So, I tryed using TDUF to change the FOV in TDU. This is an abit that I developed in the sim racing community, trying to use a realistic FOV for better immersion and driving.
Starting from this guide (https://github.com/djey47/tdu-cp/wiki/TDUF-Database-Editor-Cameras), I was able to determine that "binoculars" is the actual value that controls the FOV.
Using just small changes to te last two digits, I was able to alter the ingame FOV.
Here are some results obtained with the "Ferrari LaFerrari" from TDU Platinum MOD.
@Djey also added some interesting details in another thread:
So, if anyone is interested in changing the FOV for TDU, I could use some help in actually relating those values to the actual FOV degrees values.
