I this video I have made Thunder lightning effect using Particle2D node, Timmer, and world environment. This lightning is fully random and thus looks real. making these kind of lightning is very easy and all you need is just some images.
by learning this you will now able to create many similar effect like fire, explosion, waterfall, etc.
