Try to search for “scale model” and you’ll find something like this:

Is this the best way to scale a model?

I’m trying to scale trees to give more foliage variation in my game. The code I’m using is shown below. It works fine. But is there a better way? Is this the best way? Considering I’m trying to run this function on 10,000 items as quickly as possible, I’m trying to figure out if there’s any way to speed this up. local function ScaleModel(model, scale) local primary = model.PrimaryPart local primaryCf = primary.CFrame for _,v in pairs(model:GetDescendants()) do if (v:IsA("BasePart")) t…

Pretty sure you can model the parts and just scale the model in a script.

Thank for the script but there are a bug: affected parts may have bad orientation so, if you are reading this topic, please use this script instead.

local function ScaleModel(model, scale)
	local primary = model.PrimaryPart
	local primaryCf = primary.CFrame

	for _,v in pairs(model:GetDescendants()) do
		local orientation = v.Orientation
		if (v:IsA("BasePart")) then
			v.Size = (v.Size * scale)
			if (v ~= primary) then
				v.CFrame = (primaryCf + (primaryCf:inverse() * v.Position * scale))
			end
		end
		v.Orientation = orientation
	end

	return model
end

Btw just in case you have say a Billboard Gui in the model and use :GetDescendants then it will still try to get the orientation of it which will therefore error so just to stop that you would need to put it like this

if (v:IsA("BasePart")) then
    local orientation = v.Orientation
	v.Size = (v.Size * scale)
	if (v ~= primary) then
		v.CFrame = (primaryCf + (primaryCf:inverse() * v.Position * scale))
	end
    v.Orientation = orientation
end
