Is it possible to create your own set of rules as well as the type of damage that affects the vehicles ?
I think some rules you can via custom rfm when creating your vmod, I'm not well versed in it, so I'll leave it to others to comment
The rfm file can be altered and that sets general guidelines for a series/mod. The gbd file allows setting for each track and will override the rfm. Here is the thread that will get you started https://forum.studio-397.com/index.php?threads/description-of-possible-parameters-in-gdb-file.45198/
Thanks a lot there is a lot of good info there, I was meaning more in relation to what type of damage comes up in the session list of a race like suspension or engine or chain came off stuff like that, that is probably set much deeper in the software and something we cant edit. Working on a Kart mod and it would be great to be able to have chassis damaged instead of Suspension or Chain came off instead of Gearbox and that sort of thing. Cheers. Maybe that is something in the future that could be synced with the damage file, some sort of custom damage names.
