Spine Animation Skeletal

Spine is a specialized tool for creating 2D skeletal animations using a bone-based (armature) approach. You design a skeleton (bones), attach artwork (skin) to the bones, then animate by moving bones over time. The skin deforms around the bones, creating smooth animation with minimal file size. Spine animations are widely used in indie games, mobile games, and professional game studios. It's the industry standard for 2D skeletal animation.
