What Is an AI Rigging Tool?
An AI rigging tool uses highly intelligent automation, algorithms, and machine learning to significantly speed up and simplify the character rigging process. Rather than a fully autonomous AI, these tools excel at specific tasks like landmark detection to identify key points on a 3D model, automatic bone placement to generate a skeleton, intelligent weight painting to distribute skin weights, and control rig generation to create user-friendly controls for animators. They have become indispensable in animation and game development, saving countless hours for artists by automating one of the most complex and time-consuming parts of the 3D pipeline.
