I wouldn't call it a bug ...
The BLOB-Object has no pigment ... so it complains ...
does it also complain, if there's a #default given?

if so, then I think one could talk about a mistake in the
design, but as it stands atm I think it should complain
even if all the components have a pigment attached, because
the warning isn't thrown by a component, that complains
about a missing pigment but it comes from the blob, which
has, in fact no pigment ...

I see nothing wrong with the completed render.

No. I had removed a #default texture and then noticed this warning.
Adding a pigment{rgb 0} outside the sphere components removes the
warning but slows the render.

there shouldn't be anything wrong ...

really ... this is interesting ...
Are you really sure about the slowdown?
this could really be a misdesign then ...

... but I'm not programmer enough, to prove that ...

No, your statement is incorrect. A sphere requires 2 parameters, a 
vector for the center and a scalar radius. A sphere blob component can 
take 3, the additional one is a strength parameter. Neither of them take 
a color value.

  A CSG does not complain about not having a pigment defined if every
subcomponent has a pigment defined. IMHO the blob object should work in
the same way.

My old scene used a 1000 component blob with a calculated texture for
each component. I remember moving the finish from the texture block to
the end of the blob object and not being happy with the new time
(megapov 0.4). I've just tried this again with pov 3.5 and can see no
difference in render times now.

    And if you're gonna expand a vector out and say it has 3 components, you
should expand out the texture modifier as well, and it's sub-components, and
all their sub-components, and.... So, a sphere takes an _infinite_ number of
components... ;)
