Few days ago I saw this great promo by this talented gentleman named InlifeThrill and I thought this could be awesome as a tutorial so I tried to create a similar animation from scratch.This time we won’t use Optical flares but you can improve this effect with your own lens flare plugins or you can purchase the animation by InlifeThrill. Let’s get started!
