Summary
Project size stuck at 195% after building HLODs - even after deletion and snapshot reverts
Hey, I have a massive problem with my project size reporting.
Before building HLODs, my project was at 70%. I built them once, and it jumped straight to 195%. The issue is that even after deleting the HLODs, the size is still stuck at 195% and I can’t publish anything.
What I’ve tried so far:
Reverting to older snapshots and re-syncing the project – still 195%.
Deleting the HLOD layers and creating new ones – no change.
Manually deleting the ExternalActors folder from the disk and syncing – still 195%.
I even tried building HLODs again to see what happens – my local folder doubled in size, but the UEFN report stayed frozen at exactly 195%.
It’s like the server-side memory count is completely desynced from my local files. My project folder (ExternalActors) only weighs around 369MB on my disk right now, but the editor keeps screaming about 195%.
I’m making a large Tycoon and thought HLODs would help with optimization, but they just broke my project and there’s no way back.

Project Size
Steps to Reproduce
Start with a project at stable memory levels (around 70%).
Build HLODs for the entire map (World Partition).
Observe the project size jumping drastically to 195%, exceeding the memory limit.
Attempt to delete HLODs using the “Delete HLODs” option in the Build menu.
Revert the project to a previous snapshot from before the HLOD build.
Manually delete the ExternalActors folder and the HLOD Layer from the Content Browser.
Sync the project and refresh the Project Size report.
Observe the issue: The project size remains stuck at 195% despite the local files and snapshots being reverted to a state that previously occupied only 70%.
Rebuild HLODs again and notice that local folder size increases, but the UEFN memory report stays frozen at the same 195% value.
Expected Result
The project size report should accurately reflect the current state of local files and the active snapshot. After deleting HLOD data, removing the HLOD layers, and reverting to a previous “lightweight” snapshot (70%), the memory usage should decrease accordingly. The server-side cache should be purged when those files are no longer present in the project, allowing the memory limit to return to its original state.
Observed Result
The project memory report is stuck at 195% and does not decrease regardless of any local changes. Even after deleting all HLOD data, deleting the ExternalActors folder (reducing local size to ~369MB), and syncing with older snapshots, the UEFN editor continues to report 195% usage.
Furthermore, using the “Clear Derived Data Cache” (Wyczyść pamięć podręczną plików źródłowych) option has no effect on the memory report. The server-side validation seems to be permanently holding onto inflated data from a previous HLOD build, creating a total desync between actual project files and the reported size.
