1. New feature highlights

1.1: Real-time Ray Traced Preview

Lumion 2024 comes with a new temporal denoiser for Preview and Movie Mode.

1.1.1 NRD for Preview: The Preview is now instantly denoised allowing for a more accurate visual representation when setting the angle of your renders or adjusting the Effect Stack.

Behaviour:

  • NRD is on by default in the Preview and is triggered when adding the Ray Tracing Effect.
  • NRD is also present as a Denoiser in Movie Mode.

1.1.2 NRD for Output: For a final render (Movie/Clip) NRD requires less Samples than OIDN (the original Photo Mode Denoiser) to output a result of similar fidelity.

The temporal aspect of NRD considerably reduces the shimmering effect in Movies/Clips compared to denoisers that do not take previous frames into account.

1.1.3: For background on the technology involved see:

1.2: Raytraced Trees

The Lumion Nature Library has been fully converted to the bindless pipeline, allowing for better shading on the Objects and accurate Reflections.

1.3: Ray Traced Glass and Shadows

1.3.1 The Glass Material is now more physically accurate in Ray Tracing and allows for better control when aiming to achieve a look closer to reality. This is especially visible in more intricate geometry as the shape will correctly reflect and refract light.

1.3.2 In Ray Tracing, the new Glass Material also casts colored Shadows.

Lumion now supports two types of glass: Ray Traced Standard Glass and Fully Ray Traced Glass. Fully Ray Traced Glass can be enabled in the Ray Tracing Effect and will affect all surfaces that have been assigned the Glass Material:

1.4: Ray Traced Subsurface Scattering:

Lumion 2024 also brings ray traced Subsurface Scattering that accurately depicts the natural diffusion of light through surfaces and volumes.

The Slider controls the intensity of the scattering while the Color Picker influences the tint that the object will have once light passes through it.

1.5: Parallax interiors*

A new Content Library Subcategory has been added with 25 Parallax Interiors usable in their day and night variants. With options covering offices, residential spaces, and retail areas, these interiors provide a quick and effective way to elevate the visual impact of architectural renderings.

The Parallax Objects are always facing the camera within the boundary of the object and are resource-efficient, thus improving the scene-building process and saving computational power.

More information:

1.6: Landscape tiling

1.6.1 Landscape Mode: Most textures in the Landscape Mode are now tiled by default using hexagonal mapping to reduce repetitiveness.

1.6.2 Material Mode: Landscape Tiling can also be applied to the Standard Materials in Lumion by enabling the Toggle under the ‘UV Coordinates’ tab.

1.7: Multiple importance sampling (MIS):

This algorithm has been introduced in Lumion 2024 to improve light distribution on objects and rendering efficiency. MIS employs multiple sampling techniques and takes into account the dimension of a light source. As such, it is able to approximate the contribution of light to a pixel and produce a higher accuracy result.

In the example below, two Lights (one measuring 0.1×0.1m and the other one at 1.0×1.0m) have the same Brightness and are placed at the same distance from the subject:

1.10: Batch importing:

Multiple Models can now be imported at once when clicking the ‘Import model button’.

The option to add a prefix is also available and to place the models in a folder within the Lumion-documents of choice:

They will automatically be aligned to the Lumion world origin:

1.11: GLTF Importing

A new format is available in Lumion 2024 for Imported Models: .GLTF/.GLB. The models are generally lighter than other formats and support a PBR workflow.

1.12: Lumion Library content

1.12.1: New Models:

Accurately represent various styles, environments, and contexts in your designs with the new selection of library assets. Choose from 309 new Objects covering the following Categories:

Fine-detail Nature: 100*
18 Plants, 82 Trees
Objects: 9
People and Animals: 45 (15 available in Lumion Standard)

Effects: 130*

1.12.2: New Materials:

      • 26 Brick Materials

1.12.3: Added content can be searched in the Object Library using the ‘L24’ search item:

See also Section 2.5.5 Library Search Tags for the new features (below).

1.13: Camera Controls

panorbit.gif

The option to control the Lumion workspace using consistent controls with the 3D modelling software has been added for the following applications:

      • SketchUp (Pan: SHIFT+MMB, Orbit: MMB)
      • Revit(Pan: MMB, Orbit: SHIFT+MMB)
      • Rhino (Pan: SHIFT+RMB, Orbit: RMB, Look around: CTRL+ALTMMB)
