File Formats

Which formats should I use for meshes versus Gaussian splats?

Choose your pipeline before scanning:

  • Meshes: export .glb or .glTF if you need editable geometry, UVs, and animation.
  • Gaussian splats: export .ply, .spz, or .splat when capturing real-world scenes as point clouds.

Switching later is difficult, so pick the correct format family right from the start of your capture.

Which capture apps do you recommend for creating splats or meshes?

Several mobile and desktop tools export directly to supported formats:

  • Scaniverse (iOS/Android) → .obj, .ply, .fbx
  • Polycam (LiDAR + photogrammetry) → .obj, .ply, .fbx, .stl
  • RealityScan (Epic Games) → .obj, .glb via Sketchfab
  • Postshot (Windows) → .ply splats from short videos

Pick the exporter that matches the format you plan to upload to Arrival.Space.

How can I change the format of my splats (e.g., from .ply to .spz)?

To change the format of your splats, you’ll need to use a file conversion tool or software that supports converting between formats like .ply and .spz. We currently don’t support direct conversion within the platform.

Which format is supported for the 360° option?

The 360° option supports uploaded videos only. If you're a Pro customers, you can also upload 360° skyboxes to enhance your experience.

Which video formats are supported?

We support various video formats, but it’s recommended to upload files in commonly supported formats like .mp4. If you're unsure about compatibility, we suggest converting your video to an accepted format before uploading.

I've created a scan with Scaniverse and got an .obj file - how can I use it inside Arrival.Space?

In Scaniverse you can change the format when creating/exporting. Select .ply format and then you can upload it directly to Arrival.Space as e.g. Main Asset.

How can I clean or convert my files before uploading?

Use desktop editors to prep your assets:

  • Blender — decimate meshes, bake textures, or convert .obj/.fbx to .glb.
  • SuperSplat — convert point clouds into smoother splat renderings.
  • MeshLab — clean scans, remove noise, and export lighter .ply files.

Optimizing before upload keeps file sizes manageable and speeds up processing inside Arrival.Space.
