FTX looks for my "African Airstrips Adventure" entry and puts FTX just above it. If I move AAA down (or up) the list, FTX would still load just above it. So whatever entry you tell FTX to insert itself above, should remain below "ALL" RTMM entries. There is no insertion point for RTMM, except that you DO go below the libraries, but not below FTX. OZx is installed just above FTX, and I don't think I ever messed with that insertion point, so really there is only one "insertion point". So make sure your RTMM entries are together, and above FTX, and all your NON Orbx entries are BELOW FTX. Then, the TOP entry of the Non-Orbx entries becomes your FTX insertion point. Any "non-orbx" scenery that you install needs to be pushed down beyond the FTX entries. And as you can see by mine, it's a long way to go. I have over 200 entries above FTX. So that is all RTMM and FTX compatible sceneries I have installed above FTX. Then all the stuff I had before FTX is below there, approaching the 300's. My library is pretty big, I think.
