I could be wrong, but I think that there is only one "size" of partical in
MEDIA. (And personally, I'd like to know what size that is, for future
reference. I don't see that in the POV docs anywhere. Perhaps it's just a
mathematical "point" with no size at all.)
One way to achieve your results would be to set up an isosurface object,
with suitable values that create lots of tiny broken-up blobby-like pieces.
Alas, long render times would accompany that as well.
Perhaps another method (just a guess) would be to set up a MEDIA / INTERIOR
/ DENSITY block with a density_map or color_map that includes some
transparent "colors", perturb that with a granite
pattern (or turbulence), then apply that 3D result to a sphere. Or "fill"
the sphere
with it. Or something like that! Can't say that I've tried this, but it
seems like it would work, generally speaking.
