Hello wang161x, that is supposed to be a bulleted list. It should read:
- Foliage
- Landscapes
- USD actors
- Console variables
- Components added to Actors, either instanced components manually added using Add Component, or components added by construction scripts.
It will be fixed in the next publish.
Unfortunately, yes, at this time you cannot use the level snapshot feature to track Foliage Actors or Landscape Actors. You will need to manually save your levels to do so.
