For beginners rigging a 3D model to use with Blender’s Eevee render engine, start with an armature (skeleton) matching the model’s structure, link the mesh to bones via weight painting, and test poses for natural movement.
Build the armature: Add bones for key parts (spine, limbs) and align them precisely with the model’s mesh—this skeleton drives all movement.
Link mesh to bones: Use Blender’s "Automatic Weights" to parent the model to the armature. Refine weight painting next: paint red on areas a bone should move (e.g., forearm) and blue on areas it shouldn’t to fix stretched joints.
Test & adjust: Pose the armature often to check for unnatural deformation. Tweak weights or bone placement if parts look distorted.
Keep it simple: Start with basic models (5-10 bones, like a cartoon character) and use Blender’s Rigging workspace tutorials—they guide you through armatures and weight painting step-by-step.
