I should have checked into this more before posting my reply to your other
message thread. Still rendering one more animation as I write this.

Renders slowly with evaluate so I tried doing as the documentation says and put
another parameter in there.

#local MinFactor=0.4;

isosurface{...
evaluate 15*MinFactor,4*MinFactor,0.7
....}

Of course you might need to try other numbers.

And I wanted to say before, too much in a hurry to post answer, that I'm
fascinated by your work on this color thing. I'm unable to figure it out yet, if
ever!
:)

And I was right! That animation test finished and had missing pieces, I didn't
notice during the renderings.
Upping the MinFactor to 0.52 seems to be the fix, but you probably shouldn't
depend on that.

Good luck with it Mike.
