See my original post here..,

https://news.povray.org/povray.binaries.images/thread/%3Cweb.626c0f28ac9c0ae18d86850a6e066e29%40news.povray.org%3E/

An animation of 'solid'-looking emission + absorption medias, using POV-ray's
object pattern for the media.

A mesh2 model as the object pattern, with an image_map as the media density...
then all of it heavily distorted with warp{turbulence...}

The slight flickering in the media is, I think, the result of rotating the
entire media object while the media's intervals/samples remain 'fixed' in
spatial orientation, by default(?)

This animation is similar to the previous one, but the Bunny artwork fades into
a multi-colored cells pattern... just for fun. ;-)

Here's another one!

One of my experiments ended up looking like a nebula of some kind, so I added a
familiar-looking(?) spaceship, and a background photo.  This is just emission
media.

The wispy look required a HIGH samples count, to try and keep the media from
showing 'discontinuities' between the samples/intervals as the camera moved
through it. (I should have used an even higher value.) The camera movement is
within a very small space.

Total render time for 400 frames: about 9 hours.

You are correct, you need a higher value for your samples, like about 
50% more.
Another option would be to make the shell slightly thicker. Not by much. 
Maybe only 5 to 10% thicker could make a big difference.

is _real_ nice, and also the "fly-though" works for me.  cheers.

I love that one.
