The best guess so far ...
There are two ISOs ... one with threshold 0 and the other one with threshold
0.01 ...
the inner one is pigment 0 ambient 0 diffuse 0
the outer one has rgbt <0,0,0,1> and emitting media 1
because of the low threshold difference I had to change accuracy to 0.00001
and the formula has a maxgradient of 95 or so ... so it it very slow ...
I just realized, that instead of media I could have used fade_color 1,
couldn't I ???
