Help with auto set Hip Height

[GameMaster4268 (Game)]

I want to automatically set the hip height for my npc.

My current code:

local character = script.Parent
local humanoid = character:WaitForChild("Humanoid")

local function recalculateHipHeight()
	local characterSize = character:GetExtentsSize()
	local newHeight = characterSize.Y/2
	humanoid.HipHeight = newHeight
end

recalculateHipHeight()

What isn’t working with the code segment provided?

I got it to work by resizing the humanoid root part to the model size.
