Objects spawning outside designated CFrame

[ZElectricitE]

I have made a system that will spawn npc’s at a random position within a part, however npc’s have been spawning outside of the part. Although this happens on one of the 5 parts.

--Functions
local function GetRandomPos(position, xSize, zSize, ySize)
	local randomX = math.random(-xSize/2, xSize/2)
	local randomZ = math.random(-zSize/2 , zSize/2)
	local spawnAt = Vector3.new(randomX, ySize, randomZ)


	return spawnAt + position
end

local function SpawnNpc(stage)
	task.wait(0.65)
	--Npc
	local clone = npc:Clone()
	local hum = clone.Humanoid
	--Animations & Prompt
	local idleAnim = npc.Animation.Idle
	local prompt = clone.HumanoidRootPart.GiveJoke
	prompt.HoldDuration = player.Stages[stage.Configuration.StageName.Value].JokeTime.Value
	
	
	--Spawn
	clone.PrimaryPart.Position = GetRandomPos(stage.Position, stage.Size.X, stage.Size.Z, stage.Size.Y + 2.5)
	local npcAngleOffset = CFrame.Angles(0, math.rad(math.random(-360, 360)),0)
	clone:SetPrimaryPartCFrame(clone:GetPrimaryPartCFrame() * npcAngleOffset)
	
	clone.Parent = stage

This script gets the size and position of a part then returns a vector 3 for NPC’s to spawn within.

As shown here, none of the NPC’s are spawning outside of their part

Although on this one NPC’s are…

Im not sure why this is happening and I have gotten no where.

Here are all the parts in explorer if that helps

Some are also spawning within buildings, but that has to do with them not spawning in their set boundaries.

If any of the stage parts are rotated, this probably won’t work because GetRandomPos doesn’t go off the part’s CFrame, only its position.

There isn’t really enough information here beyond that to help debug.

Well It seems that the stage has some orientation set. I removed it and changed the scaling and it worked. Thank you
