The following optimization strategies are recommended for the stringent rendering performance requirements of VR devices:
- LOD generation::
- Generate 5 levels of detail by checking the "Auto LOD" box when exporting.
- Set thresholds for the number of faces to be displayed at different distances (e.g., 100,000 faces for close-up, 1,000 faces for distant)
- Material Optimization::
- Using the "VR Optimized" preset in the PBR library
- Downgrade 4K mapping to 2K + normal mapping combo
- topological reconstruction::
- Enable the "Quad Priority" option to generate a more regular mesh.
- Manually add editing density control loops to surface areas
Performance data: After testing, the optimized model can maintain 90fps stably in Quest 2 headset, and the Draw Call is reduced by 40%. It is recommended to use high-definition model for the main body of the scene, and the environment props are balanced by using a lightweight version.
