Linux: Not possible to load second LOD level

Platform: Arch Linux 64 bit – NVidia GTX 760 (driver: nvidia package with version 346.59-1)
Branch: release branch (4.7.5 tag) (compiled by myself)


I was following a guide in the documentation, but while trying to import the fbx file, the file opening dialog did not show any fbx files, although they are definitely existing.
Also the title of the dialog contains an error message “Failed to import a mesh for LOD 1”.

The FBX file is ok: importing the same fbx file as LOD1 is working on Windows.

Hey -

I was able to reproduce this on my machine and have submitted this bug (UE-13581) for further investigation. For now it would be best to create the LOD’s in the modeling program before importing into the engine. This wiki page shows how do to so: FBX Static Mesh Pipeline in Unreal Engine | Unreal Engine 5.1 Documentation

Cheers

Hi - could you try this change? https://github.com/EpicGames/UnrealEngine/commit/1ea672a04105494d41735cc332a5fab5435426e2

Hey RCL,
I wasn’t able to compile 1ea672a04105494d41735cc332a5fab5435426e2 on arch linux, so I switched over to the HEAD of the master branch (currently b9f5381f9a894cdf017f28733f26652e8502db12)
There compilation succeeded, but I couldn’t start the editor because of a segmentation fault.
See the output for the call stack: link text

I am currently using the package nvidia-libgl with the version 349.16-1
Do you think switching from arch linux to ubuntu might do the trick?

Make sure you have git plugin disabled (BlacklistPlatforms should contain Linux in GitSourceControl.uplugin) - for now it seems to crash the engine in a similar way (although at head you may have other crashes too).

As for switching to Ubuntu - yeah, that would bring you on the same page with our QA and support teams.

Are you using Ubuntu LTS or the newest one?

The latest. We occasionally test on LTS though, it should work as well.

Sorry for the delay, but I had to uninstall arch linux first and install ubuntu on my machine.

Yay, loading the following LOD levels is working now :slight_smile:
Howwever I found a new new bug, but that’s something for a new ticket.
