# Objective Fixes #6030, making ``serde`` optional. ## Solution This was solved by making a ``serialize`` feature that can activate ``serde``, which is now optional. When ``serialize`` is deactivated, the ``Plugin`` implementation for ``ScenePlugin`` does nothing. Co-authored-by: Linus Käll <linus.kall.business@gmail.com>
