Export Three json does not export material properties well

[ArnaudAndre]

Hi set and fbx in Clara and looks pretty good with transparency and opacity, (is a bottle) but when I export to three JSON and load it with

 var loader = new THREE.ObjectLoader();
            loader.load($('#model').val(),function ( model ) {
  });

the bottle don't who the transparency or the opacity, in fact it looks with opacity 1 in my material Mesh. I guess the material properties aren't exported pretty well.

The many of the advanced material properties that Clara uses in its editor are not supported by the JSON export process. We are adding glTF export that will replace the JSON exporter currently used. This will help.
