The release of Lumion 2025.1 marks a significant shift for architects, focusing on the launch of Lumion Cloud
, a new web-based platform for seamless collaboration and design reviews. This "hot" update builds on the core 2025 version, which introduced AI-powered upscaling for 8K renders and ray-traced volumetrics. The Story of a Render: From Blueprint to Cloud
It was 2:00 AM, and Marcus sat before three glowing monitors. His client, a high-stakes developer in London, wanted to "feel the atmosphere" of the new Residence 8445 project before the morning board meeting. Marcus opened Lumion 2025.1 . He didn't just want a photo; he wanted a story. The Foundation
: He imported his 3D model, its surfaces flat and lifeless. Using the Ray Tracing
pipeline, he applied the new Water Material to the infinity pool. Instantly, the water didn't just sit there—it caught the reflection of the surrounding photogrammetric trees with liquid realism. The Atmosphere : Marcus added Ray Traced Volumetrics
. A soft, morning mist began to cling to the garden, catching the low-angle sunlight in a way that looked like a cinematic film rather than a computer simulation. The Detail : With the new Mirror Object
function, he quickly duplicated the ornate lighting fixtures across the terrace, saving precious minutes. He ran the AI-powered upscaler
, transforming his standard render into a crisp 8K masterpiece that highlighted every grain of stone in the PBR materials. The Handover
: In previous years, Marcus would have spent an hour uploading a massive file to a slow server. Now, with Lumion Cloud
, he clicked "Upload" directly from the interface. By the time he closed his laptop, his client already had a link to the Lumion Cloud
portal, ready to review the render on their tablet before the sun was even up.
For Marcus, 2025.1 wasn't just an update; it was the end of the "exporting" nightmare and the beginning of real-time collaboration. for Lumion 2025 or see a list of the new nature assets

Lumion 2025.1 focuses on refining the major ray tracing and AI foundations introduced in the initial 2025 release. Released in late April 2025, it emphasizes high-resolution rendering speed and atmospheric realism. Key Features and Updates
AI Upscaling: One of the most significant additions, allowing users to render at lower resolutions and upscale to 8K. This dramatically reduces render times for high-quality final outputs.
Ray-Traced Volumetrics: Sunlight and fog are now fully ray-traced, providing accurate light scattering and realistic atmospheric depth that interacts correctly with the environment.
Advanced Water and Glass: Building on previous iterations, Lumion 2025 features fully ray-traced glass and water, delivering more cinematic reflections and refractions.
Scene Inspector: A new management tool that offers a branching list of all placed assets, making it easier to organize complex scenes by layers and categories.
Performance Monitoring: An improved on-screen monitor now tracks VRAM (Video Memory) and RAM usage in real-time, helping users optimize scene density to avoid hardware crashes.
Lumion View for SketchUp: A lightweight "design companion" that allows for quick path-traced iterations within the SketchUp environment before a full Lumion import. Asset Library Additions The library has expanded to over 10,000 assets, including:
Nature: Mediterranean-specific vegetation and photogrammetry-scanned trees for ultra-realism.
Functional Objects: New assets for educational and children’s spaces, such as kindergarten furniture and characters.
Object Flipping: A long-requested utility feature that allows you to mirror or flip any object directly within the interface. Workflow and Performance Is Lumion 2025 Worth It? | Features, Pricing & Workflow
Lumion 2025.1: The "Hot" New Update for Architectural Rendering Unlike a major point update (e
The architectural visualization world is buzzing with the release of Lumion 2025.1, a substantial update that significantly expands the software's ecosystem through cloud integration and AI-driven performance. Whether you are a long-time user or looking to upgrade from older versions like Lumion 12, this latest iteration introduces "hot" features that redefine how architects collaborate and present their designs. The Headline Feature: Lumion Cloud
The most significant addition in the 2025.1 update is the launch of Lumion Cloud.
Seamless Sharing: Architects can now upload Photos and Panoramas directly from the Lumion interface to a secure, browser-based platform.
Collaborative Feedback: This feature is designed to replace the aging MyLumion service, allowing team members and clients to review renders and provide feedback without needing the full software installed.
Direct Integration: Lumion Cloud integrates with Lumion View, a standalone real-time visualization tool for SketchUp and Revit. Cutting-Edge Performance: AI and Ray Tracing
Lumion 2025 has moved closer to photorealism by doubling down on hardware-accelerated ray tracing and AI tools.
AI Image Upscaler: A standout "hot" tool that intelligently boosts render resolution up to 8K while enhancing fine details like brick textures and leaf edges.
Fully Ray-Traced Water and Glass: Previous versions used approximations; Lumion 2025 features fully ray-traced water materials that accurately refract light and reflect the environment.
Radiance Cache: This new system improves real-time preview quality, reducing the flickering and "blotchy" artifacts often seen in darker, indirectly lit interior scenes. Workflow & Productivity Boosts Latest Features and Improvements of Lumion 2025
Lumion 2025.1, released on 26 August 2025, is primarily a collaboration-focused update centered on the launch of Lumion Cloud. While it includes critical stability fixes, user sentiment remains mixed regarding the speed of innovation compared to its competitors. Key Features & Changes
Lumion Cloud Launch: A major new web platform for sharing designs, gathering client feedback, and secure collaboration directly from the software.
Ray Tracing Fixes: Resolves a specific crash issue caused by NVIDIA driver version 580.88 and higher. It also fixes blurring effects on oceans near coastlines.
Mandatory Login: All users are now required to sign in to their Lumion Account on the first startup to access cloud services. UI & Workflow Tweaks: Replaced pagination in the Effect List with a scroll bar.
The "Build with Effects" button moved to the Sidebar Menu. New presets added to the RT Volumetrics Effect.
Sunsetting MyLumion: Lumion Cloud officially replaces MyLumion; new uploads to the old service are no longer possible in this version. Critical Reception & User Reviews
Performance vs. Competition: Professional reviews and community feedback highlight that while Lumion remains a leader in interface design, it is increasingly viewed as "expensive" compared to D5 Render and Twinmotion.
Unfinished RT Features: Users have expressed frustration that critical Ray Tracing (RT) features—such as RT grass, RT shadows on moving objects, and 8K native resolution (relying instead on an AI upscaler)—are still missing or underperforming. No new major features — just a smoother,
Installation/Login Issues: Some users reported "session timeout" errors and difficulty signing in through web browsers, which can block access to the software during tight deadlines.
Stability: The update is noted for fixing persistent crashes when switching to Ray Tracing effects in large project files. Technical Requirements & Compatibility
Installation: This version originally required a full installation rather than a simple patch update for users on versions older than 2025.0.2.
Backward Compatibility: 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?
