How do you 3D model the northern lights?

To 3D model the northern lights, start by creating a basic landscape in a 3D software like Blender or Maya to represent the ground and sky. Use volumetric shaders or particle systems to simulate the ethereal, flowing appearance of the auroras, applying gradient colors such as greens, purples, and blues. Animate the light patterns to mimic the natural movement of the auroras, and adjust lighting and transparency settings to enhance realism. Finally, render the scene with appropriate lighting conditions to capture the shimmering effect of the northern lights.
