How to make Beams Fade vertically

I want to make Beam that is transparent at the top but not the bottom but i don’t know how to rotate the beam.

the beam keeps going left to right i want it to become transparent at the top not the side

If you want the beam to travel sideways but be more transparent from bottom to top then your image in the beam needs to be faded from one side to the other.

Or do you want the image to fade from the blue edge moving upwards? If so you need to move your Beam Attachments from the ends to the bottom and top.

just place att up and down and rotate them (and change beam width to match part’s width)
