I am trying to make a script that highlights a brick that you hover over, but only for the player who has hovered over it. Right now I can only make it so that everyone on the server see's it aswell.
Try using Instance.new() to a Current Camera Workspace if it isn't filtering enabled:
local p = Instance.new("Part", workspace.CurrentCamera) -- Only you can see this part p.Material = Enum.Material.Neon
