mrdoob/three.js — Issue #1258: How to change the way shading looks on cubes in Three.js?

I'm creating a little game using Three.js and everything is going well apart from shome shading issues with cubes. I'm basically building a game level by just dropping textured cubes down to form a maze. The problem is that when the cubes are next to one another, each one is shaded in such a way that it looks as if it's a separate entity and not part of a larger wall.

Here is an example, notice the illusion of a single wall is lost:

Is there a different shading technique i should use or is there a nice property to be set somewhere to change this shading behavior?

This is my cube model:

```javascript
{

"metadata" :
{
"formatVersion" : 3,
"generatedBy" : "Blender 2.60 Exporter",
"vertices" : 8,
"faces" : 6,
"normals" : 8,
"colors" : 0,
"uvs" : 4,
"materials" : 1,
"morphTargets" : 0
},

"scale" : 1.000000,
"materials": [{
"DbgColor" : 15658734,
"DbgIndex" : 0,
"DbgName" : "WallCube",
"colorAmbient" : [1.0, 1.0, 1.0],
"colorDiffuse" : [1.0, 1.0, 1.0],
"colorSpecular" : [0.15, 0.15, 0.15],
"mapDiffuse" : "../../textures/walls/stone/stone.png",
"mapDiffuseWrap" : ["repeat", "repeat"],
"mapNormal" : "../../textures/walls/stone/stone_normal.png",
"mapNormalFactor" : 1.0,
"shading" : "Lambert",
"specularCoef" : 25,
"transparency" : 1.0,
"vertexColors" : false
}],

"vertices": [50.000000,-50.000000,-50.000000,50.000000,-50.000000,50.000000,-50.000000,-50.000000,50.000000,-50.000000,-50.000000,-50.000000,50.000000,50.000000,-50.000000,50.000000,50.000000,50.0000050,-50.000000,50.000000,50.000000,-50.000000,50.000000,-50.000000],

"morphTargets": [],

"normals": [1.000000,-1.000000,-1.000000,1.000000,-1.000000,1.000000,-1.000000,-1.000000,1.000000,-1.000000,-1.000000,-1.000000,1.000000,1.000000,-1.000000,-1.000000,1.000000,-1.000000,-1.000000,1.000000,1.000000,1.000000,1.000000,1.000000],

"colors": [],

"uvs": [[0.000000,1.000000,1.000000,1.000000,1.000000,0.000000,0.000000,0.000000]],

"faces": [43,0,1,2,3,0,0,1,2,3,0,1,2,3,43,4,7,6,5,0,0,1,2,3,4,5,6,7,43,0,4,5,1,0,1,2,3,0,0,4,7,1,43,1,5,6,2,0,1,2,3,0,1,7,6,2,43,2,6,7,3,0,1,2,3,0,2,6,5,3,43,4,0,3,7,0,3,0,1,2,4,0,3,5]

}
```
and this is how i load it:
```javascript
JSONLoader = new THREE.JSONLoader();

Light = new THREE.PointLight(0xFFFFFF);
Light.position = {x:0, y:75, z:350};

Meshes = [];
JSONLoader.load("../assets/models/cube.js", function(Geometry)
{
for (var MeshIndex = 0; MeshIndex <= 5; MeshIndex++)
{
Meshes[MeshIndex] = new THREE.Mesh(Geometry, new THREE.MeshFaceMaterial());
Meshes[MeshIndex].position.x = MeshIndex * 100;
Scene.add(Meshes[MeshIndex]);
}
});

Scene.add(Light);
```
Any ideas how to make the cubes look like a continuous wall?
