Introduction: Realistic Lightning Using Unity 2017 Beginners

About: HI my name is Abhijit Leihaorambam I am from Manipur a small state in India. I love science.

In this tutorial, we will create an awesome looking realistic lightning scene shown above in unity using Progressive Lightmapper and post-processing stack.

Make sure you have some basic knowledge of unity interface and a unity3d software on your computer.

You can skip this part if you didn't want to know what is Progressive Lightmapper.

The progressive lightmapper is a path tracing based lightmapper backend that provides baked lightmaps and light probes with progressive updates in the Editor.The progressive lightmapper goes through a short prepare step (geometry and instance updates, G-buffer and chart mask generation) and starts producing the output very quickly. New lightmaps and light probes are shown as soon as a new intermediate result is ready. This allows for a very fast iteration workflow.
