1、同一场景中，灯光数量若超过4个，必定有一个灯光发生报错情况，解决方法是只能将所有灯光移动性改为“可移动”吗？
2、最近接触到持久关卡，将场景灯光做了分层，输出图片出现"Sub-level is set to blueprint streaming and will not be visible during a render unless a Sequencer Visibility Track controls its visibility or you have written other code to handle loading it."
我想是因为没有将这个灯光层加入序列 渲染，所以输出的结果是全黑的，目前未接触蓝图，不清楚如何才能获得正确结果。
如有错误，请指正，谢谢
