"Set Visibility" in Scenery Editor

[In Revolt]

I have a question about function "Set Visibility" in Scenery Editor. Object(O)>Map(M)>Set Visibility (Distance that elements become visible) opens menu
that gives you range in km. It seems that it works only with flat map elements like polygons,rectangles,runway elements,quad strips. The problem is that when i put any distance different then 0.00km the element is completely gone in game and never appears back at any distance.How this function works?How to use it?

^Would help to know which version of Scenery Editor you're using. The last known "well-working" version is the 2009 version (seems to be the consensus anyway around here).

I've never used this on 3D objects like buildings and such so I don't know if it works with those elements or not, but it does work for any kind of lights (point lights or array lights), in addition to the flat elements you mentioned. The way I do it is to select the element (in this case the array of lights or group of point lights), then go to Map > Select All Elements and then set the visibility. Do note that the visibility is set in meters, not km.

It works perfectly in both versions, but in newer there is (km) in dialog menu that confuse me.
So need to insert 1000.00 instead of 1.00 for a distance of 1km.
