When skinning a topology 3D model as a beginner, follow four core steps: prepare clean, quad-based topology, bind the model to a rig, weight paint vertex-bone influences, and test/adjust for natural deformations.
Clean topology (no triangles/ngons) ensures even edges so weights apply smoothly. Binding links the model to a skeleton—use auto-rig tools (like Blender’s Rigify) for simplicity. Weight painting uses a brush to assign influence (white = full, black = none), focusing on joints for gradual transitions. Testing involves moving bones to spot stretching/clipping, then tweak with soft brushes.
If using Blender, start with Rigify for a pre-made rig—it simplifies binding, and use the “Smooth” tool in Weight Paint mode to fix harsh edges easily.
