Same problem again. This time I used "evaluate" from the start, but it 
seems not to make a difference.

Never mind. I found my original version of the script, and there was a 
hack in it to make it work. I don't know why the hack works.

Ahhh. Too late, I already replied in the other message thread. Without a real
answer.

That 2nd isosurface was incredibly slow and required-- so said POV-Ray-- a
ridiculously large max_gradient.

I could only hope you or someone else might get an idea of how to change the
functions enough to fix it. If that was the cause.

Good to know you found something.
