Good Morning ...This is a complicated one, so it is certainly worth the explanation, thank you for asking.
Many cabins were added in the Tongass Fjords X package. In the PFJ Service Pack 1, many more cabins were added for that area. So if you have Tongass and PFJ SP1, you have about 65% of the cabins already. Other 3rd party people have put more cabins in with "external" files that you can download from AVSIM, etc. Some of those have problems because the cabins they put in were outside the Tongass Area and in the PFJ area. The result was cabins out in the water and buried in the mountainside. I decided to fix that. I took out all of those "3rd party" cabins ... and you should do the same. Once they were out, then I started putting in the cabins that were missing, and the result is the RTMM Missing Cabins.zip file. And as Handie has pointed out, you can download that at the top of the Cabins Page.
When we send you a folder, do not worry about what is IN the Scenery Folder ... all the bgl files, etc. They will only be understood by the developer who knows how they were put together. But this is a good one to explain so people can better understand what developers are doing and what the "bgl" files are in the scenery folder.
There were two shelters that RTMM put in that PFJ SP1 had not added. These were Nooya and Punchbowl shelters. We had an addon that added them (USFS_Cabins.zip). I put those two bgl files into this new folder. Also, Brad had created 5 missing cabins ... we had those as separate downloads. With his permission, I added his cabins to this folder too. So you will see his cabins, Nooya and Punchbowl shelters and a missing cabins bgl. I put all the other cabins and shelters into the rtmm_missing_cabins.bgl. You can see what's in the "scenery" folder attached.
In the Readme that comes with the package, I mentioned there are THREE things which people must do to make this work:
==================================================================
NOTAM #1: If you have installed Brad Allen's Missing Cabins, you must delete those from the scenery library. They are:
Honker Lake Cabin
Salmon Bay Cabin
Salmon Lake Cabin
Sarker Lake Cabin
Sweetwater Lake Cabin
These 5 locations are now INCLUDED in this package, so you will still have Brad's work. Go into your scenery library and either uncheck them there or do a “DELETE AREA” on each of them.
NOTAM #2 Also there are some third party “missing cabins” files that are offered by other people. You should also uncheck those locations or delete them. If you do not, you will have double cabins in most areas.
NOTAM #3 If you have the “USFS Cabins” scenery folder (downloaded from RTMM), you must delete/deactivate that folder too. This includes Nooya Lake Shelter and Punchbowl Lake Shelter. Both of these are in the new “RTMM Missing Cabins.zip” file.
======================================================================
Many people have put in Brad's cabins, and many also put in the USFS Cabins folder that had added the Nooya and Punchbowl Lakes. Also many had put in Jurgen's TongassX Cabins.zip. These are all the ones that must come out (or there will be duplicates). There are two or three other "missing cabins" files out there on the internet that people might have put in ... if you have installed any of those, they must come out or you will have duplicates.
In summary ... If you have Tongass Fjords X, PFJ with Service Pack 1, and RTMM Missing Cabins ... then you now have a complete set of all the USFS cabins that are listed on the USFS website. All of them "work" are where they should be and are roughly the correct "kind" of structure. All of the cabins are documented on The Cabins web page with structure and mooring latitude and longitude, pictures, maps and 1200 autopilot flight plans.
I hope that explains what we are doing. The key is, don't pay a lot of attention to what is in the "scenery" package. With all the flattens and other things we can have in there in many packages, it can become very confusing to even other developers who know what they are seeing. But DO pay a lot of attention to the README files ... that's where the "magic" happens for the users. If we get it "right" here at RTMM (and we do make a mistake here that we quickly correct), people won't have to worry about what is in that scenery folder if they follow the readme installation instructions. And when they put it in, if they follow the instructions ... it works ... (and if it doesn't, folks let us know and we fix it quickly).
Hope this helps
Doug
