Content Directory builds are properly stripping LODs and Editor-Only Objects from a scene before calling the scene build callbacks and batching the static meshes.
Release Notes Search
Search changes, fixes, and known issues across Unity releases.
ContentLayout.json (produced by content directory builds) now includes an OutputLFID field on each LoadableObjectIds entry. Previously only the source object's identifier was recorded, so tools could not correlate a loadable with its exact object in the build output without also reading BuildManifest.json. The ContentLayout.json schema version is now 2.
Fixed an issue where VideoClips referenced by Content Directory builds failed to load at runtime on macOS.
Moved "Enable MSBuild Compilation" project setting into editor's pane.
