# Gaussian splat reconstruction in OTOY Studio

OTOY's own splat training nodes. Turn a set of photos or a video into a Gaussian splat or a clean mesh, with a choice of methods for different kinds of scenes.

In OTOY Studio, Gaussian splat reconstruction (OTOY) costs **10 to 29 credits (€0.10 to €0.29)** per run at list price, depending on the settings you pick. It's included on every plan, Free included, and paid plans take 10% to 25% off every run.

## Variants

| Variant | Takes | Produces | Credits per run |
|---|---|---|---|
| Gaussian Splat | Prompt plus image or video | Gaussian splat, 3D model or video | 10 |
| InstantSplat | Prompt plus image or video | Gaussian splat, 3D model or video | 22 |
| 2D Gaussian Splat | Prompt plus image or video | 3D model or video | 25 |
| Neural Harmonic Textures | Prompt plus image or video | Gaussian splat or video | 29 |

## Gaussian Splat

Standard 3D Gaussian Splatting (COLMAP), the general-purpose choice for scenes, walkthroughs, and product capture. Needs 10-500 overlapping photos, or a video. Outputs a viewable PLY splat. ~15-25 min.

Credits per run: 10 credits (€0.10).

## InstantSplat

MASt3R neural reconstruction (no COLMAP) for sparse or tricky scenes where feature matching struggles. 3-35 images (all the same resolution), or a video. Outputs a viewable splat. ~10-20 min.

Credits per run: 22 credits (€0.22).

## 2D Gaussian Splat

Surface-aligned splatting for geometry, extracts a clean triangle mesh (TSDF) and per-view depth maps. Needs 10-500 overlapping photos, or a video. Outputs a mesh + depth, not an inline splat. ~15-25 min.

Credits per run: 25 credits (€0.25).

## Neural Harmonic Textures

Highest-fidelity splatting, a per-gaussian neural decoder captures reflections, glass, and other view-dependent materials that standard SH can't. Needs 10-500 overlapping photos, or a video. ~15-25 min.

Credits per run: 29 credits (€0.29).

## Using Gaussian splat reconstruction in OTOY Studio

1. Open https://app.otoy.studio and create or open a workflow.
2. Add a Gaussian Splat node from the 3d and gaussian splats menu.
3. Connect your inputs (a prompt, plus image or video) and pick your settings. The node shows the credit cost before you run it.
4. Run it. The output lands in your asset library and can feed the next node, for example an upscaler or an Octane render.
