What are effective techniques for optimizing high-poly models for real-time use?
Asked on Feb 01, 2026
Answer
Optimizing high-poly models for real-time use involves reducing polygon count while maintaining visual fidelity, ensuring efficient performance in real-time applications. This process is crucial for achieving smooth rendering in environments like games or VR.
Example Technique:
- Step 1 – Retopologize the model to create a clean, low-poly mesh with efficient edge flow.
- Step 2 – Bake high-poly details into normal maps to preserve surface detail on the low-poly model.
- Step 3 – Optimize UV layouts and use texture atlases to minimize draw calls and memory usage.
Additional Comment:
- Use LOD (Level of Detail) models to switch between different resolutions based on camera distance.
- Consider using decimation tools to automate polygon reduction while maintaining essential shapes.
- Ensure the final model maintains proper scale and proportions for the intended real-time environment.
