To make a bottle 3D model look clean, prioritize three core elements: smooth surface topology, realistic material settings, and soft, even lighting—these ensure the model is clear and free of imperfections.
- **Smooth Topology**: Avoid jagged edges or messy polygons. Use tools like Blender’s Loop Cut to add even edge loops, so the bottle’s curves look polished instead of rough. - **Realistic Materials**: Adjust reflectivity to match the bottle’s material. For glass, set roughness to 0.05–0.2 for subtle gloss; for plastic, use a matte finish to prevent muddiness. - **Soft Lighting**: Use diffused light (like a softbox or area light) to reduce harsh shadows and noise. This keeps the model looking crisp and professional.
Small tweaks in tools like Blender—such as refining edges or adjusting material sliders—can make a big difference in how clean the model appears.
