Ray Traced Distance Field Shadows

Hi guys, I am trying to tune Ray Traced Distance Field Shadows to be casted at 600km with FOV ~5
So far my main questions are:

  • Is it actually possible? What is the maximum disitance? (by now I have only figured out how to render shadows at 10 km, but further increasing Distance Field Shadow Distance or Distane Field Trace distance doesn’t help)
  • Why do shadows move when I zoom in/out? They seem to loop appearing and disappearing as I scroll further. Feels like it changes view frustum or something…

The view from 10 km (on the right) and 11 km (on the left), where shadow are no longer visible

我也遇到了这个问题,看起来似乎是距离场阴影的屏幕空间剔除问题,但是找不到解决方法,在使用CSM时他们是正常的
