# Objective It's not immediately obvious that `TargetCamera` only works with UI node entities. It's natural to assume from looking at something like the `multiple_windows` example that it will work with everything. ## Solution Rename `TargetCamera` to `UiTargetCamera`. ## Migration Guide `TargetCamera` has been renamed to `UiTargetCamera`.
