Just adding my voice - it’s frustrating to keep running into the same issues without resolution.
In a quick test, it looks like barriers now disappear at a relatively short distance. And when they come back into render range, the material is visible even if the player is on the ignore list, which shouldn’t happen.
Really hoping this gets fixed soon. I also hope the other issue I reported doesn’t get swept under the rug again. It was marked “needs more info” - even though I provided clear instructions, simple repro code to add all players to the ignore list, and a video showing the bug from multiple perspectives. It was 100% reproducible on Xbox Series X, PlayStation 5, and PC, yet was closed as “unable to reproduce.”
