* Unified all invalidation/update code paths so that we respect landscape.LiveRebuildNaniteOnModification in all modification cases * Made NaniteComponent non-transactional and invalidate Nanite mesh upon undo (no need to clutter the transaction buffer with heavy redundant data) * BuildNanite is now able to build either all proxies, like before, or only proxies from a list (including streaming proxies, in the case of a ALandscape) * Build Nanite data can now be done per landscape proxy actors, allowing the user to update only a list of select actors (supports multi-selection) * Added Rebuild Data button to landscape proxy actors to force building the Nanite data even if the content has not been detected as having been changed * Landscape proxy actor details now supports multi-selection and allows to display landscape details only if all selected proxies are share the same parent ALandscape * Fixed Nanite landscape which would fail to build at 64 components (while it actually supports up to 64 components) * Fixed NaniteLODIndex, which would show in the details panel even when Nanite landscape is not enabled * Added progress bar when building Nanite from the details panel buttons * Disable navigation data on Nanite landscape static mesh #rb chris.tchou #preflight 637cec082a05dabce96cf332 [CL 23243849 by jonathan bard in ue5-main branch]
