To bake high poly 3D models for mobile performance, use a low-poly proxy mesh to transfer key details (via normal and ambient occlusion maps) and optimize textures for mobile GPUs—this moves heavy geometry work to lighter maps, so your model runs smoothly on mobile.
- **Focus on essential maps**: Use normal maps (for depth) and ambient occlusion (for soft shadows) to transfer high-poly features (like cracks). Skip unnecessary maps to save memory. - **Use mobile-friendly tools**: Blender or Substance Painter have presets for mobile baking, making it easy for beginners. - **Optimize and test**: Keep textures under 2048x2048, use compressed formats (ASTC/ETC2), and test on actual devices to balance quality and speed.
This approach retains high-poly detail while creating a lightweight model that performs well on mobile.
