Installation

Place Export3JS folder in your Unity project assets folder, and corresponding menu item must appear in Unity's menu panel.

Usage

In the exportation window select options you need and choose the folder for output file.

In Tags submenu you can choose tags you wanted to trace. Then exporter will also create {SceneName}Tags.json file in the output folder with following format:

tags: {
 ExampleTag: [
  "THREE Object UUID"
 ],
 ...
}

In your Three.JS code then read this file, find objects by their uuids and do whatever you need.

If scene contains spotlights, exporter will create another .json file in output directory, named {SceneName}LightsConfig.json. Three.JS spotlights doesn't use their rotation and need a target object to be able to shine in specific direction. The format of this helper file is following:

spotlights: {
 "Light Object UUID": [
  x,
  y,
  z
 ],
 ...
}

For each spotlight in scene there are coordinates of abstract target object, that you need to create manually in your Three.JS code.

After job is done, load JSON file with ObjectLoader:

var loader = new THREE.ObjectLoader();
loader.load('assets/output.json',
  function onLoad(object) {
    scene.add(object);
    // Or even like this, because exporter exports into ready for use THREE.Scene
    // scene = object;
    console.log('Scene has loaded, yeah!');
  }
);
