[Bug] Changing Instanced Foliage Settings don't refresh instances on the scene

There is a problem with refreshing instances when making changes to InstancedFoliageSettings file attached to one or more meshes. Let’s assume we have two such meshes, both sharing the same file with settings. I tested it mostly on culling, so something I’m not able to reapply through “Reapply” tool (or at least it doesn’t work now).

  1. Changing a value of culling in the file directly (through UE editor of course) and saving the changes make the new values show in the foliage meshes list as well. But instances on the scene don’t change. I need to put on the list, individually in each mesh, a new value, then return to the one I’ve got in the file to make the change apply to instances already placed.

  2. The same goes for making the change directly on the list. Values change for both meshes on the list and in the file itself automatically, but instances of only the mesh we were writing on change on the scene.

Also I think it should be mentioned somewhere, that attaching the same Settings file to a group of meshes on the list make them activate or deactivate all at once.

Hi Nox,

Thank you for your report. I have been able to reproduce this and will attach this along with my findings to a bug report. Have a great day!

Why mark this solved when it’s still an issue in Unreal 5.3?
