What better thing to do in lockdown than to make this fully 3d animated Northern Lights? In this tutorial we go in depth on shader nodes such as: Color Ramp, Map Range, RGB Curve and Noise. And I promise not to wear a giant Bob Ross wig while doing it.
This tutorial is ok for beginners but you need to know your way around the Blender interface, so if you're just starting out I recommend going through the official Blender Fundamentals training first:
