Coming soon.. but now two add-ons: one for P3Dv4x and a different one for P3Dv5 due to the different elevation adjustments and the different airport database in P3Dv5 as compared to the tables in P3Dv4x and lower. This required additional customizations to some scenery pieces for use in P3Dv5 - and are not compatible with P3Dv4..so two different add-ons.
Both the RTMM Add-on for P3Dv4 (any version) and the RTMM Add-on for P3Dv5 are complete and are in final beta testing this week. Expect to release these add-ons here on the RTMM site next Saturday (August 1st).
The RTMM add-on includes a full user guide, ai traffic, scenery switcher plus a section in the guide on how to setup tongass as an add-on, terrain.cfg tongass entries, scenery order/layering, insertion points etc. etc. Much more info coming soon.
Note: the RTMM add-on for V4 as well as V5 requires tongass correctly installed and in it's folder structure. More details on this later in the RTMM add-ons guide.
In the meantime when I get to my PC will post a tongass fjords x add-on.xml file here (Text as well as a zip containing the XML file). If you install tongass to an fsx dummy install folder then move all the folders to your add-ons folder under a master Tongass Fjords X folder- and maintaining that installed folder structure in the sub folders then add-on xml can be used as a guide containing all of the required entries. Will probably have to update the path of the entries in the add-on.xml to match your actual default documents\Prepar3D V5 add-ons folder but not hard to do (edit with notepad). Anyways will post the add-on as soon as possible.
