I had a free evening!

Recently I was shown a fantastic aurora effect and I wanted to take a shot at replicating its look from scratch. It turned out to be relatively simple:

  • Create a Quad in your favourite 3D tool
  • Subdivide that quad along one axis
  • Randomly pull vertexes along one axis
  • UV wrap
  • Bring the model into Unity
  • Create a two-sided shader with alpha, two textures of noise that overlap to create colour
  • Cycle the UV’s on a noise image to get the colours showing at “random”
  • Bloom + Motion blur effects on the camera!

Here’s the results, please forgive the super-low poly model, it was my first attempt at making a car.
