Visual issue when packaging project

Hi everyone,

I have packaged my project following a bunch of tutorials on 5.7 to test my proggress, and everything works perfectly minus a pretty big visual bug in one room of my level.

There are unexpected meshes visible that do not exist in my editor, and that do not have any collision.

See comparison below:

Any idea what could be causing this?

Hello there @White24Room!

Checking with my peers, and considering this only happens in the packaged build, those orange meshes look like proxy geo associated to World Partition/Hierarchical Level of Detail, which usually has no collision whatsoever.

If your scene was initially build using HLODs and placeholder props, which were later deleted, it’s possible that part of that data is still present. And if said assets are still lingering, they can show up when you package the project, cause they may not be visible in Editor, but they are still “there”, in that particular room.

The fix should be simple, check your WP settings for that level, and click on “Build HLODs” to trigger a rebuild. If the artifact remains, the other option is to delete the HLOD actors that are no longer needed, then package the project again.

For more data and practical examples on handling WP and HLODs, please check the docs below:
