[lslzl3000]

Describe the bug

If there are point/spot lights and dir lights in one scene, only dir light shadow is visible

To Reproduce

Steps to reproduce the behavior:

1. add a dir light with castShadow, it works fine
2. then add a point/spot light, can't see its shadow
3. try to switch the debug option, point shadow only works when there is no dir shadow

there should be two shadows
