How do I use BodyHeightScale on a custom starter character?

[TwistyO8]

1. What do you want to achieve?
   I have written a script that increases a player’s body proportions by a certain amount when they join the game. However, when I replace the starter character with a custom character, the script runs correctly but the character does not scale correctly.

2. What is the issue?
   The issue is that when the player starts resizing, it is done incorrectly. Please see the video to observe the problem.
   

3. More Information

Scale function

function alterLimb(limb)
	-- Select a random alteration type
	local alterationTypes = {"Scale Increase"}
	local alterationType = alterationTypes[math.random(#alterationTypes)]

	-- Alter the limb based on the selected alteration type
	if limb.Name == "HumanoidRootPart" then
		-- If the limb is the HumanoidRootPart
		if alterationType == "Scale Increase" then
			local humanoid = limb.Parent:FindFirstChild("Humanoid")
			local currentBodyDepthScale = humanoid.BodyDepthScale.Value
			local newBodyDepthScale = currentBodyDepthScale + .1


			local currentBodyWidthScale = humanoid.BodyWidthScale.Value
			local newBodyWidthScale = currentBodyWidthScale + .1

			local currentBodyHeightScale = humanoid.BodyHeightScale.Value
			local newBodyHeightScale = currentBodyHeightScale + .1

			humanoid.BodyDepthScale.Value = newBodyDepthScale
			humanoid.BodyWidthScale.Value = newBodyWidthScale
			humanoid.BodyHeightScale.Value = newBodyHeightScale
		else
			print("Invalid alteration type: " .. alterationType)
			return
		end
	end
end

The issue here is probably the hip height. The default hip height is 2, and for R6 it is 0. Why is it negative?

However, you can probably adjust the hip height accordingly in the script you have.

**The script runs correctly but the character does not scale correctly when the HumanoidRootPart is scaled.

This is a scripting issue
I have checked the Scripting Docs and searched and could not find a solution.

This issue is reproducible

I have attached a video and created a custom character and script to illustrate the issue.

How to reproduce this issue

Please follow the instructions below to reproduce the issue

Create a new empty place
Add a custom character with a HumanoidRootPart
Create the following script and add it to the ServerScriptService

function alterLimb(limb)
– Select a random alteration type
local alterationTypes = {“Scale Increase”}
local alterationType = alterationTypes[math.random(#alterationTypes)]

-- Alter the limb based on the selected alteration type
if limb.Name == "HumanoidRootPart" then
	-- If the limb is the HumanoidRootPart
	if alterationType == "Scale Increase" then
		local humanoid = limb.Parent:FindFirstChild("Humanoid")
		local currentBodyDepthScale = humanoid.BodyDepthScale.Value
		local newBodyDepthScale = currentBodyDepthScale + .1


		local currentBodyWidthScale = humanoid.BodyWidthScale.Value
		local newBodyWidthScale = currentBodyWidthScale + .1

		local currentBodyHeightScale = humanoid.BodyHeightScale.Value
		local newBodyHeightScale = currentBodyHeightScale + .1

		humanoid.BodyDepthScale.Value = newBodyDepthScale
		humanoid.BodyWidthScale.Value = newBodyWidthScale
		humanoid.BodyHeightScale.Value = newBodyHeightScale
	else
		print("Invalid alteration type: " .. alteration
