Fixing VR Controllers Out of View

If you use inside-out #VR / #WindowsMixedReality headsets like @Samsung Odyssey, you'll run into the controllers glitching out when out of view (below or behind your head). In an #UnrealEngine or #Unity game, a workaround is to store the location of the controllers but avoid updating if the location moves too far from the headset (the glitching out when out of view). The rotation of each controller still works as they're based on gyroscopes instead of cameras, so you'll still want to update the rotation, just not the location which is now some absurd unusable number.

In Unreal Engine, it would look like this:


This really should be internalized into the headset driver itself, as it only makes sense to not update to a location that is physically impossible.  For now, you have to do that check yourself.
