Impossible add new features to a group of objects on the scene

[Archinect]

If you add a group of objects to a folder, you can not edit their features all at once, only separately. It's very slow.

Are you talking about entities or assets? We are aware than multi-editing has some issues. We are working on fixing them before the official release. Sorry for the inconvenience.

Also note that prefabs (resp. archetypes) can help you share properties between entities (resp. assets).
