Custom mesh is full broken in v32.00 Fortnite and UEFN crashes when opening project

Summary

We have a Halloween tycoon 8067-5275-3354 out that has been working fine up until v32.00. Now the project can’t be opened without UEFN crashing and the game’s custom mesh is full broken with collision lost as well.

Others have noted that this is due to LOD being changed in fortnite and UEFN. Setting UEFN to launch with DX11 in “custom launch settings” can open it, but there doesn’t seem to be a way to revert the mesh back to the way it was initially. This has full tanked our map and killed any momentum it had. Disappointing.

hi,
There is a more complex post about a new legacy mode for Island and Assets earlier than 30.00
CRITICAL - UEFN session not start in Fortnite (map testing not possible !!!) - General / Issues and Bug Reporting - Epic Developer Community Forums

But it broke without doing any updates. With the new Fortnite version the custom assets are just broken, not just in UEFN. So it’s not even something we changed or didn’t change and then published, the map is just full broken from the update. Unfair and seems really irresponsible to destroy somebody’s general income without notice.

Hi
Well this is fairly obvious, My skill is the UE5 engine. So no idea why its broken.

Walks through the ramp not up the ramp

Oh dear leaves missing body!

ya… but my point is that it never looked like that before. The LOD has completely busted and the collisions have gone with it… this is what it looked like before the update (without any input from us from the day before to now. We haven’t touched a thing)

for direct comparison of the same view after v32.00

We’re not the only ones with this issue, but this is an absolute game killer unfortunately for us without any mistake on our part.

hi
This UEFN/Fortnite documentation for LOD
Dont really understand
