When I use media with blobs, I get a black line where the
containerobject intersects with the blob-object.  I need to add media
to my blobby alienfighter, but how?
I suppose this is a bug?

'blob' is inherently that way even without media, that is when there is extra
effort in the calculations to make them I guess.  Have you tried it with 'sturm'
added?

Several suggestions. Try to use 'sturm'; try increasing
max_trace_level (you know about the little stone...); if you're using
spherical densities make sure they don't leave the real radius of the
blob (check out the docs for the exact formula); model your container
object so that it does not intersect the blob :); other than that I
can't help much without seeing a picture and/or code.

I'll try sturm...

The density is completely inside the container, so that's not the
problem.

I already tried that.  It works, but it's very difficult to do.

Just make a blob and a spherical container with media.  Make sure the
container intersects with the blob, and you'll know what I mean.
