It's my understanding that you can EITHER have textures on the
individual blob components OR have a texture on the whole blob, but you
can't have some of each. It doesn't work like CSG operations where bits
of the parent object texture propagates down to the components that
don't have their own texture information.

What you could do is change the default finish before creating the blob,
like this:

   default {finish {Mirror}}

If necessary, restore the normal defaults after you've created the blob,
like this:

   default {finish {ambient 0 diffuse 0.6 reflection 0}}

This is exactly equivalent to writing "finish {Mirror}" on each blob
component.
