General Question Markers DistanceFactor

[vchamp]

How this DistanceFactor parameter is supposed to work? I'm trying to make markers that show up only when I'm less than a few kilometers from them. In my scenario I start somewhere about 10 km from the markers in the DeltaGlider flying towards them. If I set DistanceFactor to 0.17 markers are visible from the start. Then I change the factor to 0.16 and markers don't appear regardless of how close I am.

This is the mkr file's header:

BEGIN_HEADER
InitialState on
ShapeIdx 6
ColourIdx 2
Size 1.0
DistanceFactor 0.16
END_HEADER

In OrbiterConfig.pdf it is said that the interval for DistanceFactor is [1e-5 .. 1e3], but setting it below 0.17 makes markers not appear at all.
