Как спрятать и показать 3d-объект в дополненной реальности с единством?

Question

Я создал дополненную реальность с помощью пользовательской цели (пример ядра Vuforia).
Дополненная реальность работает нормально, но я не могу скрыть и показать 3d-объект в единстве. Я использовал код setActive (false) для объекта, но не работает в приложении для Android. Я хочу реализовать это в Android.
