A couple of months after the release of KIRI Engine V3.12, the platform is once again setting a new standard with the release of V3.13. This latest update introduces High-Fidelity 3D Gaussian Splatting (3DGS), which looks like it’s pulling from some of the latest research methods.
The flagship feature of this release is the high-fidelity 3DGS training method. This innovation pushes rendering quality a bit higher, ensuring that 3D models created with KIRI Engine look more detailed and lifelike than ever before.
Performance improvements are another highlight of V3.13. The update cuts 3DGS training time in half, allowing creators to complete their projects more quickly without compromising quality. For me, it takes about 10 minutes from original upload to interactive 3D. This definitely makes it interesting for cloud-based upload reconstruction services, since Luma’s New Upload functionality has been fluctuating on and off for the past few months.
Additionally, the file sizes for 3DGS outputs have been reduced by 50%, making storage and sharing far more efficient. This is also of course building off previous compression improvements and now drops capture sizes to often below 100MB. These new compressed files still include Spherical Harmonic support, which powers that lifelike look. It looks like a big way they’re accomplishing this is reducing the splat count per capture, which is an awesome advancement to see. It also seems that featureless objects, such as walls and smaller details like snow and grass, are also getting a boost in reconstruction ability.
Flexibility and usability have also been significantly improved. All scan modes now support both photo and video inputs, providing users with greater creative freedom in how they capture their radiance fields. Another thoughtful addition is the locked white balance feature during scanning, which ensures consistent color fidelity across all scans. I still would advocate for capturing using the Black Magic Camera.
For those who rely on 3DGS to Mesh, V3.13 brings important upgrades. Mesh texture quality has also been slightly improved, giving models a more polished and refined appearance.
Other quality-of-life updates include the introduction of the "Save to Local" toggle, which replaces the previous "Store Raw Data" option. This new feature allows users to save their photosets and videos directly to their phones, improving accessibility and convenience. Additionally, Spanish language support has been added, expanding the platform's accessibility to a broader global audience.
Finally, V3.13 improves 3D model scaling, ensuring that models maintain generally accurate proportions and dimensions across different workflows.
With this update, KIRI Engine continues to release updates to its 3D Gaussian Splatting implementation. By combining improvements in rendering quality with practical enhancements to speed, efficiency, and usability, the platform ensures that creators can push the boundaries of their work without being held back by technical limitations. There’s been no word yet on when they will be open sourcing their 3DGS to Mesh pipeline, but hopefully it will be sooner than later.
