UE5 Landscape Jagged Triangular Shadows

UPDATE:

  1. I tested it in a default unreal level and the issue is still there, so I don’t think it’s an Ultra Dynamic Sky issue.
  2. I found a mega-thread (Dynamic shadows artifacts - #71 by Zeblote) and, as far as I can tell, it was never resolved for landscape.
  3. Even with an over-smoothed landscape and high resolution, the issue was still there.
  4. I’m not using Lumen (creates issues with foliage), but it doesn’t fix it anyways.

I’ve attached another screen shot of the issue (in this one the issue is a bit more obvious):

With how old that thread is, I’d be amazed if there isn’t a solution for this issue, especially with the release of UE5.

Again, any help is greatly appreciated!
