Aurora Borealis Effect Made Entirely in Unity

If you were looking for beautiful desktop wallpaper or wanted to learn more about making shaders in Unity, here's a cool project that will satisfy both needs. Technical Artist Kelvin van Hoorn has revealed an impressive new project, made for Technically Speaking Discord challenge titled "Aurora".

According to the artist, this is a raymarching shader and was made entirely in Unity by calculating the intersection points between the view direction and two spheres that represent the atmosphere layer in which auroras take place. These intersections are the start and endpoint of the raymarch.

What's more, the artist has released a short breakdown that thoroughly explains the entire working process. In this breakdown, Kelvin explained how spherical UVs were calculated, shared the workflow in Unity, talked about setting up the color, and more.
