You need to set texture coordinates to meshes to use textures with them, there is an example here:

As you see at the very beginning, the polygons are attached to a shape, the appearance is attached to the same shape. These polygons have texture coordinates, that's why it works. Have you tried to use build-in loaders to load existing 3D models with their texture coordinates?
