I have created this Guide for the JSON entry of "Autocalibrate", this basically helps the AI learn a given track and save their Learning Process for future usage. I will be detailing both the
"Autocalibrate AI Mode":1 and
"Autocalibrate AI Mode":2 processes.
(I may make additons, fix errors in future, if so Post #2 will detail what has changed)
Before I begin here's a few notes:
- You don't need to do any of the AI Learning if the AI are just fine at a track, more often than not it's 3rd party Tracks that need it or if a particular Mod has difficulty in a corner or section of a track that you're racing at.
- Remember the AI make mistakes (there is a setting in the JSON for this). If you see AI occasionally spinning at a corner then that's ok, you don't need to panic and jump into the Learning Process to make them 100% Clean every lap. The beauty of RF2s AI is that they are very Human like....so they make mistakes!
- The Tracks AIW file (this is what the Track Author creates to give the AI a Basic Driving Line) is a
Major key factor in both Learning processes, no amount of AI Learning will prevent the AI crashing if the AIW is poorly created.
-
"Autocalibrate AI Mode":2 can have the tendency to create much faster AI and to a point where they become "too good", if (like me) you want AI to reflect Humans as best as possible (i.e. they make Mistakes) then either run fewer laps with this setting or don't run it at all. As per the first point you don't have to do any Learning, this guide is merely for those times where it is needed should the AI be struggling.
- Both #1 & #2 use Different algorithms, this means that #1 may actually work better at some tracks than #2 and vice versa.

For the Guide I'll be using the latest ISI Renault Clio 2010 (v1.51) mod at Mills Metropark (v1.43) 'Layout Inner Loop C'.
AI Learning Guide #1:
"Autocalibrate AI Mode":1,
1)
Locate your
player.JSON file in your '\RFactor2\UserData\player' (yours may differ if you chose Default Dir when installing) and open with Notepad or preferred JSON editing tool.
Search for and locate the following:
"Autocalibrate AI Mode":0,
In this Guide we will be using the "1" variable so go ahead and change the 0 to a 1. (NB: Make sure your player.JSON isn't Read Only) Save and exit Notepad then Load RF2
2)
The in Game settings are important, so setup as follows (Picture for reference):
- Make sure to select
PRACTICE ONLY
- Set the Weather to Sunny or Overcast, as long as there's no Rain at all
- Turn
OFF Tire, Fuel and Mechanical Failures. Set the Strength to 100% and Aggression to 50%
- 0 AI Selected

3)
OK here we are at the track, go ahead and ADD 1 AI (Important: Only 1 AI), in the Chat Box you'll see a friendly message from the AI telling you to pretty much sit in the Garage and not move:

Now during His or Her learning process he or she will drive lap after lap and gradually you'll see the "I can do better" message scroll down until the "Meters" gets to 0.00 or as close too it. Sometimes they finish Learning before they reach 0.00 so don't worry if they do:

Depending on the Track and/or Mod the AI might have difficulty in finishing the session, for example they might get into the 20.0meters range and constantly loop around that Number. If this happens type in FINISH into the chat box and you'll get the following message:

Once they have Finished Learning you'll see the "Track Learning Succesful" message, you can now exit the track and that's it, they have learnt the track and are ready for Racing.
4)
For Confirmation go to your \RFactor2\UserData\player\Settings\ISI_Renault_ClioCup_2010 folder and you'll see a List of the Cars (or just One) and their respective Folder. Inside one of the Folders there will be the following file:
MILLS_INNERLOOPC.ini
This indicates the Learning Process was completed.
5)
For this file to work with all cars you have to manually copy the INI file to all the other Individual Car Folders, this way each individual car will read the same MILLS_INNERLOOPC.ini file when the track is loaded.
Finally go back to your player.JSON file and set Autocalibrate back to 0:
"Autocalibrate AI Mode":0,
Important notes on this setting:
- If you're running a Multicar Mod then you will have to do the process for each type of Car.
- If the AI crashes before completing then simply Boot him out and ADD a new one (just 1 remember), if he crashes and fails to complete the process it could be the fault of the AIW, this Process is not a Perfect Cure for a poorly create AIW file.
Another question that came up is what to do if have both .ini and .wis files such as when you try method 1 first but don't get good results so then use method two. Not sure which the engine gives priority to so I just deleted all the .ini files so might also be good to mention if it is known which takes precedence or it is recommended to not have both etc etc. Thanks again for pulling this info together. Should be a sticky. Now to read the test of the thread
