UE 4 and 5 VR Problem

Hi,
How can i Fix the VR range problem ?

A fightership in the 20km Engine Map is no problem, but after the 20km the Cockpit starts to shake and the Buttons move from there positions.

I try world Composition… Fail
with rebase… Fail
some BoundsBoxes ( Levels )…Fail
I change the Engine Map max size in C++ …Fail…after 20km the same problem.

Then i use the fightership in the UE5…same problem at all.

BUT when i use the same Jet and start in Viewport or Window PIE , i can flight 2000 Km without any problem.

Question :
How i can change the VR Max range ? if there is one ?
