Hello!

I am trying to import local .splat/.sog/.ply etc. files as base64 strings, but browsedFile.type reads "" (empty string) and the following error occurs:

Unable to load from data:;base64,...(long base64)...

    at new Promise (<anonymous>)
    at importMeshAsyncCoreAsync (sceneLoader.js:462:18)
    at SceneLoader.ImportMeshAsync (sceneLoader.js:980:22)

when executing

...
import "@babylonjs/loaders/SPLAT";
...
import { SceneLoader } from "@babylonjs/core/Loading/sceneLoader";
...
const meshes = "";
const result = await SceneLoader.ImportMeshAsync(
  meshes,
  base64str, // works fine with URLs i.e. "https://raw.githubusercontent.com/CedricGuillemet/dump/master/Halo_Believe.splat",
  file,
  this.scene);

My app is importing Babylon JS

I tried adding application/json to base64 header, which did not work.

I’ll be grateful for any help.

Thank you!
