For the BOTI Paintings (like Gallifrey falls no more paiting) make it so you can hide inside of it like the 3 doctors / zygons did in that episode of doctor who and players can move it whilst your still inside and you can come out whenever you want

it wouldnt really work since you cant see entities in it you can only see blocks so maybe it could leave a statue when its saved but the statue is removed and it would dissapear when you come out
