[BUG]: castShadow/receiveShadow 无效

[OriIIusion]

Bug描述

官方阴影说明codepen示例中，灯光的castShadow打开，方块的castShadow关闭，地面的receiveShadow也关闭，阴影仍然存在。

Bug复现流程

通过以下步骤产生bug:

1. 打开官方文档平行光阴影的codepen页面
2. 将灯光的castShadow 设置为false，阴影消失，这是对的。
3. 将灯光的castShadow 设置为true,方块的castShadow设置为false，地面的receiveShadow也设置为false，阴影仍然存在。

期待的结果

场景中会有一部分物体希望显示阴影 另一部分不想展示阴影。不想展示阴影的那些物体怎么设置？

测试引擎版本:

0.6.9
