What are the best manual retopology for reduce high poly 3D models?

When reducing high-poly 3D models, the best manual retopology methods are edge flow-aligned retopology, quad-dominant meshing, and UV-seam-matched retopology—they balance detail preservation and topology control effectively. Edge flow-aligned retopology follows the model’s natural curves (critical for characters/animations to ensure smooth deformations). Quad-dominant meshing uses mostly four-sided faces (easier to edit, render, and rig). UV-seam-matched retopology aligns edges with UV seams (prevents texture stretching in final assets). For beginners, use Blender’s Retopology tools or Maya’s Quad Draw—start with simple objects (e.g., a mug), focus on matching edge flow first, and avoid overcomplicating with small details early on.
