I had tried that too, but i couldn't get mine to look that nice. I had to
crank up the max gradient. i'm not super familiar with isosurfaces yet. did
you just do something like "f_sphere(...)+myPigmentFunction(...).gray"?

by the way, i can't take any of the credit for the multiple warp technique.
someone here used it this year for a really hot looking media fire. it
looked amazing. I only used it for pigments instead of densities. i can't
find who it was now.
