I ran into a similar problem with some blobs I made. I was trying to make a
generic flower (daisy), which meant squishing sphere components to make the
petals. I ended up having to make the flower about 100 units across in
order to eliminate MOST (unfortunately not all) of the visual artifacts. I
also ended up making the petals thicker, because thinner petals had huge
artifacts even at very large scales. At a scale of even 5 units across,
large portions of the tips of the petals got cut off, etc.
For example, instead of scaling a sphere component by <32, 1.5, 10> to make
a thin petal, I had to scale by <32, 4, 12> to get a useable petal.
