This is the script I put in the model which is an npc
print("Hello world!")
local animation = script:WaitForChild('Animation')
local humanoid = script.Parent:WaitForChild('Humanoid')
local dance = humanoid:LoadAnimation(animation)
dance:Play()
In there, is an animation with the id

first thought is to check if the animation is for R6 or R15
not sure how do u tell
Pull up the animation editor, and select the rigs of R6 and R15 dummies, and try to load it on both of them; I'm sure you'll find out
