thank you so much, but I saw that this script has a different function, I meant something simpler, which allows you to quickly switch between two different meta files during the game.
I gave the example of the PeppeProduction program because it had the F5 key which immediately injected the modified metafile during the game.
Edit Handling, on the other hand, changes individual parameters, it does not replace the entire metafile by pressing a key.
But I thank you because the program you recommended will be exceptional for simplified editing of meta files. Thanks again
