→ May 5 EDIT: May 5nd update: ++Fortnite+Release-24.30-CL-25347382-Windows, still doesn’t fix this issue. This update also includes a problem EPIC is aware of: “- The memory calculation process has been improved to provide a more accurate result. This means that an island reporting a 50k memory result before the update may be reporting more than this now. The memory wasn’t actually increased, the value is being more accurately reported.”
→ EDIT: for those coming back to this thread later: As of April 24th 2023UEFN Version: 5.1.1-25058254+++Fortnite+Release-24.20, it seems that the most important value for this feature, and the one that’s not taken into account, is Loading Range, broken and locked at 25600 units (default). No matter what you type in that value field, it will not change. Did tests in other fresh islands, same behaviour. Also did tests in UE5, and it works as expected. It’s UEFN that’s not reading this value on runtime. You’re not doing anything wrong, again, this is a bug. So things that are “close”, as close is a relative term, will not be offloaded. Please read the whole thread to understand this message.
After enabling streaming, saving and reloading the level, even restarting the editor, the “world partition editor” window is not showing and it’s not present under the “Window” menu like this tutorial suggests.
I’m having the same issue! I can’t seem to get World Partition window, or the loading/unloading assets working. Making it hard to determine how to manage memorhy on my level.
Exactly!
I’m pretty sure I’m doing everything right, and it feels like my project never enables streaming. (world partition)
As a test, I excluded all my assets in the level from HLOD, set the grid and loading range very small, and still, all assets are loaded at once during edit and play sessions. (project memory doesn’t change streaming on or off).
But regardless of my own project, just to make sure I wasn’t making any mistakes, I created a fresh project and followed the tutorial I linked on my original post EXACTLY, and I still can’t see the world partition editor, nor a memory usage change.
Hello @NabuX and @Subject7fx I can confirm that the WP Editor was removed before launch and as such that tutorial is not currently relevant. There are discussions to re-introduce the WP Editor in the future though so stay tuned. Thanks!
@HalcyonKnight96 So does that mean no streaming at all? or just no editor? because streaming doesn’t seem to work either. Can you pelase confirm? so I don’t think I’m doing something wrong. Thanks!
It would be awesome if we could get this system working for us! I have a lot of interior assets I’d love to unload so that my memory usage doesn’t go nuclear!
@HalcyonKnight96 I discovered that these two settings are completely ignored by the Streaming/World Partition function: (did a series of tests with multiple values)
It doesn’t matter what you type there; from 10,000 to 1 to 0, the behaviour doesn’t change. It seems the default values are something like 25,600 for the loading range and 3000 for grid size (which changes depending on which LOD level is loaded or taken into account). With streaming enabled, moving away from objects ~20k units makes them change LOD and/or disappear depending on your settings.
Can you please relay this to the team? it’s an extremely important feature!
Thanks!

Thank you for this thread. I have experience with WP in UE5 but new to UEFN (obvs!). I thought I must be doing something wrong as I couldn’t get assets to unload as I’d expect. This thread reassured me that I’m not going mad.
So, if we want to use a decent number of assets and get them to unload, is the only solution to move them really far apart on the map so that the “default” 3,000 cell size and 20,000 loading range values come into play? Any guidance would be great - thank you.
No problem my friend! Yeah, I did the same thing, I thought I was not getting it, but it just doesn’t work properly.
To answer your question, the only thing you can do right now for this to work is to build “battle royale style” islands, meaning, things really far apart and large maps.
Any “condensed” map, full of indoor assets and props and devices will not work as the Loading Range is fixed on 25600 for now.
Those default values are fine and optimized for big islands, but not for condensed spaces.
@Flak@HalcyonKnight96 is the team aware of this? more and more people are reporting this in multiple Discord communities as well. (I’m talking about Streaming not working as expected, not just the WP Editor missing). It’s quite a blocker to publish large and/or condensed islands. I have already reported it via the bug report form a week ago. Thanks!
@NabuX I’m working right now to aggregate info and get it in front of the team. I’ll keep you updated on this. Sorry for the delay, go lots of different threads going on
@here Wanted to let you all know that the team is actively looking into this issue at this point. I can’t speak to when we’ll have a fix but this is on the radar and currently being worked on
I did test and it did work for a bit. But I updated it as soon as it broke again… I’m not trying to confuse people obviously but I was genuinely surprised it was working for a while - I was changing the loading range and it was updating, so no reason to come at me like that
