## FAQ

### What's the difference between SPZ and PLY formats?

SPZ is Marble's native splat format optimized for file size, while PLY is a
uncompressed format compatible with more Gaussian splat software packages.

### Why are my splats / meshes upside-down when I export them to other software?

Default world labs worlds are in OpenCV coordinate system (+x left, +y down, +z forward).
Many DCC software are in the OpenGL coordinate system (+x left, -y down, -z forward).
To correct for it, perform an OpenCV-to-OpenGL transformation by scaling the Y and Z
axes by -1 (keeping X unchanged).
