Hmmm im using VS core engine and it seems to work on my end.
Try entering Input.keyMapper in the F8 console and check if your custom keyname is still there
it does not work, so, I can go into the option in game and rebind the keys to whatever I want and the custom keys appear however, it doesn't seem that it lets me actually change any of the keyboard controls in the plugin parameters itself, there's a possibility that my project in bugged so I'm going make a new project and transfer everything and see if it works then
Yeah, so my project was 100% bugged, the plugin seems to work how it's supposed to now, however I did notice that Input.isTriggered doesn't seem to work, nevermind, I figured out the issue, atleast on my end, if you want to change default control schemes, you have to clear the configure file in your saves folder and start a new game
