Still a ton of Niagara warnings in 31.20 for assets that are packaged with UEFN. Experimenting with the volcano template island, a day sequence device, and a few item spawners, and I’m already encountering these:

hi,
This is the same problem as
UEFN 31.20 New Feature Template Day Sequencer Project Crashes UEFN
Looks like the volcano template has the same problem all in the known errors

25

Has anyone found a solution to this?
After the new update I get these errors on my map and I’ve been trying to figure out the problem for two days.

Yeah I am having this aswell since the og 2 update. 4 months down the drain if this don’t get solved…

edit: I have now tried to test publish it even tho the warnings are still there. It seemed to be all right and went smoothly. So it seems like the warnings won’t stop me from publishing at least when i am done. So that’s nice.

I’m having the same errors and also errors like this:
LoadErrors: Warning: While trying to load package /Game/Effects/Fort_Effects/World/NewChests/NS_Chest_Knight
my chests were first disappearing out of nowhere, which i fixed by verifying uefn’s files, and now my chests only drop two different weapons (this is the case for the chest from chest and ammo gallery). And in-game it only drops resources and not even weapons. This is since the chapter 2 update. It’s ruining my player base and map.

29

This is also one of the errors i’m getting maybe causing my chests not to drop anything

LogDirectoryWatcher: Warning: Failed to begin reading directory changes for C:/Program Files/Epic Games/Fortnite/FortniteGame/Plugins/GameFeatures/Creative/Devices/CRD_ChestAmmoGallery/Content/Localization. Error: Het systeem kan het opgegeven bestand niet vinden.* (0x00000002)
(system can’t find the file*)

I’m having this exact issue as well. However, I don’t even have any Niagara systems in may game yet these errors are popping up. I was playtesting my game fine but then it crashed and I’m getting this error when attempting to relaunch the session.

31

Don’t have any Niagara either, and this happens all time now that these errors popup, even before launching a project from UEFN. When you startup UEFN from Epic Launcher, you get 3 errors that show up.

32

same here, but in my case i cannot build HLOD and it will failed… and heres one the error log:

While trying to load package /Game/Effects/Niagara/Systems/NS_PlayerSwimming/NS_Player_In_Water_HandSplash_Sprint, a dependent package /Game/Effects/Niagara/Modules/Water/WaterBodyLocation was not available. Additional explanatory information follows:

I am having the same issue, I reached out to support to see for a potential guide on fixing this. I looked for the missing files manually, I verified file integrity , I am not sure if this is the reason I am unable to publish my map.

this is my first time to build HLOD since some of my maps are so heavy with tons of props in the map. so i need to optimized them to avoid laggy. hope we will get the solution soon

I have had same issue for over a month now. UEFN loads with FPackages Error of missing files 48 of them even on a verify, reinstall and installing on a completely different machine you still get 48 errors. What I don’t understand is i find this error since June and not one official post that I seen has made a comment. This has made my maps all have errors and can’t be used. Very disappointed that there has been no signs of possible solutions or anything their is an issue but there is I have two PC with this issue and one was a new install just yesterday.
