关于虚拟阴影贴图mip层级的问题

我在UE5.3.1中导入了我自己制作的树木。但是树叶的阴影在距离较远的时候消失了。我查看了虚拟阴影贴图的mip级别发现阴影消失的距离和不同mip级别的交界线重叠，不确定两者是否相关。是否可以提高vsm的渲染范围以增强阴影的精细程度？应该如何操作？

You can increase the ray tracing distance and / or Lumen trace distance, see

Sorry, this doesn’t work. But thanks. Maybe it has something to do with me enabling nanite?

I found the solution. Check this and the shadow is back.
