All you have to do for that model atleast is replace the bit after rbxassetid:// with the new number and press save and it will be updated.
The animation only works in R15 caracters but not on R6, how do i make all the leaderboard caracters R15 so it can play the animation?
Choose R15 here.
I did that but the characters that are R6 don’t change to R15.
You Might have to contact the model’s creator about that if you can then.
