To skin humanoid 3D models for games, use 3D software (e.g., Blender, Maya) to attach a skeleton (armature) to the model, then assign vertices to bones via weight painting—this ensures natural deformation during animations (like walking or jumping).
Here’s the core process: - **Rig the skeleton**: Build a hierarchical armature matching human anatomy (spine, limbs) to act as the model’s "movement structure." - **Weight paint**: Use tools to set how much each bone influences nearby vertices (e.g., more weight on the forearm for wrist movement) to avoid tearing.
For beginners, start with Blender’s pre-made humanoid armatures—practice weight painting on simple poses before creating custom rigs to perfect deformation.
