Procedural Gas Giants

Similar to Procedural Stars, Gas Giants are built with domain warped FBM noise, but the pattern is kept constant around the Y axis, to produce distinct vertical layers.

Setup

As with procedural stars, the quickest way to add a new gas giant to your scene is by using the custom menu commands added to Unity’s context menu. There's options for gas giants with and without asteroid rings.

MonoBehaviour Component Reference

Similar to the Stars, Gas Giants are built with domain warped FBM noise, but the pattern is kept constant around the Y axis, to produce distinct vertical layers.

You can control the variation along each axis using the X and Z Scaling and Y Gradient Scale and Strength Properties. Observe the difference between the Saturn and Jupiter samples in the Sample Scene.

Gas Giant Glow

The glow effect is a full-screen 3D post-processing effect, same as the Star Corona Glow. In addition, it uses the main light direction to darken parts of the effect.
