The packaged build of my game does not consistently load landscape collision for all landscape components when streamed in with World Partition. After traveling far enough from the spawn point that new levels start to load in, one will eventually load with no collision and any actors with physics en…

I’m here because I am experiencing the exact same issue. My project was upgraded from UE5.2 → UE5.3. In UE5.2 I was able to cook, package, and test without any issues. I NEVER experienced this before but then when I packaged in UE5.3, the landscape loaded without any collision. If I run the package…

Looks like they fixed this in 5.4 We integrated 27685861 from UE5-main which resolved this issue for us (in 5.3)

That’s very encouraging, thank you!

Not sure if this is somehow related, but I found collision breaks after adding or removing landscape components. The fix is to change the Cell Size in the World Settings (under the World Partition heading). Instead of 12800, try power of 2 values, such as 8192 or 16384 (although other non-power of 2…

Has this problem been solved? What should I do? Thank you very much.

The GitHub commit corresponding to 27685861 is: https://github.com/EpicGames/UnrealEngine/commit/131db749c64a8a5f1b96a6f836a884624429154a#diff-2c7ebdfe53b5fd76c3c2193f3460fb91a9e19b4fa21a3f9d3107c2b67b4dea60

We also started encountering this issue after upgrading to 5.3 and thankfully we found this thread early on. Thanks for documenting this here :pray: We tried to integrate the fix mentioned above but its kinda hard to add without considering “Chaos implicit object ref counted ptr” / TUniquePtr → TRe…

I have an online game and on the client I get the same error. But the server (host) handles the collision correctly. But here is the client for which landscape cells are streamed, without a collision (not all cells, but I didn’t find a pattern). I only know that this problem was fixed in 5.4, but …

Any update on this? I get the landscape working but after a few tweakings in production it started to lost the collision again… not sure what to do to solve the problem
