Objects disappearing half way when camera moves away

Hello! $$anonymous$$y best guess is the render queue of the objects. For some shader when you render objects the engine checks the centers of the objects with some precision, and then draws them on top of each other regarding this value. $$anonymous$$oving the camera further increases the error calculating with these values and maybe this causes the problem. As I know if the engine can't decide correctly the distance, it draws, regarding their place in the hierarchy. Try changing the order of the objects. I'm not 100% sure it is the case but maybe. To solve try using smaller objects, as I think it solves the problem.
