This article demonstrates how to create a flickering light effect in Unreal Engine 5 using a combination of a spotlight and a custom Material to create a sine wave that affects the light’s emissive color over time.

Great tutorial and looks awesome for what I needed. How can you set multiple lights to use this this loop, but at different speeds/starting points so not all of the lights flicker at the exact same time?

Does anyone know how to make lights flicker when “Substrate Material (beta)” is enabled in project settings as I find that it is in my UE 5.5 cinematic project? I’m a complete noob so I didn’t realize it was enabled. Enabled, it gives a different blueprint layout when creating materials that don’t work as you detailed in this tutorial. Also, in the Details panel, the Material Domain is greyed out so it’s impossible to switch from Surface to Light Function. I disenabled the Sub Mat setting and these
instructions worked perfectly, but unfortunately my entire project is wrecked when disenabled so I need to find a work around to get the lights to flicker with it enabled. I appreciate any help anyone is able/willing to offer.
