animation, key, SWOT, XR, and render. For now, we're just focused on library and project these toys which I use the most. So under library, you go here, you have different things, you click materials and other materials. You have many different materials you can choose. Some are concrete, liquid water and stuff like that. But what I found really interesting and maybe you'll find out the scene is we feel something like ionized aluminium. We can get some pretty cool results. So let's check it out. So I drag and drop this iron and aluminum. And this is now my background. And as you can see, if I move it depending on where the light is on that scene, I can get some really good results. One thing, if I click Control and then click on my background and drag left and right, what's going to happen is my lights scene is going to rotate. This is rotating. All my life seen an environment. So I can just move it like this and get some really cool effect and shadows without too much work. So this is what I wanted to teach you how to utilize the t-shirt to get good results without too much effort. You don't need to be professional in 3D modeling or in using key shot or using 3D software to get the good results for the work you did as a trading modular or as a jewelry designer. You can just use some simple tools that are available for you and just get the good results good enough for you and your clients and your portfolio. Once we have that, we're going to go back to materials, metal, precious metal. And here you have different materials you can use. I'm going to use a silver rough for this example. You have silver texture that you've have different ones you can choose and pick. So you can just play around with it. Or platinum rough, click and drag and drop onto your ring model. You can go to the right or you can directly to your model over here and click. Once you do that, Just release, and there we go. Let's zoom in a little bit and see how that, how good is the result that we have really nice texture. Now as you can see, we have a lot of these triangles. This is happening because if we go back to our ZBrush, you can see that in ZBrush. In ZBrush, the amount of triangles that we're having, we got two sub tool and just hover every model is 114 thousand. So if we, for example, go here under Geometry and just divide more and more, then we're going to have a much bigger tree model. This one specifically, we have almost around 2 million polygons. That's gonna be much harder on your graphic card, but the result will be much better. And you won't be having those triangles. Because if you go now in Pali and you see dislike a lot of surface to work with. If you need something that's really high defined and you need to do a very close-up shot. I suggest you to just go to geometry and divide increase. The amount of polygons that you're working with. But if that's not something that you need, then even low poly model is okay. Because for example, for this specific model, I'm going to, I'm going to make a picture from here. So that's gonna be just about right. Now. Last thing that I want to do, maybe just a little bit of lightning, for example, like this. Last thing that I want to do is gonna go to Image. And here I can play a little bit with photographic exposure, white balance, contrast, curve, things like this, saturation. If you're familiar with how to use any Photoshop tool for raw camera or any raw camera editing tool. This is gonna be really interesting for you. So for example, I can change a little bit of exposure. Maybe white balance to the greenish side. Add a little bit to the contrast. Now, what I want to, I need some vignetting because it always gives a nice feeling. Maybe saturation, maybe it just slightly less saturated. I think that's what makes it good. And vibrance is also on a nice side. Curve. If you know how to play with the curve, it's also nice. Increase the shadows, lights, whites and things like that. Sorry for that. Okay, so now that we have this, we can go to our Render tab. Under render, we can choose where we're going to render the folder. I have this specific folder that I called organic modeling and rendering. So I'm going to select this folder. I'm going to call this render one. Now that we have that you want, you can choose the preset that you can use for my preset is 1920 pixels, wind, 1080 pixels. And I just going to click Render button. Once we click that, you're going to wait a little bit until it's rendered. And then he says a 100%. And here it is. If you go to a folder, you should be able to have your piece of jewelry rendered and ready for you and your portfolio. Last thing that you can do is everybody who does a little bit of rendering of still images can use later some Photoshop software or other software to just add a little bit maybe of details on certain parts and just changed a little bit of contrast or anything like that. Any photo editing tool, even some free photo editing tool that you can use on your phone can get some pretty cool results. So that's it for this lesson. I tried to cover a little bit of Rhino, maybe a little bit of ZBrush, and a little bit of key shot just to show you quick workflow that you can implement in your design strategy. And the workflow that can give you really good results and that you can use it if you want to do some quick sketching. So not necessarily to doing the final models, but the quick sketching to you so you can see the quick results of what you're doing.
