Javascript-форум - Three.js как сделать шахмтную доску

Здравствуйте! как разукрасить шахматную доску Three.js
и когда я добавляю анимацию с экрана все пропадает :( :help:

var render = function () {
requestAnimationFrame( render );
if (cube001)
{
Cube001.rotation.x += 0.1;
}		
renderer.render(scene, camera);
};
render();

а, а это полностью :yes:

const cube = new THREE.Mesh( geometry, material );
cube.position.set(i*2,0,j*-2);


if (i==1 && j==1)
