BABYLON.SceneLoader.ImportMesh("", "model/", "weixin.babylon", scene, function (newMeshes, particleSystems, skeletons) { var alpha = 0; scene.registerBeforeRender( function () { for (i = 0; i < 60; i++) { newMeshes[i].position = new BABYLON.Vector3(newMeshes[i].position.x + 10 * Math.sin(alpha), newMeshes[i].position.y + 0, newMeshes[i].position.z + 10 * Math.cos(alpha)); } alpha += 0.01; }); }); here is my code why it show "Cannot read property 'position' of undefined"
