Questions

Hi, guys I got a problem when i export editorproject, babylon and texture files from the editor, the babylon file is an empty json and got meshes in the editorproject file.

scene.babylon file:

{
    "autoClear": true,
    "clearColor": [
        0,
        0,
        0,
        1
    ],
    "ambientColor": [
        0,
        0,
        0
    ],
    "gravity": [
        0,
        -9.807,
        0
    ],
    "collisionsEnabled": true,
    "morphTargetManagers": [],
    "lights": [],
    "cameras": [],
    "activeCameraID": "Editor Camera",
    "animations": [],
    "materials": [],
    "multiMaterials": [],
    "skeletons": [],
    "transformNodes": [],
    "geometries": {
        "boxes": [],
        "spheres": [],
        "cylinders": [],
        "toruses": [],
        "grounds": [],
        "planes": [],
        "torusKnots": [],
        "vertexData": []
    },
    "meshes": [],
    "particleSystems": [],
    "sounds": [],
    "shadowGenerators": []
}

scene.editorproject file:
scene.editorproject.zip (65.0 KB)

then load these files by

// Load Scene
    SceneLoader.Load(
      "./scene/",
      "scene.babylon",
      this.engine,
      (scene: Scene) => {
        this.scene = scene;

        // No camera?
        if (!this.scene.activeCamera) {
          this.scene.createDefaultCamera(false, true, true);
        }

        // No light?
        if (!this.scene.lights.length) {
          this.scene.createDefaultLight();
        }

        // Attach camera
        this.scene.activeCamera.attachControl(this.canvas, true);

        // Load extensions
        Tools.LoadFile("./scene/scene.editorproject", (data: string) => {
          // Apply extensions (such as custom code, custom materials etc.)
          Extensions.RoolUrl = "./scene/";
          Extensions.ApplyExtensions(this.scene, JSON.parse(data));

          // Run render loop
          this.engine.runRenderLoop(() => {
            this.scene.render();
          });
        });
      }
    );

But it seems nothing has been rendered.

I saw in editor source code. the class ProjectImporter has a method Import to parse the editorproject content. Is there any package I can install in myself project to load the editorproject file?
