Hi
I’m trying to make point lights change colour every so often and I would like to combine them to save time,so may I ask if there’s a way to do this in UE4?
Thanks!
They can’t be a mesh, because a mesh is just a ‘dead’ object.
You can combine them in a blueprint:
It’s nicer with meshes and emissive. Really depends what you’re trying to do:

Can these be done with spotlights too? And how do you set up the point light intensities and such? I would like to make it like this Grand Indonesia's Dancing Water Fountain - Part 2/2 - YouTube
To do that, you would need to find out about Niagara ( particles ). Specifically, ribbon particles:
This vid is in the right sort of area.
Can you make a tutorial video if this? Thanks
That guy has, no?
I’m talking about the point lights blueprint you showed me. How do you do that?
Ok, with just the lights, or the spheres?
Both please. Thanksss
Well, the one for the lights is already up there. For the spheres, just make an emissive material:
and make a material instance from it.
The spheres BP looks like this:
For the Point Lights blueprint, what “Get” action is that, because there are many actions with the “Get” word that it’s quite difficult to find.
GetComponentsByClass, with ‘PointLight’ as the class. You know you can zoom in by clicking the pic, right 
It’s the same for the sphere one, but then the class is ‘StaticMesh’, of course…
I’m talking about this one 
Sorry. Drag off the array and type ‘get’ in the search box.
