In 3D modeling and animation, a jiggle bone is a type of virtual bone added to a character's skeleton to create dynamic, secondary motion. Unlike standard bones, jiggle bones are governed by physics-based simulations, allowing attached parts - like hair, tails, or clothing - to move and react naturally to character movement or environmental forces. While primarily used in game development and animation, jiggle bones can pose a cybersecurity risk if exploited in malicious game mods or custom content, potentially leading to code injection or unexpected behavior. Awareness of such risks is important for secure game modding and content creation.
