Summary

Starting from version 30.00, many warnings occur due to broken references to Niagara assets (Emitter, Dynamic Input, Module, etc.) that Fortnite presumably uses when the project is launched.

Steps to Reproduce

Launch UEFN and open a project created before version 30.00.

Expected Result

The ideal situation is one where the mentioned warnings do not occur.

Observed Result

None

Platform(s)

Windows 11

Have you found a solution to this, as I just had this happen and my map will not launch so I have a 6 month long project dead in the water now.

FORT-760457 incident has been created. Status is ‘Unconfirmed’.

Also looking for a solution. These are the only load errors my map has, no verse build errors or anything. Two days ago I got a moderation warning which is not letting me even launch a session. Some people on reddit and on here seemed to suggest it could be an issue with an asset failing to cook on load and then subsequent UEFN sessions just keep saying that moderation warning. I am thinking this has got to be a big problem as the timing is really synced up with a recent update. How do we restore these Niagara files that are being referenced on project load??

Here were my map load errors:

@el_dud3rlno and @YuyaShiotani
Did you also get the moderation warning for your project as a result of this??

Also looking for a solution to this - happened to me today.

I get load errors with Athena, Environments, ExternalActors and LensFlare.

Do you have water bodies in the map and if so have you tried replacing them?

This indicates that the niagara particle effects are related to a body of water, and my guess is that it may be legacy and not have properly been updated in your project. My best guess at a solution would be manually replacing all water bodies.

the suggested solutions did not work for me :[

10

Also forgot to ask, have you tried repairing the game files thru the launcher?

I am just now experiencing a similar issue (same error) with other ExternalActors after deleting Atlantis Playset Kit meshes from my map. Flipping between recent and older revisions in URC seems to indicate that these warnings are directly problems with the expected/actual project files, as the warning also suggests. Reverting to a recent Snapshot fixes it for me since I’ve made only minor changes, but I know others won’t be so lucky to catch it right away.

My local files are gone as expected, but the editor says the external actors are still 'a dependent package" even though they are no longer needed. I suspect the trick would be to remove the dependencies the project thinks it has on those no longer needed assets. Anyone with deeper knowledge of the dependency process/tooling understand what’s happening here and what we can do to cleanup (somehow corrupted) lingering dependencies in UEFN projects?

I’ve had this problem since 30.30 and it’s still the same in 30.40

It works perfectly in UEFN editor as you can see in the image below, but the system won’t validate when launching a session, which prevents me from play-testing.

Is this still happening after today’s update?

Good news the Flames as in the image I posted are now working in the game I’ve Updated to 31.00 let’s hope that everyone in this post is having the same outcome for their issues. Thanks, Flak for replying

Here is the blueprint Niagara from posting on X

The issue seems to be the Niagara VFXs. Double-check all your Niagara VFXs and ensure the “Effect Type” is set. Some of mine got cleared. Setting all to the default fixed the issue.

Hey I checked all the VFXs that I myself made and they were already on UEFN_DefaultEffectType.

I have load errors that relate to Niagara effects, but only to those that are from the game itself like LensFlare, and I dont know where to access these.

Yes this is now happening to us. This just put a hold on our project and we can’t complete it now. It seems like we can never actually get a game shipped these past 3 months because we always end up having issues.

Quick tip here is that you can create your own custom scalability types, and you can even directly duplicate the standard one so you have a private version that isn’t impacted by updates that reset these scalability systems from default to none if they contain default.

To do this make sure that the default type is selected within a system, and then reopen the effect type selector and click Copy:
image

Go to your project file directory subfolder of choice and paste directly into that directory:
image

Rename your new Default Effect Type file to whatever you’d like and use that in your systems.
These can be further customized within the effects type themselves, and you will need to refer to UE documentation on specifics of what these different settings do, but by leaving it the way it is you have the default that you’re used to and it will be using a file location so won’t be interrupted by these updates in the future (if that is in fact what was going on here.)
