When modeling complex organic shapes, topology is handled by prioritizing edge flow that follows the shape’s natural contours and structural lines, ensuring smooth deformation, efficient rendering, and ease of sculpting or animation.
Key practices include: using quad-dominant meshes to maintain clean geometry; aligning edge loops with movement areas (e.g., joints, curves) to support deformation; and managing poles (vertices with >4 edges) to avoid distortion.
Additionally, if starting from a sculpt, retopologize to optimize edge flow; for initial modeling, block out major forms first, then refine topology gradually to balance detail and structure.
