The Usage of Maya 2018 Attribute Spread Sheet

If you're a 3D learner and love the Superman movie, it's time to make a 3D Superman just for you. Now, follow the industry's best cloud rendering service provider and render farm, Fox Renderfarm, to see how CG artist H cheng made his Superman.Final results of 3D Henry Cavill Superman:!3D Henry Cavill Superman!3D Henry Cavill Superman!3D Henry Cavill SupermanThe tools used in making 3D Henry Cavill superman are as follows:High-poly: ZBrush, Marvelous DesignerTopology: Wrap4D, MayaMapping: Mari, Substance PainterHair: XGenRendering: Arnold/UE Collection of MaterialsBefore we start, we need to decide the theme and collect the required reference material. I chose Henry Cavill as Superman model for this project. Then we can try to collect as many photos of his stylized look shown in the movie as reference.Next, in the portrait making process, we can find some multi-angle life photos or portraits of Henry Cavill, which is convenient for us to observe the structure and capture the shape.!Collection of reference Model SculptingIn the modeling process, we need to set the size and proportion of the realistic character model at the beginning. Having a realistic scale for reference will help us in the subsequent detailed production, as well as hair and material production.When working on realistic character or orc-like projects, solid anatomical knowledge and sculpting skills are essential. These factors fundamentally determine the depth and quality of our models. Therefore, it is necessary to practice sketching regularly. For example, I also do similar sketching exercises in my daily routine, trying to control each sketch exercise within half an hour with a specific purpose. During the practice, I can use the built-in slice tool in ZBrush as a basic framework. Its size is based on realistic human head proportions, which allows us to practice skull or muscle anatomy. The exercise is shown in the image below:!Model Sculpting of supermanOnce we have acquired a certain level of foundational skills and a wealth of theoretical knowledge, we can use our understanding of anatomy to engage in sculpting exercises for designing orc-like characters.!Model Sculpting of supermanWith a solid foundation and extensive knowledge of anatomy, when working on character designs like this, we can analyze the anatomical structures of the human, animal, or orc-like creature in a rational manner during sculpting. Mastering the anatomy of the head, body, or other forms allows us to analyze and refine the design in a logical way. For example, in the case of this orc head model, as shown in the image below:!Model Sculpting of supermanThere is actually no difference in terms of muscle structure between his face and a realistic human. We analyze it rationally because it has a different skeletal structure from a human's, and its facial features have distinct shapes, resulting in noticeable differences in the muscle structure. However, under the overall skeletal framework, their muscle anatomy is the same. It's like the same piece of clothing hanging on different hangers, forming different folds, but fundamentally, its essence remains unchanged. Therefore, the formation of the fold shapes follows certain patterns that can be observed. This requires us to have a solid theoretical foundation to support our analysis.We achieve large-scale detailed sculpting using ZBrush, making effective use of scan-based mesh retopology techniques. For quick mesh symmetry, we directly utilize R3DS Wrap. R3DS Wrap is a professional-grade 3D topology tool software that has revolutionized the way we handle 3D scan data. When working with human scans or similar subjects, existing basemeshes can be loosely matched to each scan. It also provides a set of highly useful scan processing tools such as decimation, mesh filtering, and texture projection. Thanks to its node graph architecture, once a single scan is processed, the same approach can be applied to an unlimited number of other scans. Mapping of CharacterAfter completing the high-resolution sculpting of the body, we use Mari to start creating the skin texture channels. The overall workflow is quite simple, and I'll briefly describe it.For color painting, we utilize XYZ scan materials and wrap them using the ZWrap plugin, which serves as a realistic texture base. Then, in Mari, we make adjustments and add details to the projected textures. We overlay multiple color biases on the color map to achieve a rich color effect. Since gorillas have black skin, the details we paint or obtain from XYZ materials may not be clearly visible. Therefore, we add a layer of lighter color contrast to enhance some details.!Mapping of SupermanWhen creating roughness and specular maps, we need to pay attention to the variations in highlight levels and roughness intensity. The highlight map can be created by inverting the colors of the roughness map and then making adjustments accordingly. For the complete set of skin texture maps, I have created the color, specular, roughness, and SSS (Subsurface Scattering) strength and color maps.!Mapping of Superman Production of ClothingFor clothing production, I primarily rely on Marvelous Designer for fabric simulation and utilize ZBrush for quick sculpting and refinement.Marvelous Designer has become widely used in CG art production. Therefore, it is essential for us to learn and master the basic usage of this software.I am not particularly skilled in using Marvelous Designer myself. I am only familiar with its main function of fabric simulation, which assists in model creation. To create realistic clothing patterns, it is necessary to have a basic understanding of garment cutting theory, especially for formal or workwear attire. Details such as waist openings or cuff offsets can affect the final result of fabric simulation. For unique designs, we can refer to existing paper patterns as references.!Production of Clothing Of course, when working on the Superman costume, I didn't follow such strict procedures. Since it is a form-fitting suit, I directly created the base mesh in ZBrush and imported it into Marvelous Designer for fabric simulation and folding. Marvelous Designer can quickly assist us in achieving small wrinkle formations around muscle compressions and structural transitions. It is very convenient to use in this regard.!Production of Clothing of SupermanThe process of creating textures for clothing is relatively simple. I directly imported the model into Substance Painter and used a tiled texture as the fabric pattern for the garment. Then, I assigned a base color and added some procedural textures as needed. To achieve the desired fabric texture effect, I adjusted the material nodes in Maya, which provides similar results.!Production of Clothing of Superman Production of MaterialsCreating materials for skin is very straightforward. The surface material effect in Arnold can directly present a very natural and realistic result. When adjusting the skin material nodes, it is important to note that the value of surface scale is influenced by the scene's scale, and it should complement the color of the radio to achieve the desired effect. When tweaking the parameters, it is helpful to enable real-time rendering to observe the effects while making adjustments.!Creating materials for skin Production of HairWe use XGen for hair styling as it is a widely-used and highly effective tool for creating hair in the industry.Traditional XGen provides high control and flexibility over the styling of hairs, allowing us to meet most of our requirements. When working on the guide hairs, we need to pay attention to the hierarchy and even distribution of the guides. We can also utilize masking painting and the addition of modifier nodes to achieve different hair descriptions and styles.!Production of Hair of SupermanAbove is the main process of making the 3D version of Henry Cavill Superman. The next steps are material rendering and connecting each part, which will not be explained in this article. We hope this article is helpful to you.Source: H cheng

In 2009, a sci-fi film Avatar swept the world. This film won a lot of honors, but as a CG enthusiast, the greater fun is still exploring the production process of this film. In Avatar, many characters and scenes are made using Maya. As the leading cloud rendering services provider and render farm, Fox Renderfarm will introduce the Avatar as a case by Arnold and Maya to introduce the software. Part 1. Collection of materials Material collection is an important step, and the more time you spend collecting material, the less late errors will be. When making the Avatar model, I used the web to collect a lot of real material and video reference. You can add some of your own understanding during the production process. You can also try different brush strokes when post-production in ZBrush, and finally unify the whole character. Here are some of the materials I collected. Part 2. Maya basic modelUse Maya's own box as the basic model, first adjust the general proportion, and then start from the large-sized model parts, so that you can grasp the overall feeling of the character in a relatively short time, and easily modify the scale. As far as possible, the wiring should be as clean as possible. It is not necessary to describe too much detail. In particular, pay attention to the structural turning of the head to facilitate engraving later. Step 1: This role, gives me the feeling is a combination of feline and human face, the upper part of the face is a lion, the lower part is a human. I decided to put more effort into her lower half of the face and tried to understand the upper half of the cat's face. After analyzing these things, we can grab some of her characteristics to start modeling. I made a simple model, this time there are very few lines, it is very convenient for you to adjust the feeling. At this time, the proportion and position of the character's lower jaw and facial features were fixed. Step 2: Add one line while adjusting and perform local detail processing. Eye, eyebrow and cheekbones, here are the low mold and final wiring diagram. Part 3. Adding ZBrush DetailsAccording to the previous reference to determine some of the details of the role structure, subdivision in ZBrush, improve the number of faces of the model to add some details to the model. For example, pores, texture of the lips, etc. Step 1: First perform Maya's cleanup to check if there are more than four sides. Export the obj model without problems. Step 2: Import ZBrush to add details. Use a few skin brushes. Detail breakdown and detail addition. Part 4. Mapping the TextureBecause there is already a film and television as a reference, the texture is closer to the content of the film. Here are some of the material I collected. You need to make sure the uv is correct before drawing the texture. I am using the UVLayout plugin to split the model UV. Pay attention to the position of the tangent at the time of splitting, try to put it in the place where it can't be seen, so as to avoid the seam problem. The mapping of the texture here is made by combining Mari and ps. In order to quickly grasp the process of drawing textures using mudbox here. These are the uv splits using plugins. It's worth noting that sometimes splitting out is not ideal and needs to be re-edited in the Mayauv editor. The overlapping parts in the red part of the figure can be adjusted in the uv editor. The final result is as follows. After the UV editing is done, it is necessary to draw the texture and draw it here using the mudbox.Firstly, subdivide the model and then export obj. The second is to open the mudbox and import the model. Select a brush. The shader looks at your personal habits and can switch between viewing highlights and non-highlights. Select the brush and click New Layer on the model to select the map size and format as needed.I am here to choose 4096*4096 size for clarity. And named as the background color, in order to put the background color on the model, to prevent the back when painting the map. The new layer adds the pattern, which can be adjusted in conjunction with the layer blending mode. To achieve the right results. Generate textures and export them after making multiple adjustments. And add textures in ps. And the root layer is created to generate the corresponding 3s highlights and bumps. Part 5. RenderingLight setting: The first step, we basically use the most basic three-point lighting principle to first adjust the intensity of light to achieve the required intensity. Note that this is the arnold renderer that is utilized, so the default light is attenuated with light. The lighting test of the advanced model (the model without the map) pays attention to the contrast of the cool and warm of the light.The three-point lighting is generally the primary light source auxiliary light and contour light, pay attention to the contrast between the main light source and the contour light. There is also an application with skydemo light to simulate the surrounding environment. Setting of the shader ball: In order to better express its texture and skin characteristics, we will use the corresponding skin material.The first step: Since the texture has been drawn before, the respective skin layers whose inherent color is blue are also adjusted according to the inherent color. Connect all the textures to the corresponding properties of the shader and adjust the parameters. Here, five textures are connected to the skin's three-layer highlight and normal map. Then adjust and test the lights. Render channel output: Render the corresponding channel, which is more convenient to adjust later. They are id, normal, highlight, ao, sss, etc. Channel synthesis: The rendered layer is synthesized in ps, the ao channel is synthesized by the method of the film stacking, and the highlight channel is synthesized by the screen method. The normal channel can be synthesized in nuke to re-adjust the light. It is possible to directly adjust the eyelashes and adjust the background lighting effects and color in the ps. Adjust the desired effect with the final adjustment. That's all there is to explain about the making of Avatar, we hope you've been inspired.
