You gave me another idea for varying up the scales, though it's very rough. But it doesn't seem to be radial.
A smooth transition between conditions would fix this, and actually open up a huge possibilities in function texturing. At least in my opinion. Could this be achieved vanilla, or would Matt have to intervene on the code level? If you use a soft perlin, it works, but still a hard switch, and more wispy/warpy which is why I stuck with the voronoi.
