i am also having this issue, its not a performance thing either it happens every single tim eim doing terrain

yeah, we can’t do much bout it

Thank you for reporting this crash issue!

We tried to reproduce it but without much success. Can you maybe provide some more information about when this is happening? Does it happen any time you use a Landscape Sculpt tool or only for specific tools? Is it easily reproducible every time or does it sometimes happen and other times it works fine?

Any further information would be appreciated.

well in my case I was just editing terrain and then the editor just freezes and then it crashes


here is a video how it is happening

I have the same problem as you, editing a terrain and crashing a few seconds later. Everything except that works very good, only it happens in “Landscape Mode”. I hope we can find a solution for our problem!

Follow-up question: The Landscape actor you are sculpting, was it created from scratch in UEFN, imported from an existing template, or was it copied from UE5 or created in some other way?

It doesn’t matter, it’s any landscape. In my case for example I created “Basic” template project > Landscape tool > (basic terrain settings, 63x63) hit create > Now I have landscape and I edit that terrain, sculpting, smoothing, noise and so on > then randomly crashes with the same logs like the author of this thread, sometimes it crashes after 15 seconds and sometimes (maybe twice) I managed to edit for 10 minutes max… Another example, after first time installing UEFN I tried Tilted Towers Template project and in there I was editing terrain too and was experiencing crashes anyways. I reinstalled UEFN once or I deleted local files, nothing helped.

well after I got into landscape mode I just made a landscape with no height map
with the default terrain material

do you have high end pc or low end pc?

I hope that we can fix our problem because it’s the same problem for all of us (literally the same case). I can provide any information to get it fixed.

Decent pc for sure, it’s good for it, I can tell you that in regular Unreal Editor 5 everything works fine, I was editing terrain in UE5 earlier and no similar crash have happened, I’ve been working in UE5 for a full month, Ive had crashes but other type of crash. It’s all about UEFN now, because it’s problem only in particular case which is Landscape Mode - editing terrain.

uff

We have identified the issue, and it should be fixed in the next update.

When is the update coming? Same issue here tonight. It was on a map I’ve been working on, but the issue just started tonight. Crashed after a few seconds every time I would start to sculpt in landscape mode.

Hopefully soon. I have the same issue here. It looks like UEFN updates every time Fortnite updates as it looks like it is tied to the same version number (Both are currently 24.10). I would guess the fix would be on the 11th, but that is just speculation.

I also noticed that after it crashes, the map it crashes on will no longer let me use the paint tool. I’m guessing the fix will address that as well, but just throwing that out there.
