I agree, the texturing is bad but the modelling is good.

But of course! Don't we all? :-p

Already fixed!

Sure. Lets see, a basic hint......Ok. To me, blob modeling is a lot like
modeling with clay. You can add bits, you an scoop huge chunks out, you
can taper to a point. My personal trick, without which I couldn't make
anything, is what I call Feathering.
It's taking a blob component, say a sphere,
sphere {0,1,1 scale <30,5,70> translate -4*y-40*z}
and copying and pasting it several times. Now go back to the first three
numbers:
sphere {0,1,1.......
sphere {0,1,1.......
sphere {0,1,1.......
Now you decrease the blob power (third number) and increase the radius
(second number). Leave the first alone.
sphere {0,1,1/2.......
sphere {0,1.2,1/4.......
sphere {0,1.4,1/4.......
Note how the powers of the three components add up to the power of the
sphere you started with. When rendered with other components this serves
to greatly smooth the lines between components. The downside, however, is
rather messy code. Still the speed decrease is minimal. I once had a 10
component blob and a 10000 component blob. The first only rendered one
second faster than the second!!!! You must remember to manually bound your
blobs. To do so put the blob in a union {} statement,
union {
blob{....}
}
and use the same bounds on both.
union {
blob {....
bounded_by {...}
clipped_by {bounded_by}
}
bounded_by {...}
clipped_by {bounded_by}
}
This will seriously speed the render up!
Hope this helps you!
