Can't load Gaussian Splat into React project

Hello, I am a first time user and running into an issue while trying to load a Gaussian splat into my scene in a React project.

To reproduce (also I provide a StackBlitz)

  1. I just cloned the latest Vite + React + Typescript starter repo
  2. added the boilerplate / starter-code from this guide: Babylon.js docs
  3. added the mesh loader line from this example: https://playground.babylonjs.com/#M05L0C#1
  4. The mesh is not visible in the scene, and I get the following console error:

    CleanShot 2025-02-28 at 11.52.52@2x2956Ă—326 97.2 KB

Full repro here: Vitejs - Vite (forked) - StackBlitz

Has anyone got gaussian splatting working with React, or know what may be causing this error? Thank you

Babylon.js loaders are needed to load splats and it’s missing from package.json.

Thanks, I tried adding the loaders in the Stackblitz, however I get the same error.

I still get RuntimeError: Unable to load from https://raw.githubusercontent.com/CedricGuillemet/dump/master/racoonfamily.spz: importMesh of undefined from undefined version: undefined, exporter version: undefinedimportMesh has failed JSON parse

(package.json: Vitejs - Vite (forked) - StackBlitz)

You should register the builtin loaders before load the model (preferably in App.tsx):

import { registerBuiltInLoaders } from "@babylonjs/loaders/dynamic";
...
registerBuiltInLoaders();

“This will register all supported loaders, but internally uses dynamic imports to only download/load a specific importer (e.g. glTF, splat, etc.) when a model of that type is first loaded.” Taken from here:

As side note, keep update to the same version both @babylonjs/core and @babylonjs/loaders otherwise you will get compilation errors if you install for the first time the dependencies declared in the existing package-lock.json.

import { registerBuiltInLoaders } from “@babylonjs/loaders/dynamic”;
…
registerBuiltInLoaders();

That fixed it for me, thank you! And good to know about the package versions.
