为什么循环中的每个多维数据集都没有投射阴影？

我使用定向光，所有立方体均应投射阴影。但是由于某种原因，它会在5列左右停止。

let dirLight = new THREE.DirectionalLight(0xFFFFFF, 1.5);
dirLight.position.set(300, -300, 400);
dirLight.castShadow = true;
scene.add(dirLight);

dirLight.shadow.mapSize.width = 512;
dirLight.shadow.mapSize.height = 512;
dirLight.shadow.camera.near = 0.5;
dirLight.shadow.camera.far = 1000;

let cubeGeometry = new THREE.BoxGeometry(1, 3, 1);
let cubeMaterial = new THREE.MeshLambertMaterial({
    color: 0xf54242
});

function drawCubes() {
    for (let c = 0; c < 25; c++) {
        for (let r = 0; r < 10; r++) {
            for (let t = 0; t < 2; t++) {
                let cube = new THREE.Mesh(cubeGeometry, …
