To rig mesh 3D models as a student, use beginner-friendly tools (like Blender or Maya LT) to add a simple bone structure aligned with the mesh’s key movements (e.g., limbs, spine), then assign weights to control how bones influence the mesh—focus on simplicity to build foundational skills.
Rigging links a "skeleton" (bones) to the mesh so it can animate—start with basic projects (e.g., a stick figure or moving cube) to practice bone placement without complex details.
Use auto-weighting tools (such as Blender’s "Automatic Weights") for quick setup, then tweak weights manually with the Weight Paint tool if parts don’t move correctly (e.g., an arm not following its bone)—this helps you learn how weights affect mesh movement.
