Brian, your description of your problem is a little vague, but yes, scenery order placement could be your problem. What, exactly, were you installing from ORBX? First of all, FTX Central should not be running while FSX is running. Shut the sim down, run FTX Central and check your scenery library again. Did you apply the Insertion Tool in FTX Central b4 installing the ORBX scenery? If not, it will go to the top of your FSX scenery library. That's not where it belongs. I posted this for somebody else just a little while ago, but now I keep it handy
Your scenery library order should like this, and in this exact order:
3rd Party Scenery (RTMM and any others you may have) at the top
OZX Entries (if you have any)
FTX Entries (all of your ORBX add-on entries preceded by FTX)
Tongass Fjords High Priority (if you have Tongass)
Tongass Fjords Low Priority
ORBX OPEN LC entries
Default Edwards AFB down to and including Africa. Below that:
ORBX Vector entries, followed by:
FS Global entries. Followed by the rest of the default entries.
If you have not set your Insertion Points, any new FTX or OpenLC entries will install at the very top.
Hope this helps, keep us posted.
