: Projects saved in 2025.1 cannot be opened in older versions like Lumion 2024 or 12.5 due to significant changes in file data structures . How do you get the latest Upgrade or Update of Lumion?
This controversial feature uses local AI processing to upscale 2D textures to 8K on the fly. Why "hot"? Because it causes significant VRAM spikes. Users with 12GB GPUs or less report "out-of-memory" errors when enabling this for more than 15 materials.
The standout feature of Lumion 2025 is the massive leap in its Ray Tracing (RT) capabilities. While previous versions introduced the tech, Lumion 2025 perfects it. The new RT engine handles complex light bounces with incredible accuracy, virtually eliminating the "blotchy" artifacts seen in older real-time renders.
, allowing for more natural light behavior, reflections, and shadows. This technological leap is complemented by the inclusion of ray-traced volumetric effects
: Water materials now support full ray-traced reflections, refractions, and global illumination, while new volumetric fog reacts naturally to light beams for more cinematic atmospheres.
: Building on the ray-tracing engine introduced in earlier versions, 2025.1 adds convenient presets for ray-traced sun and fog effects, making it easier to set atmospheric moods quickly. Material and Phasing Tweaks
