Pretty new at Unreal, need some advice with lighting

I want to make a game in which the character’s footsteps emit light, but I don’t want that light to actually bounce off of the character or other actors in the environment, just create a small radius of luminescence on the floor (and the surrounding environment, e.g. walls and the rest of the room if the radius is large enough. Sort of like a sonar pulse) with each step. What is the best way to do this? Is it possible to spawn a light source with each step that grows until it disappears, but only affects one type of surface?

Look into making a decal that spawns on a trace down from each foot when the foot hits the floor, then make the decal emissive to get your desired effect

Use a combination between decals and blueprints -> so create an actor bp with a light in it + a decal actor. Then spawn it at the place where the foot hits the floor. https://www.youtube.com/watch?t=13&v=JI84nFuLMSo :slight_smile:

Thank you so much, guys!
