Luma AI has started April with a bang, announcing a integration of NeRFs in Unreal Engine 5. This continues to open the floodgates for professional uses and further developments into the gaming and VFX world. This groundbreaking product feature is set to revolutionize the way creators, developers, and gamers interact with virtual environments, offering unparalleled photo-realistic rendering capabilities through Luma Fields.

Previously, we have seen integrations to NeRFstudio with Volinga AI and Instant NGP with Velox. Luma had previously been quiet on any plans to expand into Unreal Engine, but the move, while inevitable— was unexpected so soon.

Luma AI in Unreal Engine 5 Plugin

Getting Started with Luma AI in Unreal Engine

Download the plugin here and it is compatible with Windows.

Luma also suggests downloading their cinematic and film starter pack.

  1. Download the sample project and extract it somewhere

  2. Open it in Unreal Engine 5 by double-clicking the .uproject file

    • (This might initially take a while for Unreal to compile shaders if you have never opened Unreal Engine before or didn't compile some of Unreal's shaders before.)

  3. Download a Luma Field file from one of your captures

  4. Drag the downloaded file into the Content Browser in the Unreal Editor

  5. After a couple of seconds, Blueprints will be generated for your NeRF captures, which you can simply drag in and use inside Unreal Engine!

    • Depending on your system, it might take a couple of seconds to compile all the Blueprints – you can already drag them into the scene while they are compiling and they will start to render once the compilation is done.

  6. There are multiple Blueprints generated for each Luma Field

    • Baked: These Blueprints contain the lighting as you captured them, so they will look as close to your capture as possible. They are not affected by shadows, or lighting, but can still be composited with other Luma Fields and Unreal Objects.

    • Dynamic: These Blueprints are affected by Unreal's lighting and shadows.

    • Cropped: These Blueprints contain an automatically cropped version of the center object of your capture, if one exists.

    • With Environment: These Blueprints additionally render a fitting sky environment for each capture for any region that was unseen during capture.

If you are planning on using the plugin in to view a Luma Field in VR, Luma AI recommends:

we recommend using the DLSS plugin on NVidia GPUs with a ScreenPercentage of 50% to ensure smooth rendering and prevent motion sickness.

Luma AI

NeRFs, are a cutting-edge technology that harnesses the power of artificial intelligence and deep learning, have gained immense popularity for their ability to generate incredibly lifelike scenes. The technology works by capturing a scene's 3D structure and appearance from a collection of 2D images, rendering the scene with stunning accuracy and detail. With Luma AI's latest innovation, users can now access NeRFs directly within Unreal Engine, opening up new creative possibilities and transforming the way digital content is developed and consumed.

The introduction of NeRFs in Unreal Engine is expected to have a significant impact on industries such as gaming, architecture, film, and virtual reality, where high-quality 3D rendering is crucial for delivering immersive and realistic experiences. By offering a more efficient and visually impressive method of generating 3D content, Luma AI's latest feature has the potential to redefine industry standards and streamline the creative process for professionals in these fields.

Luma AI's NeRFs-Unreal Engine integration has already garnered considerable interest from the global tech community, with many eager to explore the new horizons it will open up. As developers and creators continue to push the boundaries of what is possible in the digital world, the incorporation of NeRFs in Unreal Engine is poised to become a major milestone in the evolution of 3D rendering technology. We are entering a new, exciting chapter of NeRF and I am excited to see what is created from it.

Shrinking 3DGS File Size

Gaussian Splatting has quickly become one of the most exciting research topics in Radiance Fields, thanks to its fast training, real time rendering rates, and easy to create pipeline. The one critique that emerged was the resulting file size from captures, often venturing into the high hundreds of megabytes and up.

A short 170 year history of Neural Radiance Fields (NeRF), Holograms, and Light Fields

Lightfield and hologram capture started with a big theoretical idea 115 years ago and we have struggled to make them viable ever since. Neural Radiance fields aka NeRF along with gaming computers now for the first time provide a promising easy and low cost way for everybody to capture and display lightfields.
