NPC Sit Pose Not Showing

So I’ve use this script to make my NPC sit,

game.Workspace.Chair["School C hair"].Seat:Sit(game.Workspace.Helza.Humanoid)

it does the work but the sit pose is not showing

How can I fix this issue?

Hello? Can someone help me with this

you need to play the default sit animation…

You need to play an animation ID

I’m pretty sure you can find the r15 default animation

Oh, Okay then, thank you so much

Still the same

I use this code

local SitAnim ="Animation")
SitAnim.AnimationId = ""
local controller = game.Workspace.Helza.Humanoid
local Animation = controller:LoadAnimation(SitAnim)

Can anyone help me with this?
