How to Rig a 2D Model for VTuber
What is a VTuber?
A VTuber is a virtual YouTuber, or a character that performs in online videos. They have become increasingly popular in recent years, with many VTubers gaining millions of followers. VTubers are typically animated characters, and they are created using 3D models or 2D sprites. While 3D models are more commonly used, it is possible to rig a 2D model for use as a VTuber.
What is Rigging?
Rigging is the process of creating a skeleton for a 3D model or a 2D sprite. The skeleton, or “rig”, is used to animate the character and give it the ability to move. In order to create a 2D rig, the model must first be broken down into individual parts. This can be done by separating the head, body, arms, and legs into separate layers.
Creating the Rig
Once the model is broken down into separate layers, it is time to create the rig. The rig consists of a series of “bones” which will be used to control the movement of the character. The bones can be created using a vector drawing program, such as Adobe Illustrator or Inkscape. When creating the bones, it is important to keep in mind the character’s natural movement. For example, when creating the arm bones, it is important to remember that the arm can bend at the elbow and rotate at the shoulder.
Adding the Control Points
Once the bones have been created, it is time to add the “control points”. The control points are small circles which are used to control the movement of the bones. These control points should be placed so that they are in line with the natural movement of the character. For example, if the character’s arm can bend at the elbow, the control point for that joint should be placed at the elbow.
Animating the Character
Once the rig is created and the control points are in place, it is time to animate the character. This is done by using the control points to move the bones. For example, if the control point for the elbow is moved, the arm will bend at the elbow. The same principle applies to the other joints, such as the shoulder, hips, and knees. By moving the control points, it is possible to make the character move in a realistic way.
Adding Special Effects
Once the character is animated, it is possible to add special effects. This includes things like facial expressions, lip syncing, and particle effects. These effects can be added using a vector drawing program or a 3D animation program. By adding these effects, it is possible to give the character a more dynamic and realistic look.
Conclusion
Rigging a 2D model for use as a VTuber is a relatively simple process. By breaking down the model into individual parts, creating the rig, adding the control points, and animating the character, it is possible to create a realistic and dynamic VTuber. With the right tools and knowledge, anyone can create their own VTuber.
