Ohh alr then create a MeshPart and then copy the meshId and the TextureId into the meshpart then ,
change the size of that MeshPart on the script for example
So is this script in the player Part Mesh inside the player in the workspace or is it in the player inside the Player service?
Also what happens if you increase the numbers in the equation in your script to exagerate the scale change just to see if your numbers are just too small. Sound.PlaybackLoudness / 1000 * 0.3 is a very small number.
(any number /1000 *.3 is the same as /300)
If PlaybackLoudness is 5 then 5/300= .0166667 so changing the scale by 1+intensity isn’t very nuch at all.
