There is a bunch of UI changes in the last few engines that just make no sense.
They removed Cell Loading in World Partition instead of making it optional. It appeared in code they already supported swapping out the minimap tab, but instead of adding a new type of tab, someone actually went and re-wrote the entire Cell Loading code into Region Loading instead of just adding it as a separate “module”.
Also the bloated UI overall just isn’t nice to work in anymore. I miss the top bar that actually had text for many buttons instead of these icons. Half my top bar when in the level viewport is just empty now.
Tired of fresh people trying “make their mark” coming in and just reinventing the wheel and just making it worse than it already was, while all the crashes, large landscape, HLODs crashes etc just get ignored.
They seem to only test with “brand new projects” and totally miss out on everything else.
For example, converting a 16k by 16k resolution “pre-world partition” level to WP in (at least) 5.0, actually doesn’t update the WP Cell Size correctly, so you have to export everything and reimport it, and if you don’t do it right it crashes. (Import heightmap first, then turn on Use Material Instance on Landscape, THEN set the material and import the layers.)
