This "Sphere-head" character is intentionally kept flattened and cube-like to make it easy to edit, sculpt, and customize, including a simple armature to customize or reuse to be able to transfer animations between multiple models with the same topology, weights and bones!
It is designed as a template, allowing you to freely adjust proportions to suit your needs. The mesh uses approximately 3k quads, keeping the polygon count relatively low while maintaining efficient topology.
The topology is optimized for extensive deformation and motion, allowing for a wide range of rotation without requiring high poly density or a complex armature with many bones.
The legs can be raised all the way to the head with full 360° rotation, and the arms are capable of wrapping around the back with high flexibility and no artifacts despite being low poly.
This makes the model suitable as a base for any character. You are encouraged to modify and edit it, as needed: use freely.
