For LOD low poly 3D models, the best manual retopology balances silhouette accuracy, minimal polygon count, and compatibility with UV mapping/animations.
- Prioritize key details: Keep essential shapes (e.g., character facial features, prop edges) while removing non-essential geometry (small creases, flat surfaces). - Align with UVs: Match edges to UV seams to prevent texture stretching. - Optimize movement areas: Use fewer edge loops in low-movement spots (e.g., back of hands) to save polygons without losing quality.
Start with the highest LOD model, use edge collapse tools, and check the silhouette regularly to keep the model recognizable.
