Those experiments are not directly related with glow but all the effects created in this section use glow which improves in a drastically way the overall look.
This experiment combines a lot of effects to make this gem material, such as parallax, refraction, offset mapping, reflection, volumetric rendering, thickness, etc.
I was very inspired by Walt Disney Pictures and Pixar Animation short : La Luna, released in June 6, 2011.
I decided to try the Unity Shader Graph with the Lightweight Render Pipeline combined with some post-processing effect to achieve this star material. I also used additional custom techniques taken from the previous gem material and created a custom glow effect.
Another quick experiment made with the new Unity Visual Effect Graph which allows to animate millions of particles in real-time. I also added some post-processing effects like glow as always.
