New in SuperSplat: Software Attribution, Collision Generation and GPU-Powered Histogram

Last month we shipped Downloadable Splats, Licenses and Social Links — giving creators more control over how their work is shared and credited. Today we're back with three more upgrades that span the whole SuperSplat experience: from how splats are tagged and discovered, to how they're made walkable, to how they're edited.

🛠️ Software Attribution​

No two splat creators work quite the same way — our community draws on an ever-growing ecosystem of capture rigs, reconstruction pipelines and post-processing tools, each leaving its own fingerprint on the final scene. With Software Attribution, you can now tag your splats with the tools you used to make them, so other creators can learn from your workflow and discover the tools shaping the field.

Open the Manage page for any of your splats and head to the new Software Used card. Search the curated catalog — including Brush, Postshot, LichtFeld Studio, RealityScan, KIRI Engine, COLMAP, Luma, Nerfstudio, Scaniverse, Polycam, Agisoft Metashape and more — and add up to six entries. Drag to reorder them. Don't see your favorite tool? Search for it and the picker will offer a quick way to request it — or just give us a shout on Discord.

Once tagged, the software you used appears as a row of logo chips on your scene page. Click any chip to browse other splats made with the same tool — a great way to find new creators, learn techniques and see how each tool shines in different hands.

🧱 Collision Generation​

Last month we launched Walk Mode, which relies on voxel collision data generated by SplatTransform 2.0. Until now, producing that collision data meant running SplatTransform locally on your splat. Today we've wired the SplatTransform 2.0 pipeline directly into the SuperSplat Studio backend — so you can generate collision for any of your splats with a single click, no command line required.

Open your splat in SuperSplat Studio, head to the Assets panel and hit Generate in the Collision section. Three simple presets — Indoor, Outdoor and Object — tune the generation for the kind of scene you have. The algorithm also needs a seed position to know where the navigable space begins, and Studio takes that automatically from your initial camera position — so as long as you're framing the scene from inside the walkable area, you're good to go.

Browse the walkable gallery to see what the community has been building.

📊 GPU-Powered Histogram​

The SuperSplat Editor's Data Panel has had a major upgrade. The histogram is now GPU-driven, computing per-property statistics across millions of Gaussians in milliseconds — even on modest hardware.

Even better, you can now select splats by dragging a range directly on the histogram. Drag to set a selection, hold Shift to add to the current selection or Ctrl to subtract from it. Locked and deleted splats are protected automatically.

The list of properties you can analyze and select against has grown too. Slice your data by:

  • Position — world coordinates and distance from the origin
  • Depth — distance from the active camera
  • Color — R / G / B and H / S / V (with a fix for HDR scenes pushing values out of range)
  • Geometry — scale, volume and surface area
  • Orientation — quaternion components
  • Raw values — f_dc and per-coefficient f_rest spherical harmonics

New Visible Splats Only, Log Scale and All Properties toggles let you focus the histogram on exactly what you care about.

This makes editing huge scenes dramatically faster — isolate the splats you care about with a single drag instead of nudging sliders.

💚 Free and Open Source​

SuperSplat, SplatTransform and the PlayCanvas Engine are all free and open source under the MIT license. We believe the best tools for 3D on the web should be accessible to everyone.

If you're building a splat-based application, we'd love for you to build it on PlayCanvas. Check out our repos on GitHub:

👂 We Want to Hear from You​

What do you think of the new features? What would you like to see next? Come and join us on the PlayCanvas Discord — it's where the world's best splat creators hang out and we'd love to have you there.

See you in there!
