UE 4.10 Foliage Disappearance Bug

UE 4.10 Landscape learning tutorial map unmodified. Download, start in standalone or new window, and fly toward trees. Trees will vanish based on camera angle regardless of distance. You can crash into invisible trees as seen in video. Even removing the other LODs and auto LOD generation doesn’t seem to resolve it. Works perfect in 4.9. Convert the 4.9 version of this project to a 4.10 and problem reappears there too.

Hi ELorenzen,

I’m not sure exactly what is causing the issue in 4.10 after looking at it for a bit, but looking at the project in the build that will become 4.11 when it’s released does not have this issue.

As it stands this looks to be resolved in that build and I don’t see any JIRAs that were entered that reported the issue.

Thank you for taking the time to submit the question and look for this to be fixed in that future release.


I’m facing this bug also but I’ve found you can fix it for the most part pretty easy if you need to in your project. At least the following worked for me, don’t know if it will for you.

Add the following under the BeginPlay for your character (or really, for just about any actor)


It seems as though once one is removed (possibly under other conditions?) it updates the rest of them and then the foliage is back to normal.

Thanks, I’ll give this a try and see if that fixes it.

I tried plugging a different mesh into the slot of whatever foliage was missing, save the map, re-open the map and re-apply the static mesh to that foliage layer that used to be there and it started displaying again.


replace disappeared foliage layer w/ any mesh → save map → reopen map → apply intended mesh back in that foliage slot.

DylanBrady’s solution worked for me… but WHY does it work… and why is it needed?

As Tim Hobson stated in his initial post, this has been resolved in the preview release, so expect this fix to be integrated when the full release hits the public.
