Problem with water post process effect in many lanscapeStreamingProxy

Hello
I have an error starting underwater postprocess for Ocean in some LandscapeStreamingProxy on a level with World Partition.

  • In about 1/2 of the ocean the underwater effect is visible, in the rest it is not
  • the effect does not appear in neighboring LandscapeStreamingProxy
  • approximately it concerns LandscapeRegion_0_0 and andscapeRegion_1_0, but not exactly
  • I do not know if it is a bug or a matter of some settings. On my other test Open World level everything is correct

The last thing I would like to do is replace Water Body Ocean with a new one, because I have a complicated coastline and it is laborious (I also do not know if it will bring the effect).

I have had the level for many months, I think the error appeared during some update. I am currently working on version 5.5.4

I removed all Landscape Region actors, it not helps.

The ocean was not where it was visible and it would seem - solved.
