Create a union, set its RenderFidelity to Automatic, zoom out 500 studs, and notice that the union is the same quality.
Expected Behavior
The union should decrease in detail the further from the camera it is, just like this option does for MeshParts.
Actual Behavior
The union’s quality remains the same. The ship in this gif has most of its unions set to Automatic, and yet its quality is not reduced when I zoom out, despite the MeshPart trees in the background doing so
Workaround
I could use MeshParts instead, but sadly UV mapping hulls of ships manually is an insane amount of work and it is much easier to just use unions for what I want to achieve. I’ve also tried setting the ship unions to Precise and back to Automatic, thinking it was just because they are relatively old unions, but it did not fix the issue.

Hi @vetexgames, Automatic is designed to utilize LOD while maintaining mesh quality. The effectiveness of LOD visualization hinges on the mesh’s quality. If game performance is a concern and you need to activate LOD when the camera is far away, please set RenderFidelity to Performance.
This bug report should be re-opened, it has not been solved. It is not possible to change the RenderFidelity property of a UnionOperation class to Performance.
Hey, thanks for reporting this. From what I can tell, this is either a bug in the LOD selection or in the LOD generation. Are you able to send us a file that reproduces this issue, that would expedite fixing the bug.
Here is a repro place, not much in it but a MeshPart and Union. You can select Performance RenderFidelity for the MeshPart, but it is not an option for the Union.
