Load map without move the character

Hello, I try to load a place of the map without moving the character because as you know certainly, GTA loads only places close to the character whom we play to optimize the game. And I would want to know without moving this character, asking a precise place of the map then to unload it then. I have already tried “LoadScene” but it doesn’t work. (sorry for my bad english)

I have found: void _SET_FOCUS_AREA(float x, float y, float z, float offsetX, float offsetY,
float offsetZ)
