1. New Feature Highlights
1.1: Volumetric Lights Effect*
Available in Photo, Movie, and Panorama modes.
Omnilights are now included in the Volumetric Lights Effect. This allows for mixing and matching both types of Lights within this Effect.
Lumion 12.3 lets you add a gorgeous glow of light to interiors and exteriors with the improved Volumetric Lights Effect. This subtle lighting detail only takes a click, infusing spaces with warm, inviting lights. When used with fog, an atmospheric real sky, or precipitation, you can instantly create a stunning result.
- Rendering a foggy, moody night
- Visualizing event lighting
- Create a cinematic effect to delight clients
- Show dust, mist, or steam for interior and exterior shots
- Magnify a sense of volume in spaces
1.2: Custom Surface Decals*
In Lumion 12.3, you can now import your own surface Decals to add a touch of your personality and character to the materials.
Simply import a custom image and place it on any surface, and the image will take on all the traits and texture of the material beneath it.
Combine the Custom Decal import feature with other Lumion features, such as Displacement Maps and Weathering, to make your materials even more unique and personalized.
1.3: Custom License plates
With this version, you can also load your own License Plates for vehicles.
- Transport Category: Option to add Custom License Plates in this category.
1.3.1 License Plate Sets can be created, saved, and loaded in your Project containing up to 10 different entries with Front and Rear customization available:
A dedicated panel is also available that allows for scaling the plates to the desired size:
1.3.2 An infobox has been added as a disclaimer regarding the content of the preset License Plates.
1.4: Render multiple Photo Sets
It is now possible to render multiple Photo Sets or a selection of Photos that belong to different Photo Sets. This feature is a workflow boost when a large number of images need to be rendered.
The total number of selected Photos for rendering is displayed under the Photo set label and excluded Photos within a Set will appear greyed out. By default, all Photos are selected.

2.1: Build Mode
Lumion 12.3 now features 32 editable Layers.

- Waxiness and Transparency: the Waxiness and Transparency sliders can now be tweaked at the same time, instead of just one at a time.

- Setting up an urban scene with animated objects and Volumetric Lights.
