Hi, i am trying to create a game that has a spot light that character stands in and the light slowly diminishes over time, so it would slowly get smaller and smaller until its darkness, i have looked around the internet and their does not seem to be any help so i was wondering if you could give me a link or an explanation or video tutorial would be helpful thanks.
You can do it using blueprints. You can either decrease the light intensity with time or you can use post processing volume to achieve the effect.
First method is pretty simple if you know the basic of blueprints(if not check the video tutorial about changing light intensity here in Unreal Video tutorial series) and second method is mentioned in this twitch stream. Check at around 41:20 in that video
