Making bullet holes not to go beyond the part boundaries

Help and Feedback Scripting Support

I have a very simple script that uses Raycast to create a bullet hole:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()

local MousePosition = mouse.Hit.Position
local origin = script.Parent.Handle.Position

local Direction = (MousePosition - origin).Unit
	
local raycastParams = RaycastParams.new()
raycastParams.FilterDescendantsInstances = {script.Parent, player.Character}
raycastParams.FilterType = Enum.RaycastFilterType.Exclude
	
local ray = workspace:Raycast(origin,Direction * 3500, raycastParams)
	
if ray then
	
	local hole = game.ReplicatedStorage.BulletHole:Clone()
	hole.Parent = workspace 
	hole.CFrame = CFrame.new(ray.Position, ray.Position + ray.Normal)
	
end

As you can see, nothing special. But it looks like this:
image

It sticks out from the part.

I know you can use Surface GUI and create Image Label there, and then everything looks correct:
image

But does anyone know how to calculate the correct position in SurfaceGUI and create an image there?

you want to calculate where a raycast intersects with a surfacegui to move a bullet hole there?

or do you want to calculate where a ray intersects with a part; what face of a part its intersecting; and how to offset an imagelabel to be where the raycast intersected

this is what he wants

first you’d have to get the face of the target where you clicked, then somehow get the offset between face origin and surface UI position. I’m not sure how to do this but if I was working on a gun system right now I’d attempt it.
