Arnold for Maya Tutorial: How to Render Wireframe

Arnold for Maya Tutorial How to Render Wireframe

When making some work, we need to render some special effects, such as only showing the wireframe of the model. In this article, Fox Renderfarm, your best cloud rendering service provider, will show you how to use Arnold for Maya to render the mesh, show the model in wireframe or show the individual wireframe alone.

Arnold renderer

First, you need to modify the settings in the Arnold renderer, and then open the Hypershade to select the shader aiWireframe, the shader that implements the wireframe.

aiWireframe

Let's look at the properties of the aiWireframe shader, the detailed values: Edge Type is divided into Polygons, Triangles, Patches; Fill Color: This is the colour of the entity of the model itself. After testing, this node is connected to SurfaceMaterial for transparency and masking, but it has no effect, so, the node should be able to accept RGB information. About the LineColor the LineWidth, shown as below,

Settings of aiWriteframe

The setting of this material is used as backup content for later use. We use this node as transparency information, to link the rendered material transparency node. We add the basic Arnold shader aiStandarSurface to the model to be rendered, and we can choose to adjust the colour in the basic shader.

The key step is to connect the aiWriteframe shader we made earlier to the Opacity node of the basic shader.

Next, we need to remove the Opaque node from the basic attributes of the model. A model can easily adjust the Opaque node in Arnold. But if there are many models, it will waste a lot of energy and time to adjust each model in turn.

In Maya, you can adjust multiple model attributes at the same time through the attribute bar.

Remove Opaque in the attribute

The method of batch adjustment of model attributes is in the AttributeSpreadSheet of GeneralEditors under windows. The detailed selection of the attributes of the model is to render the first AIOpaque in the Arnold window, and then click to enter 0. 0 is off and 1 is on here.

Modify model properties in bulk

Let's take a look at the test results. The picture on the left is the rendered reb colour effect, and the one on the right is the effect with channels.

So, regarding the grid now that it can be displayed transparently, how to achieve a mask effect that blends transparency and opacity?

First, use the same method to make the first shader, and then use Maya’s most primitive basic shader: surfacesShader, this can control the masking effect very well, we use the made aiWireframe to link the Out Color of the surface shader so that we can achieve the transparency effect of the mask.

You can see the masked transparency effect below,

Basically, this is how it is made. Of course, you can also use this method to make other effects. Hope to help you.

How to Make Realistic Characters in ZBrush and Maya(2)
How to Make Realistic Characters in ZBrush and Maya(2)
The best render farm Fox Renderfarm still shares with you the post about how to make realistic characters in ZBrush and Maya from 3D artist Yi Chen, and this is part two. Yi Chen showed us the workflow of his latest realistic female character. Software used includes ZBrush, Maya, Mari, Substance Painter, Xgen, Arnold, etc. About part one, please click here. Texturing After the high polygon model was carved, I re-split the model's UVS into 6 UVIDs and changed it to 4K accuracy. This step is mainly to draw textures in Substance Painter and also to ensure that the high-poly displacement details will not be lost in the final rendering. If you are using Mari to draw textures, then I recommend using 2 sheets of 8K accuracy. Before using Substance Painter to paint colors, we can still use Zwrap to use some scanned model textures as background colors to improve work efficiency, and then further describe the colors and details of various areas of the face based on it. In this step, I drew the Base Color, Specular, and Thinkness maps. The Thickness map will be used as the weight map of the SSS skin to locally control the intensity of the skin subsurface scattering. Please look forward to the process of material setting and lighting rendering next time. Thank you for watching.

How to Make Realistic Characters in ZBrush and Maya(1)
In this post, the best render farm Fox Renderfarm will share with you a tutorial about how to make realistic characters in ZBrush and Maya from 3D artist Yi Chen. Yi Chen showed us the workflow of his latest realistic female character. Software used includes ZBrush, Maya, Mari, Substance Painter, Xgen, Arnold, etc. This is part one of the tutorial, part two will be continued. Introduction I am a 3D artist. Today I will share the production process on how to create realistic characters. The model is made using Zbrush and Maya; Mari and Substance Painter are used to make textures; Xgen is used to make hairs, and Arnold is used for rendering. A Male character: Gathering references Before starting to make the model, I will analyze the concept map and collect a lot of pictures of women. Because this work does not refer to a specific picture, I could combine and match many of your favorite elements, including clothing, hairstyles, makeup, jewelry, etc. Then starting with simple sketching and compositing in Photoshop, it is better to have a concept map at least before production. Modeling I’m used to determining the size and scale of the model before making the model. According to Anatomy, the vertical length of the head of an adult is between 22-24cm, and the diameter of the eyeball is generally between 2.4-2.5cm. And when making a model in Zbrush, we need to set the focal length of the Zbrush view camera in advance according to the picture material. The most commonly used portrait focal lengths are 85mm, 100mm, 135mm, and 200mm. Some original photographs usually include the specific focal length value of the picture. If it is a reference picture, we can roughly determine the focal length range by observing the leakage range of the front person’s ears. The gif below can be used as a reference basis. Of course, this is only a reference for the focal length of a portrait. If it is half-length or full-length, the focal length will be different. To create the model based on the reference material, I directly used Zbrush to sculpt Blocking, and the number of subdivided faces was kept at about 50 million, level 7 so that the flow model used for rendering at the lowest subdivision level can be controlled at about 12,000. After the model was modified, I continued to use the UV split tool that comes with Zbrush to make the UV, and then manually adjusted it to the appropriate position. Then I used XYZ pore material + Zwrap plane to project the pores, and then projected some undesirable areas in Mari. Next, it was time to output the grayscale images of the three channels of R, G, and B in Mari and extrude the bumps on the surface of the model through Zbrush to get fine pores. In this step, the model used a 16-bit 8K precision texture map.

Arnold for Maya Tutorial: Ice Cube Material
Arnold for Maya Tutorial: Ice Cube Material
Fox Renderfarm is known as a powerful but affordable render farm in the CG industry. Fox Renderfarm supports most mainstream software, Renderers, and Plugins, including Maya and Arnold. This article is about the knowledge of ice cube material in the basic material related learning in the Arnold tutorial. I hope it can be helpful for your learning of Arnold. In all kinds of texture making, ice cubes are a special kind. The overall texture of the ice cube is transparent, and has high specularity and refraction, as well as a certain caustics. Although the ice cubes are smooth, fine particles can still be seen at a certain angle. These particles are actually some small white bubbles generated during the ice-making process. There are many ways to achieve this effect. Today we will share a method of making ice cubes. Production First create a block to serve as the main body of ice. Then create an Arnold base shader and modify some of the settings. Because the ice cube material is transparent. There is no color, so there is no surface color. In Diffuse, set Color to black. Increase the Weight value in Specular. Because the surface of ice has no roughness and is very smooth, you need to open Fresnel to simulate this effect. Set the refraction, the value of Weight also needs to be adjusted up, the value of IOR is set to 1.33, and then check Fresnel, also need to check Caustics. Now the basic texture of the ice cube has been set. Now you need to add a small bubble effect to the ice cube. First create an Arnold 3D texture material, give the model, the following dialog box appears, just close it. After jumping out of the Aibump3d1sg node, you just need to drag the created Arnold texture to the Surface Shader in Arnold of Aibump3d1sg, then the model will appear small bubbles of bump effect. Next, place the ice texture made in the Shader of Aibump3d1 in the texture. Next, you need to add a Stucco texture map to the Bump Map in the 3D node, and then change the Bump Height to 0.5. Now that the material part is complete, the rest needs to add an HDRI. Open the material editor, create an aiSky environment ball map in Arnold, and paste an HDR environment map in Color. Change the value of Intensity to 2. Some settings are required before rendering. Click the Background link in the Environment to create the aiSky texture that was just created, so that the lights in the scene are set up. The sampling value of Cameraca is increased to 5 (the higher the value, the slower the rendering speed). Refraction value is set to 4. Set the Refraction value to 4 in Ray depth. Create a sphere as an environment and check Visibe in Refiections in Render Stats. Then conduct a rendering test. Rendering In 3D texture mapping, Maya's own 3D texture mapping can achieve many different effects (turn off the highlighter and refraction of the shader, and the following effects appear, The highlight and refraction of the shader are turned on, rendering:
