I had several requests how to get a track into developer mode. So here we go. What you need. 1. MAS2.exe The tool is located in your rFactor2 datafolder (…rF2DataFolder\Support\Tools\MAS2.exe). Create a shortcut on your desktop. 2. Editor like notepad. Try Notepad++ (download at http://notepad-plus-plus.org/) In this example we extract the ISI Monte Carlo track to developer mode. 1. Launch MAS2.exe and select “file” – “open”. 2. Navigate to the installed track you would like to import into developer mode. In this case it is “rFactor2Data\Installed\Locations\MonteCarlo1966\1.0”. 3. You can see the names of the mas files for Monte Carlo. Now it’s time to create the folder structure inside ModDev. Open a new explorer window and navigate to “rF2DataFolder\ModDev\Locations”. There should be a folder for Joesville. Now create a new folder for “MonteCarlo”. Inside the MontCarlo folder create two new folders (“Assets” and “MonteCarlo_1966). Inside the Assets folder create the folders “Anims”, “GMT”, “Maps” and “SponsorMaps”. 4. With the folder structure ready we now can extract the contents of the mas files. Open the first mas-file, select all files (CTRL + A), rightclick on a selected file and click extract. -MonteCarlo.mas to ModDev\Locations\MonteCarlo -MonteCarlo_1966.mas to ModDev\Locations\MonteCarlo\MonteCarlo_1966 -MonteCarlo_Anims.mas to ModDev\Locations\MonteCarlo\Assets\Anims -MonteCarlo_GMTs.mas to ModDev\Locations\MonteCarlo\Assets\GMT -MonteCarlo_MAPs.mas to ModDev\Locations\MonteCarlo\Assets\MAPs -MonteCarlo_SPONSORMAPs.mas to ModDev\Locations\MonteCarlo\Assets\SponsorMaps 5. We are almost there. You can close MAS2.exe now. In Windows Explorer navigate to “rF2DataFolder\ModDev\Locations\MonteCarlo\MonteCarlo_1966”. Open the file “MonteCarlo_1966.scn” with a texteditor (Notepad, Notepad++). You should see something like this. Check the searchpath’s inside your ModDev\Locations folder, they should have exactly the same names. If not, rename them to the names of the scn-file. The folder “MonteCarlo_1966” is for the specific layout of the track. When you have more layouts, like limerock, each layout has its own folder. 6. Final step. To make sure your track is selectable with the rtrainer mod you have to edit the filter properties of the gdb-file. In Windows Explorer navigate to “rF2DataFolder\ModDev\Locations\MonteCarlo\MontCarlo_1966” and open the file“MonteCarlo_1966.gdb”. Find the line “Filter Properties = historics” and add TMOD to the end of the line (don’t forget the space between “historics” and “TMOD”). Save the file. TMOD is the specified “Track Filter” in the rfm-file of the mod. In case of rtrainer you will find the file at “rF2DataFolder\ModDev\rFm\TestingMod.rfm”.
If you don't use the TestingMod (which is tagged as TMOD int the rFM) you can just drag & drop the main track folder from the installed locations into the devmode/locations and it works fine. The only problem is you can't use track cams.
