I actually need to create a searchlight cylindrical “target direct” light, is there a way we can do it in ue 5.3 ?
Actually, all the light rays are parallel, so the emitted light forms a cylindrical beam with a consistent radius, so, the UE5 spotlight, is conical and will not work… This photo shows an example:
Basically, you do it with a mesh 
Just a mesh with an emissive material.
but the mesh doesn’t have feathered edges like the light in the reference and doesn’t fade out at the top end
It’s up to you to do that in the material 
You can do something like this with volumetric fog, but you might find that you have to tweak things so much to get the effect, that you compromise the rest of the scene.
nice I will try it and let you know
