This script is so easy, I don't understand why it doesn't work!
Here it is:
local B = script.Blur1:Clone()
B.Parent = workspace.CurrentCamera
local C = script.Bloom1:Clone()
C.Parent = workspace.CurrentCamera
local T = script.ColorCorrection1:Clone()
T.Parent = workspace.CurrentCamera
All it should do is put 3 things in the player's camera, making a cool yet creepy effect.
Any ideas?

Don't assign variables and try after Clone() say Clone().Parent = workspace.CurrentCamera
^ Doing it this way is completely fine, especially if the OP wants to edit these objects with the client later on.
The problem may be that, as far as I know, that those objects may only work with the Lighting service. Try testing that out, and see what happens. :o
They need to be in Lighting instead of the Camera to work.
