Rigging is the process of adding bones and joints to a custom VTuber model so that it can move in motion capture software or when streaming live on video platforms like YouTube or Twitch. Depending on the style of animation, rigging can be fairly simple or very complex. Fortunately, new technology and software have made it much easier for even casual virtual tvuber to rig their avatar for basic animation.

To create a 3D VTuber model Rigging, start by designing the character in software like Daz3D. Customize the facial features, hair, body proportions, and clothing. Once you’re satisfied with the design, save it in a file format that’s compatible for rigging (typically FBX). Check that all textures, materials, and morphs are properly applied. Next, export the model to a compatible 3D program, such as Unreal Engine. Then, import the model into your project and verify that it appears as expected.

2D VTuber models, on the other hand, are usually designed using flat art. This type of model is more common with anime tvuber avatars like Kizuna Ai and tends to be more difficult to animate than a 3D model. A good option for creating a 2D avatar is using a combination of Photoshop or other flat-art programs, and then using a specialized rigging and animation tool for flat art called live2D. However, even this can be a bit tricky since many live2D artists do not offer rigging services.

While there are many different software options for rigging a VTuber model, Unreal Engine is one of the most popular choices. It provides robust tools for building and manipulating complex bone structures, IK chains, and control rigs. It also has a built-in physics engine that can be used to simulate realistic movement and interaction. Unreal Engine also allows you to test rigs in real-time, which is crucial for accurately assessing how a VTuber model will behave and perform in various environments.

Another good option for rigging a VTuber models is Live2D Cubism. This program has an easy-to-use interface that simplifies the rigging process. It also supports a wide variety of 3D models and provides features that make it easy to create realistic animations. For example, it offers a range of deformers that can make hair, clothes, and other features look natural when interacting with gravity and motion. It also includes a powerful physics engine that can be used to add realistic interactions to your animations, such as cloth simulation and soft body dynamics.

If you’re working with a professional rigger, be sure to communicate clearly and be specific about your desired results. For instance, if you want to rig your avatar for lip-sync, make sure to provide clear image references for the mouth shapes that you need. Also, be sure to ask about their return/cancelation policy in case you’re not happy with the results.

Once you’re happy with your rigged VTuber model, it’s time to test it in your chosen broadcasting software. Be sure to test the model with a webcam or other tracking device to ensure that it responds to your movements and expressions correctly. If you have any issues with the rig, be sure to contact your rigger and discuss them immediately.
