Volumetric Light Function?

Does anyone know how to set up this volumetric light projection?

Thanks for any little help, ideas and thoughts.
Appreciate it.

Hey, these seem to use light function materials. Basically you create a shader / material and with some trickery you can make lights display various textures, flicker etc. Here is one that I have created, it’s very modular: Elias Wick | Modular Light Function. I do suggest that you purchase one if time is of the essence. Learning how to create shaders can be time consuming and difficult at times.

Here is a tutorial to get you started: UE4 Lighting: Light Function Material - YouTube
