Babylon.js: When i load stl file, it shows importScene of undefined from undefined version

[flzyup]

Bugs

• Bug repro on playground:

BABYLON.SceneLoader.Append('/assets/stl/', 'arm.stl', scene, function(scene) {

});

• Expected result: expect to load stl
• Current result: but it failed with exception as following:
  BJS - [02:26:40]: Unable to load from /assets/stl/arm.stl: importScene of undefined from undefined version: undefined, exporter version: undefinedimportScene has failed JSON parse

Hello did you make sure to reference the stl loader first?

@deltakosh yeah, i used angular js, and imported as following:

import * as BABYLON from 'babylonjs';
import * as BABYLON_LOADER from 'babylonjs-loaders';

export class TestComponent {
     testMethod() {
      // ... init scene
      BABYLON.SceneLoader.Append('/assets/stl/', 'arm.stl', scene, function(scene) {

    });
     }
}

@deltakosh I fixed by modify the import: import 'babylonjs-loaders'; Thanks

I tried with that import but I wasn't still able to load the .obj. It seems that webpack is doing something fancy behind. I solved with this quick workaround:

import { Engine, Scene, ArcRotateCamera, HemisphericLight, Vector3, Mesh, MeshBuilder, SceneLoader } from 'babylonjs';
import {OBJFileLoader} from 'babylonjs-loaders';


SceneLoader.RegisterPlugin(new OBJFileLoader())
