3D Gaussian Splat (3DGS) is an innovative technique for reconstructing and rendering real world objects and environments. 3DGS provides the most realistic visualizations of reality data from photos and/or laser scans. All applications that generate 3DGS data can export to the PLY format. For a full list of the most common tools used to create 3DGS PLY files (both free and commercial), refer to the bottom of this help article.
Nira currently supports uncompressed PLY. If your 3DGS file is in a different format (e.g., compressed .ply, .spz, .splat, .ksplat, .glb, .glTF, or USD), please use the free SuperSplat Editor to convert and export it as an uncompressed PLY file.
Export from SuperSplat:
Modify your SH Bands setting. Reducing this value will significantly decrease file size and improve rendering and loading performance in Nira, though it may impact the visual quality of reflective surfaces.
We’ll continue to update this help article with a more comprehensive list of tools and techniques as the 3DGS ecosystem evolves. Follow this page to stay informed about future updates.
Settings:
Adjust the Splat Size setting to visualize the points that make up each 3DGS.
Modify the Max Spherical Harmonic Degree setting to reveal the reflective details of each 3DGS.
Supported Plans
3DGS is supported on all current plans (Individual, Professional, and Enterprise), however, 3DGS is not supported on legacy plans such as Core or Business (Learn more).
Multiple splats
When uploading multiple .ply 3DGS files, Nira will automatically merge them into a single file during upload. It's not possible to toggle individual 3DGS files on or off, or to add additional 3DGS files to an existing asset that already contains 3DGS data.
