It would be pretty cool to see some discord implementation. Basically what we did with Steam It might be easy to convert over but I don't know. What you see is the car your driving, the level (possible icon?) and that's it.
Maybe with the program it could look for a picture with a specific name or something? I'm not sure. Maybe just official cars for now. I also meant maps but ok.
I think there was a mod made by @Dummiesman that allowed this. I just don't remember what happened to it.
Discord rich presence can't take images at runtime, they're predefined on Discord's side Also I last updated my mod recently and it worked just fine for me.
If its discord only then I cant get it cause I've been banned from bomboys server. I tried the outdated version and it doesn't work.
Latest version is here https://beamng.com/threads/discord-rich-presence-for-beamng.52581/ Just re-tested and it's working fine
