Yow! I used max_gradient alone to see what POV-Ray was saying it wanted that to
be and its way beyond what the other isosurface evaluate parameters were.
Which BTW I finally ended up using MinFactor=0.7 to prevent any missing portions
of that one.
This current isosurface using max_gradient 10000 (sans evaluate) is rendering 5
minutes at only 160X120 resolution, incomplete of course.
Render message told me it needed max_gradient 7131910.500, so that really puts
the evaluate numbers up there and the render time is obviously going to increase
dramatically.
Sorry I don't have a solution, can only tell you that much. If there's a way to
reduce render times and still get a complete isosurface for this one I sure
don't know the answer. Unless something can be manipulated to do so and someone
else knows how to go about it anyway.
