// Approach 1 (links)
// Once the renderer finds a *MeshFaceMaterial*, it'll process the face material array

var common_material = [ new BitmapUVMaterial( bitmap ) ];

mesh.material = [ new MeshFaceMaterial(), new MeshColorStrokeMaterial( 0xff0000 ) ];
mesh.faces[ 0 ].material = common_material;
mesh.faces[ 1 ].material = common_material;

// Approach 2 (indices)

// This is current solution in alteredq branch 
// ColorStroke material will be automagically applied to the whole mesh // for other FaceColor / Color / BitmapUV materials you need to set decalIndex property

mesh.material = [ new BitmapUVMaterial( bitmap1 ), new BitmapUVMaterial( bitmap2 ), new MeshColorStrokeMaterial( 0xff0000 ), new Mesh BitmapUVMaterial( decal )];

mesh.material[3].decalIndex = 1; // decal will go to head

// torso
mesh.faces[ 0 ].material = 0;
mesh.faces[ 1 ].material = 0;
mesh.faces[ 2 ].material = 0;

// head
mesh.faces[ 3 ].material = 1;
mesh.faces[ 4 ].material = 1;
mesh.faces[ 5 ].material = 1;
