1
Use a 3DGS pipeline that supports SPZ4 export (e.g. Nerfstudio, Luma AI, or compatible tools). The file extension is .spz4.

SPZ4 uses a new header structure. Viewers built for SPZ v2/v3 (pre-2026) will error. This viewer uses Babylon.js with native SPZ4 support.
Convert between SPZ4, SPZ and PLY entirely in your browser — no upload, no server.
