Expected behavior

Static resources should be packaged correctly and not lost

Actual behavior

If you use electron-forge to package electron, you will lose .obj static files in the packaged file.

Steps to reproduce

I added threejs to electron and then I used electron-forge to package electron. However, .obj files will be lost in the packaged files

    var mtlLoader = new THREE.MTLLoader()
    var objLoader = new THREE.OBJLoader()
    mtlLoader.setPath('static/Map/obj/')
    mtlLoader.load('room1.mtl',function(materials){
        materials.preload();
        objLoader.setMaterials(materials)
    });
    objLoader.setPath('static/Map/obj/')
    objLoader.load('room1.obj',function(object){
        object.traverse(function(child) {
            if(child instanceof THREE.Mesh) {
            child.material.transparent=true;
            child.receiveShadow = true;
            child.castShadow = true;
            child.material.map = texture;
            }
        })
        object.position.set(-6,-6,6)
        object.transparent=true;
        object.opacity=0.5
        scene.add(object);
        renderer.render(scene,camera);
    },undefined,function(error){
        console.log(error)
    });
