Lumion 2025.0: Minor updates

 

Lumion 2025.0: Main Release

1. New feature highlights

1.1: AI upscaling

Lumion 2025 brings to the table a new, powerful AI upscaler for Photo Mode that doubles the resolution of images in seconds. 

1.1.1 Enabling the feature: can be done via the toggle above the Photo output resolutions.

1.1.2 How it works: By selecting an Output resolution, Lumion will start rendering an image that is half the size of the desired Photo. 

Once the rendering is finished, it will upscale the image to the selected Resolution and create two files on disk. The first one, is the rendered image (containing '_Original') and the second one is the upscaled image.

1.1.3 Example: You wish to render a Ray-traced image at 8K.

• enable the toggle in Photo Mode for the AI Upscaler
• select the Poster resolution
• Lumion will render a Print resolution image
• the AI Upscaler will generate a Poster image

More information is available here:

• Knowledge Base: How does the AI Upscaler work in Lumion?

 

1.2: Ray-traced volumetric (Beta)

High-quality atmospheric renders can now be created using the new RT volumetrics Effect which allows full control over all surfaces and objects that emit light.

The Effect is placed in the Sky/Weather Category:

1.2.1 Basic controls: can be used to create a uniform application of fog in the Photo/Clip.

1.2.2 Advanced controls: are displayed by clicking 'Show more' and offer more granular control over the elements that create volumetric lighting.

A detailed guide on this feature is covered in the article below:

• Knowledge Base: How do you use the Raytraced Volumetrics: Fog Effect?

 

1.3: Ray-traced water

The Water Material has now been converted fully for the ray tracing pipeline to provide a boost of realism.

Ray Traced Water can be enabled through the toggle in the Ray Tracing Effect, resulting in the full integration of reflections and global illumination.

The details on the new Water Material for Ray Tracing and Rasterization is in this article:

• Knowledge Base:  Water Materials in Lumion 2025 and newer

 

1.4: Radiance cache

Smoother and more refined lighting is added to the Real-time preview using this technique that stores and reuses computed radiance values rather than recalculating them for every ray.

1.4.1 Benefits:

• faster Preview rendering
• reduction of noise
• improved light transportation through early termination of rays
• better global illumination

1.4.2 Practical application:

This is especially noticeable with the way that lights accumulate over time, resulting in a consistent render over time. The example below shows the same preview in Lumion 2024.4.3 vs Lumion 2025.0.0:

 

1.5: Lumion View importing

SketchUp PBR maps and Lumion View Material settings are now imported when loading an .SKP file into Lumion. Lights placed using Lumion View are also imported:

Currently, the feature supports only classic import (via the 'Import model' button). Support for LiveSync import will be added in a later version.

 

1.6: Scene inspector

Lumion 2025.0 comes with this new workflow enhancing feature, designed to increase productivity by easily locating and managing Objects in complex Projects.

1.6.1 Availability:

While in Select Mode (available both in Build Mode and Build with FX), click the magnifying glass button at the top-left corner of the interface.

1.6.2 Feature overview:

• Hierarchy: Objects are organised by Layer, then Category, then Type. As an example, to find an Area Light, you expand the Layer, then the Lights Category, followed by the Area Light type and all Area Lights will be displayed in order.

• 

• Search bar: Typing the name of a Layer, Object, or Imported Model will display the relevant items

• 

• Filter panel: Category filtering can also be applied. An active filter is indicated by the blue dot next to the filter button

•

• Knowledge Base: How do you use the Scene Inspector in Lumion 2025?

 

1.7: Improved performance monitor

1.7.1: The Lumion title bar has been fitted with an improved speedometer that monitors the performance of the Project and displays the frames per second (FPS).

The color changes based on the FPS.

1.7.2: On hover, a detailed Project overview is displayed:

1.7.3: On clicking the speedometer, the window is expanded and displays the Editor Settings:

• Knowledge Base: How does the Performance Center work?

 

1.8: Flip/mirror objects

The models in the Transport and Objects Categories are now flippable along their local coordinates. This increases flexibility for placement of furniture items or adding Cars on the correct lanes:

• Knowledge Base:  How can you Flip or Mirror a model?

 

1.9: User-based login

Lumion 2025 rolls out an easier-to-manage, more secure, and more affordable License type: named-user License. Lumion customers can now log into the product by using the Lumion Account credentials, thus reducing any security risks of communicating the License Key in emails.

1.11: Data structure:

The structure of Lumion files has been re-engineered to future-proof the quality of the stored information. As a consequence, this now allows for faster saving/load times and a small improvement in the file sizes. 

• Very Important: Please note that due to this change, Projects and models saved in version 2025.0 cannot and should not be opened in older versions of Lumion.
• Project merging: both Projects need to be saved in Lumion 2025.0 before merging them.
