✔ Use Sunlight as your main light ✔ Limit Omni lights (very heavy) ✔ Use Spotlights only where required ✔ Turn off shadows for small lights (big optimization!)
✔ Keep only 1–2 reflection planes ✔ Avoid placing them on every glass surface ✔ Use SpeedRay reflections instead of full reflection planes
—
⭐ 4. Optimized Output Quality
For fast rendering:
Render Settings → Output Quality
720p → fastest preview renders
1080p → balance quality + speed
Turn off Hyperlight (very heavy)
Set Shadows → Medium
Set AA → Low/Medium

⭐ 5. Reduce Landscape + Grass Load
Grass uses GPU heavily.
✔ Use Low Grass Density ✔ Replace “Fine-detail Nature” objects with simple ones ✔ Avoid large areas of 3D grass — use texture grass instead
—
⭐ 6. Use GPU-Friendly Models
Some imported models have millions of polygons.
✔ Use “Optimize Model” on import ✔ Avoid high-poly furniture (replace with Lumion assets) ✔ Convert large landscape objects to billboards if possible
—
⭐ 7. Use Proxy Objects During Editing
Lumion has a feature:
Build Mode → Replace High-Detail Assets with Proxies
This increases editor FPS dramatically.
—
⭐ 8. Turn Off Effects Until Final Render
Heavy effects:
Hyperlight
Real Skies
Rain/Snow
DOF
Motion Blur
Lens Flare
Shadows Ultra
➡ Keep them OFF while working. ➡ Turn ON only during final render.
—
⭐ 9. Use Balanced Camera Paths
In animations: ✔ Keep simple paths ✔ Avoid too many keyframes ✔ Don’t mix too many effects in a single clip
—
⭐ 10. Hardware Optimization
Even low-PC users can optimize:
✔ Keep background apps closed ✔ Make sure GPU is set to High Performance in Windows ✔ Update GPU drivers ✔ Enable NVIDIA DLSS (if available)
