I want to fade the player when he goes out of the area.
For example, suppose a person enters a building. When a person is outside of the building, he shouldn't be seen, but when he enters he gradually becomes visible (using fading effect).
when elephant is inside green area his alpha should be 1
when elephant is outside of green area his alpha should be 0

You can use world space to fade your character.
The object space (or object coordinate system) is specific to each
game object; however, all game objects are transformed into one common
coordinate system — the world space.
If a game object is put directly into the world space, the
object-to-world transformation is specified by the Transform component
of the game object.
