Heightscale doesn't work on R6?

Today I was trying to change the scale of my character when I realized my height scale wouldn’t change

local Description = Humanoid:GetAppliedDescription()
Description.HeightScale = Description.HeightScale*2
Humanoid:ApplyDescription(Description)

Did I do something wrong or is it not a thing to change the players height

Height scale only works with r15 avatars.
Its gonna be complicated If you want to change the height of the r6 avatar, you have to scale each part to make it work.

As has been stated, only R15 rigs can be scaled via the HumanoidDescription’s scale properties.
