I am trying to load a JSON file that I exported from blender. There are two meshes and two materials in the file. This is the code that I use to load the JSON.

var self = this;
var mushroomLoader = new THREE.JSONLoader();
    mushroomLoader.load('/js/Mushroom.js', function(mushroomGeometry, mushroomMaterial) {
    var shrooms = new THREE.Object3D();
    var mushroomCount = 10;
    var radius = 30;
        for(var i = 0; i < mushroomCount; i++) {
        var m = new THREE.Object3D();
    m.add(new THREE.Mesh(mushroomGeometry, mushroomMaterial[0]));
    m.add(new THREE.Mesh(mushroomGeometry, mushroomMaterial[1]));
        m.position.x = radius * Math.cos(Math.PI * 2 * i / mushroomCount);
        m.position.z = radius * Math.sin(Math.PI * 2 * i / mushroomCount);
    shrooms.add(m);
    }
    self.scene.add(shrooms);
}, 'images/textures');

The mushroom is separated into two meshes, the top and the trunk. I am using MeshPhongMaterial. The texture that is flashing/disappearing is on the top. The weird thing is that some of them display correctly.

    You appear to be adding two child meshes with identical geometry to each object, with the child meshes both in the same location. If so, that will cause z-fighting and flickering. – WestLangley Jul 06 '13 at 14:06

You were right @WestLangley! I changed my code from this

var m = new THREE.Object3D();
m.add(new THREE.Mesh(mushroomGeometry, mushroomMaterial[0]));
m.add(new THREE.Mesh(mushroomGeometry, mushroomMaterial[1]));

to

var m = new THREE.Mesh(mushroomGeometry, new THREE.MeshFaceMaterial(mushroomMaterial));

and I am not having anymore issues. It seems so simple in retrospect. I thought it was weird that THREE.SceneUtils.createMultiMaterialObject uses the same geometry for both meshes.
