Refined my original setup which was a mess of somewhere around 30 nodes. I knew a lot of what I was doing was "stacking" rather than achieving something unique with less PFs. If that makes sense. In fact, I believe I have created a better Gas Giant than my previous, with half the nodes, and added global clouds displaced by the terrains same displacement (thinking of possible altering this), so it mixes with the spots. Spots are also still masked in with the master cloud form displacement as the spots PF is rather chaotic.
Forgive my rich colors. I have a thing for this sort of color palette.
Post processing: Levels (increased mid-point), Bloom (made an action based on levels and Gaussian blur and desaturation), High-Pass + Smart Sharpen.
