Tips and Tricks for creating realistic hair and fur for 3D characters in Maya

For graphic designers, creating realistic hair and fur for 3D models in Maya can be both a difficult and gratifying undertaking. While hair and fur can give your characters a great deal of individuality, detail, and realism, they must also be carefully planned, modeled, texturized, and rendered. This blog will teach you how to use the Arnold renderer and the XGen Interactive Grooming tools in Maya to produce hair and fur.

Let’s get started!

Maya is a professional 3D graphics and animation software developed by Autodesk. Maya is widely used in the entertainment, film, television, and gaming industries to create 3D graphics, animation, special effects, simulations, and many other applications.

In Maya, “fur” and “hair” are both used to create realistic and complex simulations. When used together, they can create detailed and realistic characters. Fur creates whiskers, eyebrows, and other facial features, while hair is used for the character’s main hairdo. In Maya’s Fur and Hair systems, users can control the length, shape, color, and texture of these features. This allows for greater control and realism in the animation process. Digital artists can use these tools to bring their characters to life in a more detailed and realistic way.

Maya Fur lets you create realistic, self-shadowing fur and short hair on multi-surface NURBS, polygonal, and subdivision surface models.

Consider using the XGen interactive grooming brush-based tools and modifiers to create and style hair, fur, and feathers for characters. 

XGen Interactive Grooming is a powerful tool in Autodesk Maya that allows users to create and edit hair, fur,  and any hairstyle directly in the Maya viewport with ease and flexibility. It is a great tool to create natural and realistic hair and fur for your character or 3D model.  Interactive Grooming is a mode of XGen that allows you to sculpt and style hair and fur directly on your character using brushes and modifiers. To use XGen Interactive Grooming, you need to have a polygon mesh as a base for your hair or fur, and then create a description that defines the parameters of your hair or fur. You can access the XGen Interactive Grooming tools from the Generate menu or the XGen shelf. 

Hair and Fur Modeling

You can create hair and fur clump maps using the Clumping modifier. Clumping modifiers lets you generate regions on the surface that pull spline tips together to form clumps. 

When creating a clumping map, you specify:

• The location of the clumps and clump guides using a points map.
• The areas that each clump guide affects using a Ptex map, region map, or another clumping map.
• Clumping attributes using slider controls, Ptex maps, or expressions.Use these methods to set the strength of the clump, noise, and more.

Hair and Fur Texturing

You can use the XGen Expression Editor to create custom expressions for your attributes, such as color, width, density, and clump. Additionally, you can paint maps for your properties, such color, breadth, density, and clump, using the XGen Interactive Grooming maps. Also, you can use the XGen Interactive Grooming Paint Effects tool to convert your maps to Paint Effects strokes, which you can edit further using the Paint Effects tools.

Hair and Fur Rendering

Hair and fur rendering in 3D is a critical phase for achieving realism in modeled strands. Arnold is a high-quality renderer that supports XGen hair and fur natively. You can use the Arnold Render Settings to adjust the settings for your hair and fur, such as samples, anti-aliasing, hair shader, and AOVs. You can also use the Arnold Render View to preview your hair and fur in real time and tweak the settings as needed. Additionally, you may apply post-processing effects like shine, depth of field, and motion blur to your hair and fur by using the Arnold Render Filters.

Tips and Tricks

It’s important to follow certain guidelines and best practices while creating realistic-looking hair and fur in Maya. For instance, examine the form, hue, and movement of actual hair and fur by using reference photos and films. Additionally, layers and groups can help organize descriptions and modifiers.

Moreover, the direction and dispersion of fur and hair can be regulated by using regions and guidelines. Furthermore, properties can be made to vary and contrast by using masks and expressions. Presets allow you to save and load styles and settings, while XGen Interactive Grooming sculpt layers allow you to store and edit many versions of your hair and fur.

iRender is the greatest choice for your Maya pipeline whether you’re searching for a render farm or cloud rendering solution. You can use the remote workstation(s) that we offer at iRender just like a regular computer.

iRender provides high-configuration dedicated servers (physical computers/machines) specifically optimized for GPU rendering. Using our service, you will completely control the server(s) you rent through the Remote Desktop application. Therefore, you can customize your creative working environment as you wish. In short, iRender’s server is like your computer in the cloud accessible on any device instantly. You will use its full power for everything. iRender provides useful features to help you switch among the server’s configurations without having to reinstall anything. You can even run multiple servers simultaneously to speed up the renders, not having to re-install anything, either.

Maya often come with third render engines like Redshift, Octane, V-Ray, Arnold, etc.. Whether or not you use any of those render engine, you still can find a suitable package at iRender. Especially, if you use Maya with Redshift, you can access our remote servers and use our Redshift license for free. For Maya, please install and use your license to render yourself.
