I unfortunately don't have 3ds files for it ,do you know who was involved in this?:
http://www.unimatrix01-fs2.de/13906/home.html That's where they originaly were (this mod seems to be completely unknown here ,one Whitelight linked to it in discussion about Startrek to FS2 TC) .
I'm sure that:
A. You can be close enough to it.
I made a mission when you start as close to it as when playing Inferno.
There was no problems.
B. That's not because of distance or size.
Earth in INF works well ,I seen HTL Mars (From Cardinal's Spear) from a great distance with no problems.
C. The glith you saw is because of conversion.
I also resized one of those models (Earth) and got the same.
Not resized models aren't causing this problem.
I even posted sceenshot of this glith some time ago and that's why I asked you to properly rescale it.
Simple POF-COB-POF route will not do it "properly".
And distance in targeting box can be adjusted ,this happens always if you resize the model and use the same table.
EDIT: A new file appeard on the site since I last visited it ,you can download "Startrek_UPD" and get Bajor planet model ,It's not included in my pack.
EDIT2: I found an information that the mod is by Omniscaper and sent him a PM.
