So I have this animation that basically looks like smaller parts growing out of a big part. I want it to be some kind hand/blade weapon thingy. Using this script I made:

local source = script.Parent -- the part where parts will grow out of


function growAniamtion(source, speed, multiplier, multiplier2) -- the animation function
	local part1 =  Instance.new("Part", workspace) -- the first part to grow
	part1.CFrame = source.CFrame
	part1.Size = source.Size
	part1.Name = "part1"
	part1.Anchored = true
	
	while part1.Size.x <= source.Size.x and part1.Size.z <= source.Size.z and part1.Size.y <= source.Size.y*multiplier do --animating, while the part is smaller than the source part and while it is not taller than the source height * multiplier
		wait(speed)
		part1.Size = part1.Size - Vector3.new(0.2,0,0.2) -- lower the size
		part1.Size = part1.Size + Vector3.new(0,0.2,0) -- increase the height
		print(part1.Size)
	end
	
	local part2 =  Instance.new("Part", workspace) --the second part to grow
	part2.CFrame = source.CFrame
	part2.Size = part1.Size
	part2.Name = "part1"
	part2.Anchored = true
	
	while part2.Size.x <= part1.Size.x and part2.Size.z <= part1.Size.z and part2.Size.y <= part1.Size.y*multiplier2 do
		wait(speed)
		part2.Size = part2.Size - Vector3.new(0.2,0,0.2) -- lower size
		part2.Size = part2.Size + Vector3.new(0,0.2,0) -- increase height
		print(part2.Size)
	end
end

growAniamtion(source, 0.8, 1.5, 1.2) --executing the function

This works fine and gives me this:

However If I rotate the source part then the animation gets messed up:

What can I do to remedy this?
